ASUS P5W DH - Problems + Fixes Thread

[Smy]

her my oc for now.I will try for 3.6ghz letter
cooler is a scythe ninja PLUS rev. B with 2*120mm titan fans.
vcore is 1.55v i bios 1.5v mch and 1.60v fsb.

Edit got stabil on 3.5ghz now

Hello fellow p5wdh owners,

I have red this whole thread (!), and learned a lot from it. However, there is one problem i was not able to solve. I have a raid0 connected at the ich7r intel, and a third standalone sata hd at the intel sata4. Works great.

I did connect a fourth external sata hd at the jmicron controller (needs to operate as a standalone hd) (i plan to connect a 5th sata hd at the ezbackup connector, after removing the cap). This hd does not show up at the bios or in windows (when using partition magic). The external sata hd is formatted and contains data. When i choose in the bios the option "raid" at the jmicron controller (just testing), the hd shows when booting. Still nothing in windows.
I have installed jmicron raid controller software (because i thought i needed to install a jmicron sata driver, to make the hd visible at windows), but no result. Anyone has a clue? Thanks!

Sorry I meant to include all that
bios = latest form the asus site 1707 , but I have also tried 1101 1402 1801(beta) 801. Even though I have this bug when I get into windows i have no problem flashing. Settings in bios are fail safe defaults, as i said I have to reset them just to get the pc to post.

The motherboard is 6 months old

full system
Asus P5W DH Deluxe WiFi (Socket 775) PCI-Express DDR2 Motherboard
Intel Core 2 DUO E6600 "LGA775 Conroe" 2.40GHz (1066FSB)
NZXT Lexa Classic Series Ultra light Aluminum Midtower
Samsung SH-S182D 18x18 DVD±RW ReWriter (Black)
Connect3D ATI Radeon X1800 XT 256MB GDDR3 AVIVO TV-Out/Dual DVI (PCI-Express)
Enermax Noisetaker 485W EG495AX-VE(G) SFMA ATX2.0 PSU
Scythe Ninja Plus Heatpipe CPU Cooler (Socket 478, 754, 939, 940, LGA755)
G.Skill 2GB DDR2 HZ PC2-6400 (2x1GB) CAS4 Dual Channel Kit
Western Digital Raptor 74GB WD740ADFD 10,000RPM SATA 16MB Cache

It does sound like you have a corrupt bios on the motherboard so i would RMA it back if you have allready changed the CMOS battery and tryed different bios versions.

I've been having this board for a few months; however, I noticed today that when I push 'power off' button on the PC case the computer goes to 'EZ-Wifi' mode and doesn't switch off. The 'power off' button used to switched off the PC, but not any more. I wonder, does anyone has a similar problem? Thanks for any advice or ideas.

This is a total guess but try and looking in your BIOS. I remember seeing something about the power on/off button in there, maybe somehow it got changed.

Then again I could be wrong, unfortunately I'm doing work right now so I can't reboot and check for you right now.:cussing:...

[Krusty]

Thanks, I checked it before and I couldn't find anything like that. I'll try to check it again though.

I remounted my CPU, and switched to using Arctic Silver 5
I now have a 3.5ghz overclock @ 1.45v in the BIOS, about 1.41 vdroop.
I enabled SPD, let Asus have its fun. Got a 1:1 ratio for the memory out of 2.1v, run everything disabled except firewire and one onboard gigabit ethernet.
1602 BIOS
2.1v memory
1.4V fsb term
1.65v mch
Auto on the southbridgeD
Disabled PEG link.
101mhz PCI-Express Freq
Turbo mode
PCI to 33.33mhz


389 x 9, Low 50's idle, even 48-50 for a while on cold boots.
I lapped the southbridge, my Scythe Ninja, my CPU, my Swfitech northbridge, applied Arctic Silver 5 to them all, and I had the world of a difference temp wise. You might remember me complaining of an absolute wall at 369 FSB for me, and insane temps. Well I do believe 1 of the corners on the Ninja's mounting corners made of plastic were not on the way they should be. Never the less......I took the board out, cleaned the wiring job up more, and spent some time doing it better. Everything runs cooler, plus everything I had to complain about with the P5W DH is pretty much erased. I enjoy this board, and hope Asus does work out some better memory options in the BIOS next time.

My friend and I have L632A's
I have e6600 @ 3500mhz @ 1.45v
He has e6400 @ 3350mhz on P5B @ I forgot....419x8 he runs on the same Team Xtreme DDR2 667 memory.

[factory81]

I did Super PI 1m time of 14.781s on my P5W DH, 389x9 @ 1:1, SPD enabled. Rock solid L632A's we have here.

My friends P5B was a $125 965 board but it overclocked to 419x8 SPD enabled 1:1, same memory, and L632A e6400.
http://student.muskegoncc.edu/~pringnitzr/ryancomp.jpg < this is his L632A E6400 w/ Scythe Mine CPU cooler, 50mm fan over northbridge, 4x80mm case fans, 1x120mm side case fan, plus power supply fan. I am proud of the cable job I managed. 1 IDE cable, 2 usb headers (one front , one back ). 2 SATA cables, power cable for 2 sata drives, cd-rom power, case buttons / led's, video card 6 pin, mobo 24 pin + 4 pin, all the fans.....
I gotta post screenshots + pic's of my stuff.
English work to do then I get to work on my HTML class stuff (which I just go on about my computer as I learn more crap and use it on the page)

Hi,

You can actually run 4 sata hdd's off your intel ICH7 southbridge, and I would highly recommend this over trying to get the JMicron and/or the SiliconImage crap(ez-backup) working.

Plug your drives into SATA 1 (red), SATA 3(actually#2 black), SATA 4 (black), remove the jumpers off the ez-backup area, and plug into the right yellow ez-raid port (actually SATA2). I don't remember the physical marking of the right ez-raid port, so please forgive me.

If you have the jumpers off and boot with the drive attached, you'll see it in the list of the ICH7 area as your box posts, if it's in the wrong one, you won't see anything. Also, you may want to set the DH Features Change option in the bios to Enabled when you take out the jumper and attach the drive to have it tell the SiliconImage crap to turn off.

Bingo. You have 4 hdds on ICH7 and can turn off JMicron in bios.

Having problems pushing past 380 fsb. Once I go over 382 with vmch 1.85 and vfsb to 1.5 the system wont boot into windows. It also has a hard time posting and sometimes takes 3-5 minutes to get into bios. Is this the furthests my board will go?

It's not my processor or memory. I tried 380x8 and x9 and I can boot at 382 but anything more and the system wont post.

Any suggestions?

anyone know what the EEPROM update for the wifi ap solo actually does/fixes?

Driver update RTL8187L EEPROM is required if you can see the WiFi module in Device Manager, but still fail to connect to any Access Point (AP).

This actually has to do with how the motherboard works. It looks at the default multiplier of the cpu, looks at the fsb you set, and must POST at that, after the POST, your board adjusts the cpu multiplier to what you set it to in the bios.

Our suggestions are to boot at the multiplier that you want to test a higher fsb with, but boot at a bootable fsb. If 380 can get into windows, that's fine. Once in windows, adjust tRD and tRFC to 8-42 (not sure the order, it may be tRFC-tRD) using memset 3.0 or 3.1. Search the thread for memset to find download.

Then after you tweak those settings, download systool, clockgen, or setfsb to manually start adjusting your fsb upwards. I can't remember the full name of the chip you need to set, but look for the last numbers being 123.

Sorry for my unknowns; I'm at work, but it should be enough information for you to do what you can to achieve higher fsb.

Best of luck.

Interesting.. I wonder.. My setup can do 400x8 at vCore set to 1.43 in bios (shows 1.38 in bios own monitor). But when i try to do 400x9 i have to go alot higher on the vCore, around 1.5-1.55 or so.

400x8 = 3200mhz, vCore set to 1.43
356x9 = 3200mhz, vCore set to 1.35

The cpu at same speed but needs different voltages? I'm guessing it has to feed on more volts when its fsb is faster? is it worth the higher fsb? or should i go with 9x multiplier up to around ~370 using vCore 1.43?

Wow, I'm impressed you can actually post at 400x8 at such a low vcore. My melon of a CPU :mad: may be able to post higher than 385, but only slightly, no matter if I put 1.65vcore to the chip or not. If I want to do a high 8x multiplier, I have to boot less than 385x8, then clock up inside windows after adjusting my tRFC and tRD. I can go to my sig, basically ~3500mhz either 8x or 9x.

Intel CPUs seem not to be as FSB dependent as AMDs, so run what benchmarks you like in how you plan to use your computer, and see what you find. I've found that a higher multiplier and lower FSB outscores a higher FSB and lower multiplier in gaming (keeping all other things the same, ie: memory timings), ultimately the higher cpu clock being the goal. This may also only be fact on our i975 chipset as well, since our mb at normal 1:1 with original multiplier will outscore an rd600 and i965 at ultimately higher fsb with original multiplier. <-- I don't understand this, but whatever. It's a choice that we made, either intentionally or unintentionally when buying our board vs another chipset one.

Lastly, how much voltage *should not* (stressing the should not, so do not hold me accountable in a year if your cores die ;) ) affect the CPU as long as temperatures are at reasonable levels at the cores. Unfortunately since these CPUs are so new, we cannot know the long term impact of pushing heavy voltages to them over long durations of time, even if temperatures remain acceptable. Those of us with earlier week CPUs are kind of forced to push heavy voltage to hit high numbers, and in turn are forced to use liquid or other radical cooling types to offset the higher voltage required.

Hi,

I have an E6400 cpu that is running at 2.74ghz @vcore 1.400 ..

When i tried to bump my fsb to 353, i received an error "overclocking failed or overvoltage failed" and when I up my voltage to 1.4375+ i received the same error again ..

Anyone knows how to fix this?

I have an Arctic Pro 7 HSF and my psu is Seasonic S12 550 watt

Thanks. I'll try that but your explanation about Intel being less FSB dependent holds true for my system. 340x10 and 380x9 had little if no difference in performance. Mostly because I kinda have the memory at a sweet spot at 340fsb but I'm going to try 425x8 and see what I get in terms of performance. I know my CPU and memory can handle it, we'll see if the board can. 425 with a 4:5 memory ratio will get me back to the sweet spot in my memory.

[Hutch]

Can anyone update me on the fixes, as this thread is really long and I haven't uses my P5W DH since September...

Did one of the new bios allow for vMCH higher than 1.65v? If so then what's the highest? My Board was scaling very well with increased vmch (+.08v added 15mhz FSB stock NB cooler, 1.73v.) Have instant access to negative ambient temps now so I can go ahead and run more than 2v+ if possible ;)

Also, what are the ram ratios below 1:1? My ram has really sh1t the bed (thanks Gigabyte S3) and won't clock much higher than 820mhz...

I believe the last bios I used was 1101...

[Hutch]

Oof... someone help me out... how am I gonna put the heatpipe back on when I bent the pipe in 4 different places and lost the damn clip... I bent the pipe so that the NB is just about in place but of course it's about 1cm off the chip...

I think I'm gonna superglue it... What part of the NB cooler should i glue and what should I glue it to? I can glue it to the green part of the NB right (not the ACTUAL tiny chip in the middle...)

[shuiming]

vMCH voltage is base on your MB revision, not bios.

For XFI Music Owners:

yes you can disable the realtek HD onboard audio, its in the bios very easy to spot, once you do so windows will no longer detect the onboard audio.

The XFI Music was such an improvement for me. Onboard really sucks, HL2 sounds real now and music was never louder or better sounding. This sound card will be in my next 5 pc's over the next 5 years.

I run my E6600 with this motherboard at 3.4GHZ 1.425 VCore. Slightly OC'd in other words, and it's stable as a house ( atleast 7 hours Orthos :P). Sometimes when I boot after being turned off over the night i get this message from BIOS, "Overclocking or overvoltage failed". Either I press f1 to enter setup and just "Exit and discard changes" ( keeps up booting with no problem ) or press f2 to continue with default settings in BIOS-> means no OCing :( . Is there anyway to get rid of this meanless message so my girlfriend don't go panic and set my OC to zero everytime she boots the computer?

Hmm.. I had to do some modification cause one of the two hooks that hold the nb came off when I installed my thermaltake spirit II. Is this what happened to you? One of the hooks, or are you just talking about the stock stuff on the mb.

You really dont have to worry about the heatpipe as long as you have adequate cooling on your nb. I cut mine off and left the copper fin stuff on the mosfets.

I, too, just got an x-fi platinum, and completely agree with you! Holy cow what a difference in sound! I only have a 2.1 set, but I also have a pair of Shure e4c headphones (299$ retail), and my god the three-dimensional surround and crystal enhancement blow my mind!

Now I need to wait and find a deal on some nice 5.1 or 7.1 powered, wireless rear speakers to set around my workspace. It will make a nice addition to my Nintendo Wii, 32" lcd hdtv, 20.1" lcd monitor, modded Xbox 360, modded Xbox acting as XBMC, my rig, and my 3 terabyte server! :D

My first post is a question. I want to get the P5W DH system but don't have a need for the WI-FI or remote stuff. In other repects, is the P5W DH the same as the Deluxe without these things? Am I losing anything important by not getting the Deluxe? I want a good/fast system for video and photo editing and probably will not get into OC. Will probably get the E6600 for now and move up to the quads later this year (thinking that the quads are fairly expensive now and price will come down later with better performance point too and will be overall less expensive this route). Is the recommendation for this MB or something different?

I have a question about Windows and handling Core 2 Duo on this board. I can see in Task Manager and its CPU usage that when I ran a numerical simulation both of the cores are used for about 50% because of switching the task between the two cores. However, I would like Windows to handle the task better and to use only one core for 100%. I wonder, is there any way that Windows will stop switching between the two cores without manually setting it at Task Manager?
Thanks.

[Zeus]

So far, i like the board but have to master all bios settings.
The only thing that kinda surprised me is that there's no beep coming from the pc speaker at post.

Is this turned off in bios maybe?

I already tried to flip the connector over but it didn't make a difference, maybe the speaker is just broken.

Right now i'm running orthos at 3.6GHz @ 1.42Vcore set in bios (~1.4V real), tonight i will lower multi to find max FSB.

[Phoenix_TT]

I have a wk 24a e6600 and right now I can't to overclock to 4.0G

Settings are:

FSB: 439
Memory Voltage: 2.25V
CPU Vcore Voltage: 1.65V (appears to be 1.62 actual)
FSB Termination: 1.5v
MCH Chipset Voltage: 1.65
ICH Chipset Voltage: 1.2

Memory using SPD
DRAM ECC Mode: Disabled
Hyper Path 3: Disabled
DRAM Throttling Threshold: Disabled

Advanced CPU settings:
Modify Ratio Support: Disabled
Microcode Updation: Enabled
Max CPUID Value Limit: Disabled
Execute Disable Function: Disabled
Enhanced C1 Control: Disabled
CPU Internal Thermal Control: Disabled
Virtualization Technology: Disabled
Intel (R) SpeedStep (tm) tech: Disabled

I have Corsair XMS2 CAS4 6400 memory (2x512MB)

At FSB of 439 it will boot, but Windows doesn't start. So any ideas on what I can do to get Windows loaded ? If set FSB to be 412 at the same setting as above the Windows will start. Have I found the limit of my CPU ?

If I set FSB to be 440 it won't boot. Is my memory holding me back ?

[INJViper]

Try setting the FSB to 400 and then using Clockgen to up the FSB from in windows... I run my E6300 @ 400Fsb and when its time to bench I clockgen up to 450 in windows..

Well, I believe the issue that he has is motherboard/bios related. Specifically what, I'm not sure since I have not run into it. If he can run 7hrs Orthos, he's stable with his hardware, since it's a torture test for pretty much everything connected and operating in the system. He didn't say he dies after 7hrs, only that he left it on, successfully, for 7hrs.

Someone else that ran into this problem and solved it will have to pipe up and offer their resolution.

I would recommend to stay with the intel 975 chipset, since it performs great out of the box without overclocking, however you don't have to spend the cash on this board. There is a DFI Infinity 975 board for half the cost, and if you put on the new bios and do a couple of soldering vMCH mods, you can hit serious fsb. There was a thread on this by another member.

You can look at the DFI board here: http://www.newegg.com/Product/Product.asp?Item=N82E16813136168

Hi, you've actually just run into a problem that windows xp has that's inherent to how it operates as an operating system. It was not designed to run as a symmetric multiprocessing (SMP) OS, but rather single core, single thread. As Intel released their hyperthreading technology, windows modified its code to allow for this, and tweaked it slightly to fit our dual and quad core environments of today. What you see in the OS is what you get, unfortunately.

I'm not sure the back-end logic and implementation of SMP in Vista, or if it will handle symmetrical processing better, but you have to be also using an application that is designed for it as well. All of the large, workstation class applications do have support for multiple cores, even running on XP (like Adobe Premiere, 3d Studio, etc), but you won't be getting as much benefit as you would on a similarly spec'd unix based workstation that was designed from the ground up with SMP in mind.

I know MS was going this route, as were all the game developers, so I'm sure we'll see better utilization and better scaling of games and applications upon multiple cores in the near future.

So in the meantime, if you want to only stress one core at a time, you'll have to manually set affinity in your task manager. However, from what benchmarking I've done in various applications, forcing an application to use only one of the two cores actually cuts your overall processing potential in half. This may not be true for all applications, but just from what I've seen.

I have a wk 24a e6600 and right now I can't to overclock to 4.0G

Settings are:

FSB: 439
Memory Voltage: 2.25V
CPU Vcore Voltage: 1.65V (appears to be 1.62 actual)
FSB Termination: 1.5v
MCH Chipset Voltage: 1.65
ICH Chipset Voltage: 1.2

Heya Phoenix, I agree with INJviper.

Your settings all look great, so try and boot your max stable to get into windows first, then use Memset 3.0/3.1 to adjust tRFC/tRD to 8/42, and finally Systool, setfsb, or clockgen to manually step your fsb up in small increments to test stability.

I'm curious though; what kinds of temperatures are you running at full torture load with orthos or dual prime95s on your cores from CoreTemp or TAT? 1.65vcore is mighty high voltage unless you have a good watercooling/phase/peltier setup.

[iadstudio]

First I must say that this is my first system build and first OC. I knew this was a possibility but didn't think it would happen this soon. Lately my OC has been showing signs of being unstable. I've heard that an OC'd system will need to be pulled back eventually because of the voltage and electrical things that happen which I don't quite understand.

My rig has been OC'd to 340fsb since September and gets a lot of use. I've had to take my system from 340x10 fsb at 1.4vfsb, 1.65vmch and 1.525vcore (1.5v actual) to 333x10 with the same voltage. I think it's stable now but I won't know until Prime runs for a while more.

Is this the beginning of the end for my system? Is the CPU or the mobo causing the problem?

Thanks for the help, I just want to know what to expect and what I can do now?

[nicepun]

Well I had the same problem except that my OCs were a little higher than yours, I started thinking that it was my CPU when infact it was the mobo. I know of another person that switched mobos and everything was fine again.

[iadstudio]

Switch mobo's? Another P5W DH or a different mobo? What's my best choice now that the 680i are out?

Also, how much can I expect the system to degrade?

EDIT: and in reply to your OC being higher than mine... this is my first OC and I hope with a little experience I'll get up there with the big OC's.

Well I'm loyal so I got another P5W DH, the other dude went to a P5B Deluxe. I'm actually quite suprise yours started to give you problems with low FSB, but I guess each system is different. Oh yeah, don't quote me on been the Mobo, so far that has been the cause.

[Psitech]

I know I must be missing something, but will somebody tell me how to turn off "virtualization technology" in bios 1707?

[iadstudio]

I won't hold you to that but thanks either way. My system degrading so quickly may have something to do with my inexperience and over-volting to figure out this OCing thing. I read up quite a bit before I OC'd but it seemed like I had to pour a lot of volts into my system to get a decent OC out of it. Also, my NB ran pretty hot for the first few months until I got a fan on it.

hmmm. Prime just failed after 1 hour so I guess my work isn't done yet. F'n OC addiction! I wish I could just put the system back to stock and call it a night but I just don't have it in me.

What about running LED fans from the mobo connectors? could that be giving me problems. I recently switched my ExtremeSpirit and OCZ memory cooler to the mobo connectors.

EDIT: what's this symptom called so I can search it a bit?

There's only one way to find out, put the other fans back. I'm not sure that the name might be. What about your temps? I Fold with my rigs so they are always @ 100% CPU usage and so far they are going strong.

[iadstudio]

I'll try switching the fans. As for temps, the CPU has seen some high temps but it hasn't passed 55c in months.

I'm on air cooling, using a Thermalright Ultra 120 with 120mm fan. I have a 40mm fan on the NB too. On my list of things to do is to improve the air cooling setup in my case. I don't really heavily use my E6600 and P5W system, just playing at the moment. I've been trying to get 3.6Ghz stable with Orthos so that's why I've cracked up the CPU vcore to 1.65. The temps at idle in Windows are between 48-50°c. I have run Orthos for 10mins but then the temps jump into mid 60s°c, which is too high for my liking and so stop the testing.

I think 3.5Ghz is my stable overclock, but I've yet to really test this, might do this over the weekend if I can, then try using memset and setfsb.

I using 1804 BIOS at the mo. This one is dated 8/01/07. Haven't notice anything new in the BIOS options. I've tried 1803 and this is dated 4/01/07.

[nicepun]

that's why I've cracked up the CPU vcore to 1.65. The temps at idle in Windows are between 48-50°c

:eek: Man, I usually crank it up that high when I'm doing 3.9/4.0GHz benching. Do you have an older chip (i.e. week 23/24 etc.)?

Yes I have a week 24a (from memory). I bought the E6600 and p5w as soon as they were available in the UK. Had some spare money. At stock speed the conroe is very quick, so can only imagine what it's like at 4.0Ghz!

any got the same chip?

[roger_h99.nor]

Mine is also a 24A (x6800). It requires only about 1.48V (real) to be stable at 3,8 - which I think is pretty good. Mobo had to be droop-modded to achieve this.

A mod to keep the voltage at idle and load constant and with as little fluctuation as possible

Voltage is your friend! :D Set everything manual - 4-4-4-12 with 1.8v first, test if boot, then prime95s. If it fails, keep pushing more voltage until you're stable. Remember that you need more voltage to keep tighter timings at higher fsbs, and since we dont have any way to measure mem temperature, make sure you have some good airflow going around the memory and it's not hot to the touch.

[nickfd]

I fixed my sig to include my storage server as well. Figured since we all have extreme systems, we can also include extreme storage? :)

Very good explanation.

I firmly belive that vcore fluctuation on this board is THE major issue in getting high and stable OC's on this board. Before mod I got droops in the 0,05 - 0,07 area. After mod, TAT is the only test that shows different idle/load vcore (TAT is brutal :D ). Under TAT the vcore droops about 0,01V. 2x Orthos vcore stays stable, as it does under 3DMark 05/06.

Just tested Memory and everything and I'm stable back at 3.4ghz. I had the mobo overloaded with LED fans. I took most of my fans off the mobo and connected directly to the PSU and it seems all is well again. :woot:

[DeltaSniper203]

Hey guys, I have been following this thread for quite sometime now, and I have a problem with Overclocking now. Its strange because I didn't used to have this issue.

keep in mind that I dont change any settings at all through this period of time
first off here is my rig

ASUS P5W DH
2GB Patriot 5300
Core 2 Duo E6400
eVga 8800GTS

I have done everything on the front page
cpu 1.52V
MCH 1.85V
ICH 1.20V

mem. timings 5-4-4-15

I had my FSB at 422x8 and it ran fine (1602 bios) and then one day my comp would post but freeze, so as soon as it would post I pressed Del. and it showed all the stuff loading and scanning or w/e and i noticed that when it got to
"flash drive port 0" it would freeze, so i took out my flash drive and all other usb connections and it posted but when it did post it showed the speed at 2.12ghz rather than 2.13ghz (is that normal?) I thought the CMOS reset its self so i went into the bios and the fsb was still at 422, so i just hit F10 and it posted and windows started up.

I never had any stability issues, then when I would restart every now and then it would not post, and I would have to restart manually, so i thought it might be the bios, so i flashed to 1707 and that decreased my max fsb to like 410, so i tried the 1801, and that decreased it to 400 and while using this bios it somtimes would not post at 400FSB, every other time i restart it would not post, and it would show up as 2.12ghz when I restart again...this is really pissing me off because I literally can't restart without having to ether lower the FSB or restart twice...this all took place over the course of 2-3 weeks

Also i flashed back to 1602 bios and still no luck my fbs is now stuck at 395

I'm stumped, is my board going bad? I also tried to clear the CMOS but still no luck

[REwell]

I've got a P5w that I love!!! But when I hook up a 2nd video card (a crappy 128 video card just to have my 3rd monitor :D But when I boot up it says "no 24 pin power connector."

My 1st video card is just a simple VGA 7600GS nothing too power hungry.
I figured this could be a common problem with this board.

I just thought I would ask to see what you guys would say. Thanks!!!

[triggerc]

is there a program that will monitor vMCH and vDimm in real time in windows? It seems that I'm only able to get my ram stable at 400mhz with auto voltage on vDimm and I'm curious as what voltage the board is using.

[lawrywild]

No, but it should be around 1.84v and btw, buy a digital multimeter

Hi folks,

I'm wondering if someone could shed some light on why I can't reach a higher speed with my RAM.

I'm currently running:
Intel E6700 @ 3.5GHz (350x10, 1.55vCore)
Corsair Dominator PC2-8500C5D 2GB Matched pair @ 876MHz @ 5-5-5-15 (manually set, but rated SPD)

Now I can't push the FSB any higher, even with going higher than 1.55v (which I don't want to do, as it's already high enough for air imho), and I can't change the bios FSB:RAM ratio any higher.
I've also tried lowering multiplier to 388x9 (3.492GHz) but the system won't stay stable - regardless of the RAM speed.

In each situation, I've tried maxing out all the other voltages (vMCH, etc) but nothing makes any difference... The machine will post but won't boot into windows when I select 950MHz or 1050HMz (the 1050MHz limit I understand is with the chipset, but 950 shouldn't be a problem??)

[Nosfer@tu]

Hi,

You can actually run 4 sata hdd's off your intel ICH7 southbridge, and I would highly recommend this over trying to get the JMicron and/or the SiliconImage crap(ez-backup) working.

Plug your drives into SATA 1 (red), SATA 3(actually#2 black), SATA 4 (black), remove the jumpers off the ez-backup area, and plug into the right yellow ez-raid port (actually SATA2). I don't remember the physical marking of the right ez-raid port, so please forgive me.

If you have the jumpers off and boot with the drive attached, you'll see it in the list of the ICH7 area as your box posts, if it's in the wrong one, you won't see anything. Also, you may want to set the DH Features Change option in the bios to Enabled when you take out the jumper and attach the drive to have it tell the SiliconImage crap to turn off.

Bingo. You have 4 hdds on ICH7 and can turn off JMicron in bios.

I will look forward to trying this :D

Does the 2 Asus EZ sata controllers have to be disabled?

Can't help you but I have a very similar build to you and was interested to see how much voltage you need for 3.5. I'm pushing 1.525 in bios (1.5 actual) to get 3.4. I was wondering if your vcore is what you set or actual voltage with droop considered.

Also, are you cooling you NB.

Finally another user who's having similar temperature readings as me!!

I did post a while back with a screeny, but at that point nobody else had seen it before!

To cut a long story short, I'm pumping 1.55v (in bios at least) through my E6700, running at 350x10. This is with a zalman 9500 and AS5 - the AS5 appears to make no difference from the standard zalman paste.

Maybe we've both got defect boards!?

Just thought I'd say you're not alone!

I have an HR-05 heatsink on my NB w/ AS5, and I just noticed that the entire heatsink gets extremely hot. If I run stock, it gets warm. If I run my E6600 at 3.2Ghz even with all stock voltages it gets really hot!

I'm now convinced my 356fsb wall is likely due to limitations of my NB. Any ideas as to how I can decrease temps of my NB any further? I run VMCH at "Auto", and increasing its voltages all the way up to 1.65v (max on my board) hasn't helped me (actually has hurt my OC a bit)...more evidence it is the heat being generated by my NB that is holding me back.

Are there any other BIOS settings that can decrease temps of NB?

You're just going to have to cool the NB better. make sure you're getting good Airflow through the heatsink and you might need to add a fan to the system. I have a 40mm fan mounted to the stock HS and it dropped my temps by well over 10c.

Right now I'm dealing with a monster Vdroop. I've had a lot of problems lately, mostly unrelated to each other, but now I'm trying to get 250fsb stable and the vdroop keeps widening. When I had the vcore set in bios at 1.525 the droop was .02 ish now I have the vcore in bios at 1.55 and the droop is closer to .05v. I really don't want to do a vdroop mod but it looks like I might need to.

WTF Asus !!! These boards have a lot of potential but are temperamental.

[Zeus]

This one has probably been answered a thousand times but i headed to bed @ page 40 of this thread so please forgive my ignorance.

Asus PC probe II says my CPU temps under load are 46C but TAT say it´s 55C. this is while running Orthos at 3.7GHz and 1.46Vcore.

Now which one is a liar?

Ok thank you.

What do you use for measuring Vcore?

PC probe is showing a nasty droop is that right?

[triggerc]

yeah both PC Probe and Speedfan are showing nasty droops. Maybe it's related to the PWM getting hot? Should I get some ramsinks onto the Mosfets?

[Shpoon]

I've got a question...do I just have a crappy chip? (I think it's week 23, I forget :p:)

I can get up to ~350 +/- 3 with 1.3125vcore. To get to 360, I need 1.5 just to post! I can't even get 370....am I missing something and vcore isn't the answer in this case..

[iadstudio]

There's a "Ghetto Mod" for the P5WD2. I'd like to know if this works for the P5W DH as well. A simple pencil mod would be nice for the vdroop.

Anybody know if this works with the P5W DH???

[Seb R]

I've set the vCore to 1.55 in the bois, don't know what the real voltage is as I don't have a multimeter! I'm not cooling the northbridge, it's only got the standard heatsink+heatpipe stuff on it.

Can't help you but I have a very similar build to you and was interested to see how much voltage you need for 3.5. I'm pushing 1.525 in bios (1.5 actual) to get 3.4. I was wondering if your vcore is what you set or actual voltage with droop considered.

Also, are you cooling you NB.

Sounds like we have the same settings almost. 1.5v in bios gives me 1.50-1.53v in speedfan. No multimeter here either.

Have you replaced the NB and SB TIM? I have a extreme spirit II on the SB and a 40mm fan on the NB with those metal covers taken off. Unfortunately you have to void the warranty and replace the TIM with Arctic Silver and loose the covers. That alone could give you a 10-15c temp drop on the NB.

Use the touch test... if the NB is too hot to hold your finger on it for 5-10 sec then you definately need to cool it. I would assume maximum cooling precautions should be taken either way if you want to really push the system.

Also, I have my memory at 2:3. This memory doesn't like tight timings so the extra bandwidth is helpful since you can't really tighten timings too much.

Edit: I just saw that you have 4gb of memory. Is that true? If so that could be limiting you memory multiplier but I would still try it.

Hmm thats odd. I can reach 400 FSB completely stable, but at 415 I can't even post. I'd just say make sure you have everything disabled you don't need that could be interfering with your OC. Checkout Kastaar's bios if you'd like, he made it to 440 FSB. (http://users.pandora.be/kastaar/HO/Allendale/MaxBench%20P5W%20DH/)

And as far as the NB goes, I also have the HR-05 on my NB, but I have an Antec 900 case and a 120 mm fan on the side that blows virtually right on it and my temps are fine, it doesn't even get warm to the touch except way down by the base.

You must be doing something wrong, my week 32 E6600 is running Orthos at the moment at 411x9, no problem 1.525Vcore in bios = 1.49V real.

The board's limit is ~435MHz.

I will post a screen when it has passed 8 hours.

[Zeus]

yeah both PC Probe and Speedfan are showing nasty droops. Maybe it's related to the PWM getting hot? Should I get some ramsinks onto the Mosfets?

The mosfets that regulate Vcore are covered by this heatpipe thing, i even have this turbo lookalike cooler attached to it, i'm still seeing droops.

Some almost forgotten NF7-s memory's popped back up in my mind. :(

How much i hated the looks of my NF4 ultra-D with is pathetic yellow and orange slots, voltage regulation on that board was rock solid.

Link to Vdroop mod anyone?

[Hutch]

Hmm.. I had to do some modification cause one of the two hooks that hold the nb came off when I installed my thermaltake spirit II. Is this what happened to you? One of the hooks, or are you just talking about the stock stuff on the mb.

You really dont have to worry about the heatpipe as long as you have adequate cooling on your nb. I cut mine off and left the copper fin stuff on the mosfets.


I actually lost the clip that holds the NB in place... I was trying to do what you did (few months ago) and I was struggling to get the NB and heatpipe seperated.

Since the bottom of the heatsink already has that soft stuff on it I figure whatever is below it can't be hurt by a little super glue... ;)

Just curious, what do you store on that 3tb??!! :banana:

:) I'm addicted to archiving stuff!

Ever since I got my LCD HDTV, I use it to stream high definition television shows, DVDs, and other misc things through my XboxMediaCenter or the video out on my 8800gtx.

Outside of movies, I store music, games, and apps I use as well, but all these take a small chunk of the overall percentage of space eaten up by all the tv-series, dvds, and other video formats sitting on the arrays. With h.264, VC1 and the other HD codecs, I think we're going to start seeing multi-terabyte as the norm in people that do any kind of work or storage of video technologies.

[nickfd]

Hi folks,

I'm wondering if someone could shed some light on why I can't reach a higher speed with my RAM.

I'm currently running:
Intel E6700 @ 3.5GHz (350x10, 1.55vCore)
Corsair Dominator PC2-8500C5D 2GB Matched pair @ 876MHz @ 5-5-5-15 (manually set, but rated SPD)

Now I can't push the FSB any higher, even with going higher than 1.55v (which I don't want to do, as it's already high enough for air imho), and I can't change the bios FSB:RAM ratio any higher.
I've also tried lowering multiplier to 388x9 (3.492GHz) but the system won't stay stable - regardless of the RAM speed.

In each situation, I've tried maxing out all the other voltages (vMCH, etc) but nothing makes any difference... The machine will post but won't boot into windows when I select 950MHz or 1050HMz (the 1050MHz limit I understand is with the chipset, but 950 shouldn't be a problem??)

Just an FYI- anything higher than pc6400 (800mhz) is not supported by our mb. There was a post earlier in the thread that showed several screenshots of different memory types, and how their SPD was broken down in CPU-Z. I'm not sure how the Corsair Dominators are split, but I know for my pair of Corsair 8500's, I don't have any breakdowns in CPU-Z; it only shows 533mhz 5-5-5-15.

From what I understand, people who can hit higher FSB have more selection in the memory breakdown, and can do more strange ratios stable. With my FSB at 385mhz(my max), I can only do 1:1 (770mhz). If I try the next selection down, I don't remember if I can't boot, or if I can, it's not stable..

Most important though: With this board, best speeds and timing is with 1:1!!

That doesn't quite make sense to me. I'm running my xms2 8500 at 1050 2:3, stable. IF I back my ratio off to 1:1 and tighten timings up as much as possible with these sticks (4-4-4-10) I loose performance over my current settings.

I don't quite understand the memory SPD breakdown in CPUz but I don't trust everything CPUz displays.

[Luis_GT]

Well, 1:1 @ 430FSB and running memory timings @ 3-3-3-4 Does actually work better than 1000 @ 4-4-4-8... for me at least and for some reason I can't get my memory to run 1000mhz on this board, so the comparison is between my old P5B deluxe and this.

Can you please post your settings (multiplier x fsb#:1050) ? I'm curious if I would be able to hit them with my mem so I could do some benchmarks, once I get my mem back from Corsair, of course.

In all the testing I did with my mem/fsb ratios, nothing was as efficient as 1:1.

edit: need to know multiplier too plz.

There's a "Ghetto Mod" for the P5WD2. I'd like to know if this works for the P5W DH as well. A simple pencil mod would be nice for the vdroop.

Anybody know if this works with the P5W DH???

Kyosen ghetto mod works very well. Resistor measures about 50Kohm unmodded. Found my 'sweet-point' to be aprox 21Kohm.

[iadstudio]

Here's what I just posted for the extremeoverclocking.com database. It's got timings, memory ratio, fsb. I have the vmch at 1.65 and vfsb at 1.4.

I suppose If I had some sticks that could do 700mhz with CL3 that might best my current settings but these sticks won't go CL3 stable.

Not ideal I know but the best my parts will do, I think.

"Locked" Multipliers on Extreme Edition CPUs Issue Resolution:

Since BIOS v1602 Asus introduced us a new "feature" from their BIOS Coders ( sigh ), they managed to bug their BIOS so much as never before!
Now every Extreme Edition CPU owner has the "default" range of multipliers available [ 6-11 for X6800, 6-10 for QX6700 ].
BIOS v1602, v1707, v1801, v1803, v1804 suffer from this issue.

To get your multipliers back you need to go back to any previous BIOS release { earlier than 1602 ofcourse ) performing a full eeprom flash [ the Asus utils do not perform a full eeprom flash ]

Sounds like we have the same settings almost. 1.5v in bios gives me 1.50-1.53v in speedfan. No multimeter here either.

Have you replaced the NB and SB TIM? I have a extreme spirit II on the SB and a 40mm fan on the NB with those metal covers taken off. Unfortunately you have to void the warranty and replace the TIM with Arctic Silver and loose the covers. That alone could give you a 10-15c temp drop on the NB.

Use the touch test... if the NB is too hot to hold your finger on it for 5-10 sec then you definately need to cool it. I would assume maximum cooling precautions should be taken either way if you want to really push the system.

Also, I have my memory at 2:3. This memory doesn't like tight timings so the extra bandwidth is helpful since you can't really tighten timings too much.

Edit: I just saw that you have 4gb of memory. Is that true? If so that could be limiting you memory multiplier but I would still try it.


I've just looked at the vCore as reported by speedfan, and it holds steady at about 1.52v (1.55 in BIOS).

The NB and SB are both untouched, and I've not modified any part of the mobo. I could put some AS5 on both, and removing the heatsinks+heatpipe for application looks pretty easy (do you think?).

I'm only running 2x1gb RAM sticks - the Corsair model number is correct, but it's not 2x2048MB, it's just the "TWIN2X" range!


Hmm thats odd. I can reach 400 FSB completely stable, but at 415 I can't even post. I'd just say make sure you have everything disabled you don't need that could be interfering with your OC. Checkout Kastaar's bios if you'd like, he made it to 440 FSB.

With regards to BIOS settings, yes I have everything like hyperpath, etc. disabled - infact all apart from the hardware DEP (I presume that makes no difference??).

I'm considering selling/buying my C2D in an attempt to get a newer revision - where will I find the week build of my current processor (the batch number is L627A085)?

I would at least pull the SB and NB off and replace the TIM with Arctic Silver5 or something as long as it's not the ASUS stuff. IF you don't want to void the warranty just be careful not to mess the covers up. Taking the covers off will help quite a bit though.

Not sure if this is your specific problem but it helped me. I have an early week like yours (mine is a week 24 I think) and I too have a hard time reaching the higher OC's without going nuclear on the vcore. I have a 2 year warranty on the CPU so I'm going to wait until the end of my warranty to turn it in.

[fadden]

Has anyone had trouble with heat sinks using the standard snap-in mounts on this MB?

I have a quad-core QX6700 and a CoolerMaster Hyper TX. (I bought an OEM chip without a heat sink.) I've been having some issues and I think they're heat related.

Backing up a bit: when I first put the system together, I wasn't planning to OC anything, so I used the thermal pad that came with the heat sink. A few weeks later the computer would stall on startup -- after a couple of seconds you'd hear a fan kick into high gear, and nothing further would happen.

I thought it might be the motherboard shutting down the system because of excessive heat, so yesterday I detached the heat sink, cleaned everything, applied some Arctic Silver, and remounted it. It immediately booted with no problems. Temperatures went from 70C idle / 90C gaming to 52C/70C.

(My theory is that the bursts of heat soften the thermal grease, improving the conductivity, so it needed to try to start up a couple of times before it really got going. Until then, the thermometer just shut the CPU down a second or two into POST.)

Today it had some trouble booting, and I'm seeing 57C/80C. I'm wondering if the heat sink is sagging in its mount and pulling away from the MB.

Has anyone else seen this sort of issue with a P5W DH Deluxe?

Any suggestions on heat sinks if this just doesn't work out? I prefer the snap-in kind, since I won't have to pull the system apart to attach a backplate, but I'm starting to wonder if that's workable with this MB.

My apologies if this question is a little low-powered for this forum. :-) I had the opposite problem with a different LGA775 MB -- I had to press insanely hard to get the pegs to set -- but that system hasn't had any problems.

No, not the 'break-some-pencil lead-mod' . Kyosen has another mod, involving soldering a resistor - pencil it instead.

PW5DH and P5WD2 uses the same vreg-chip if I remember right.

Yup, us early adopters got shafted...do you find that you can get a moderate overclock at low vcore, but then it seems to plateau...and you need HUGE voltage for any gains?

If you mean 3ghz stock volts (1.325) (real volts (1.375 bios)) then yeah, 3.2ghz = 1.475 bios/ 1.411 actual, 3.5ghz = 1.59v actual

No t Exactly how mine turned out but pretty close. I've gotten mine stable at 1.53v actual but the 3gh to 3.3ghz jump for me was 1.325v to 1.5v.

Just curious, does the droop normally get larger the more volts you push?

Hi. I'd uninstall AIBooster right now and just scrap that worthless software. You can get temperature/voltage information from Speedfan.

Does your Adaptec card work like it should and not throw up any errors in any other software?

[.. clip ..]
I'm considering selling/buying my C2D in an attempt to get a newer revision - where will I find the week build of my current processor (the batch number is L627A085)?

Removing the current heatsinks and putting AS5 is a good idea. If you want to replace the stock heatsinks with recommendations in lawry's first post, that's even better. My only warning is be gentle/careful with the hooks that hold the NB in place, cause they're only soldered in, and very poorly at that.

For week of your chip, it's the 3rd/4th character over. L627A -> week 27 revision A. Anything A and under week 32 is iffy on hitting high clocks without serious extreme cooling and a TON of voltage. If you can, try to get a week 32+ B, since they seem to require the least amount of voltage and aren't walled as low as the chips the earlier one are.

Best of luck.

[nickfd]

I'd say test every other piece of hardware in your box before you think its the board. Like i mentioned in an earlier post, my decaying performance ended up being one of my sticks of memory rather than the board or the CPU.

Between where the yellow and orange cable is soldered. (It's a resistor there - Kyosen removed it in the picture). Pencil it to aprox 25 Kohm - measure idle voltage and load voltage. If droop under load is observed, try 20 Kohm.

Not sure why you're having problems with the memory ratio but if you can't reach 2:3 with your clock try 4:5. From What I've heard, that's the preferred ratio if you're not at 1:1. IF your clock is 385 then 4:5 might be 850ish? I wouldn't sacrifice CPU speed for memory, at least not with these chips. Try 435x8 (if you can reach that) and go with 1:1 or 4:5 before you back your chip down.

This was my first OC experience so I though the Corsair8500 was the best choice but I was wrong. If I could do it over I would get some ultra low latence pc2 6400 sticks. Can't complain too much though, I get a 14.6 sec super pi 1m with my current settings. Gotta love the P5W !!! Clock for clock it (and a few other ASUS 965/975 boards) really does outperform most boards.

It won't be easy for me but I got warranty from Microcenter (retailer) when I bought the chip. I have about a year and a half to figure out how to fry the chip within the terms of my aftermerket warranty. I'm pretty sure I can just start it up without the heatsink and call it a day. I'll get a gift card for the original purchase price and put that towards whatever's out then.

I wonder if the 45nm chips will work on this board?:rolleyes:

You need the pressure of a heatsink to make LGA775 cpu's work.
If you simply take off the heatsink, the cpu won't start.
Overvolting is possible, but if your luck runs out, your northbridge will die too...

[Shpoon]

If you mean 3ghz stock volts (1.325) (real volts (1.375 bios)) then yeah, 3.2ghz = 1.475 bios/ 1.411 actual, 3.5ghz = 1.59v actual

I can get 3.1 @1.325 stable, 1.3125 (BIOS all) semi-stable (crashes doing the weirdest things).

3.2+ needs an insane amount...can't even reach 3.3....at 1.55V, it doesn't even post...

[iadstudio]

To be honest, I have no idea how to go about it. I could have gotten the accidental damage warranty for $300+ and it would be no questions asked. Instead I got the $99 Bronze plan that covers product failure.

If one were so inclined to facilitate product failure NOT due to operator negligence, how would one do that? I don't think microcenter will scrutinize the claim as much as Intel would but it has to look reasonable.

I'd rather not fry the mobo to but if it happens, ooh well. As long as it happens after I fry the CPU.

Between where the yellow and orange cable is soldered. (It's a resistor there - Kyosen removed it in the picture). Pencil it to aprox 25 Kohm - measure idle voltage and load voltage. If droop under load is observed, try 20 Kohm.

Thanks man, didn't completely get rid of the droop, but I got the load and idle to be with in .01v, which is all that matters. :thumbsup:

Pics of your mobo with the pencil mod. I want to do the same and since you've successfully done it...

...less chance for me to screw up if I have pics. I'm a complete noob to OCing and this'll be my first voltage mod.

[triggerc]

Hope you don't mind the crude drawing

the resistor you pencil is the one circled in yellow, the lower of the two resistors in the set. The resistor is located around the area in between the upper right mounting hole for the cpu and the top middle mounting hole for the motherboard.

I would sharpen a pencil and blow it with some compressed air after every couple strokes to make sure that the only graphite on there are the ones staying on.

HS without TIM?

Naaah, cpu runs fine with HS without TIM, just 10 or 15°C hotter.
And if you stop the HS-fan, the cpu will simply halt without destroying itself...

Just play it fair man, sell the cpu to someone who wants to use it stock or mildly overclocked...

[Phoenix_TT]

Hi. I'd uninstall AIBooster right now and just scrap that worthless software. You can get temperature/voltage information from Speedfan.

Does your Adaptec card work like it should and not throw up any errors in any other software?

Speedfan will show the CPU Vcore (and seems to be accurate), however for temps it's best to use coretemp or TAT.

[Phoenix_TT]

Blimey that seems worse than mine. I have a wk 24a ! What are your BIOS settings ?

Over the weekend I got mine 9 hours Orthos stable (CPU and Mem test, blend?) using CPU Vcore of 1.55V (actual 1.52-1.53) and FSB of 389 (3.5Ghz). Memory at 2.1V. After 9 and bit hours Windows blue screened with MACHINE_CHECK_EXCEPTION, but I never use my PC for 9 hours!

What hardness of pencil did you use?......how many strokes?

[Krusty]

Hi, you've actually just run into a problem that windows xp has that's inherent to how it operates as an operating system. It was not designed to run as a symmetric multiprocessing (SMP) OS, but rather single core, single thread. As Intel released their hyperthreading technology, windows modified its code to allow for this, and tweaked it slightly to fit our dual and quad core environments of today. What you see in the OS is what you get, unfortunately.

I'm not sure the back-end logic and implementation of SMP in Vista, or if it will handle symmetrical processing better, but you have to be also using an application that is designed for it as well. All of the large, workstation class applications do have support for multiple cores, even running on XP (like Adobe Premiere, 3d Studio, etc), but you won't be getting as much benefit as you would on a similarly spec'd unix based workstation that was designed from the ground up with SMP in mind.

I know MS was going this route, as were all the game developers, so I'm sure we'll see better utilization and better scaling of games and applications upon multiple cores in the near future.

So in the meantime, if you want to only stress one core at a time, you'll have to manually set affinity in your task manager. However, from what benchmarking I've done in various applications, forcing an application to use only one of the two cores actually cuts your overall processing potential in half. This may not be true for all applications, but just from what I've seen.

Thanks for the explanation. I wonder does Linux handle multi-core processor better?

[Zeus]

I just did the mod and the droop has got a lot less. :)

Prior to the mod, i saw CPU-Z reporting Vcore going down as low as 1.392V while i had set it to 1.4375V in bios.

This was when running Orthos small fft's.

After i did the mod, i set Vcore to 1.425V (so, a tad lower) and now the lowest CPU-Z reports is 1.408V.

So prior to the mod i needed 1.4375V in bios to get Orthos stable at 3.6GHz due to Vdroop, now i can do the same with 1.425V.

It's just not that the Vcore doesn't fluctuate anymore, it still does but it does not get as low as it used to.

I see there's some misconception about the Vdroop pencil mod, let me explane how to do it:

Locate the resistor in the picture, it's somewhere at the northside of the board.
Take a Digital multimeter and measure resistance of this resistor, mine was 50Kohms.
Just take a soft pencil and stroke the resistor a number of times, now measure again.
Repeat untill it reads 25Kohms.

Make sure there's no graphite particles elsewhere on the board before firing up.

This mod is done at your own risk.

Sit back and enjoy.

Glad it worked! But you haven't found your mobos 'sweet-point' yet. Mine dosen't droop at all running Orthos. The only stresstest where I notice droop is TAT. Try lower it to about 20Kohm.

what is the real vcore when i set the vcore in bios to 1.485?
i have readed that the real vcore is at 1.485 -> 1.43V .. is that right ??

I have my droop pretty well under control now, but i've no idea how to use my DMM to measure resistance. Did you put both probes on the resistor or just one?

[Zeus]

Put the probes on both sides of the resistor and select >50Kohm on your dmm.
Put the probes on the silver parts right on the edges of the resistor.

[triggerc]

and i do this with the system off but psu on right?

[Zeus]

Everything off!!

Do not poke around with the probes with the PSU turned on.

You'd best pull the powercord.

[triggerc]

alright, i just took a look and i'm getting 18 or so k ohms, maybe that's a little too low?

[Zeus]

I dunno, haven't tried that low.

Take a q-tip and remove some graphite if you want it a bit higher.

Hi,

You can actually run 4 sata hdd's off your intel ICH7 southbridge, and I would highly recommend this over trying to get the JMicron and/or the SiliconImage crap(ez-backup) working.

Plug your drives into SATA 1 (red), SATA 3(actually#2 black), SATA 4 (black), remove the jumpers off the ez-backup area, and plug into the right yellow ez-raid port (actually SATA2). I don't remember the physical marking of the right ez-raid port, so please forgive me.

If you have the jumpers off and boot with the drive attached, you'll see it in the list of the ICH7 area as your box posts, if it's in the wrong one, you won't see anything. Also, you may want to set the DH Features Change option in the bios to Enabled when you take out the jumper and attach the drive to have it tell the SiliconImage crap to turn off.

Bingo. You have 4 hdds on ICH7 and can turn off JMicron in bios.

That's a great tip if it really works. One of my biggest gripes with this board's design is the use of the SiliconImage port multiplier on the ICH7R. Have you verified that it is really turned off and not running in RAID 1 (which I believe the manual says to use if you are running a single drive on an EZ port)? Does NCQ work on a drive connected this way?

[BenchZowner]

I'll have the site ready tomorrow. and will I publish the related article and Asus's Tech Support evaluation results article.

Is anyone using a FireWire hard drive on this board's FireWire controller? I have and admittedly cheap FireWire/USB to IDE enclosure. I was getting delayed write failures and other error messages and lost a lot of data. Switching to a USB 2.0 connection for the enclosure resulted in better performance and no more errors. Now I've installed a PCI FireWire card and went back to using the drive enclosure's FireWire connection with none of the previous problems.

I wonder if my MB's firewire controller is bad or if it could simply be the FireWire to IDE chipset and my motherboard don't get along.

[iadstudio]

I use a firewire backup drive and it works fine. Nice transfer rates too. I actually ran out of USB. I only have SATA drives in my machine though. Did you say you have IDE? Shouldn't matter which type is in the enclosure though.

I've seen delayed write failures occur frequently with cheap USB enclosures. In most cases, if you change only one component (either the computer/motherboard, the usb/fw enclosure, or the drive that lives in the enclosure) the problem ceases.

Case in point: I have a cheap USB enclosure in which I installed an old 200GB Maxtor drive. When I tried to use it with my laptop I'd get DW failures. I replaced the drive with another Maxtor 200GB (identical model) and it functioned fine. Fearing that the first drive must be failing, I installed it into a different USB enclosure and tried it with the laptop... it worked fine.

During my troubleshooting of the issue I discovered that compatibility issues between drive, controller and interface can occur, especially with cheaper chips.

I know that you are using FW instead of USB but I believe the issue is the same as it comes back to the IDE controller chip. So, no, I don't think it's your firewire port.

Perhaps increase the MCH v to 1.65. Also what memory do you have ? What's your cooling like and do you have an aftermarket HSF ? You may need to pump more CPU vcore, if you are prepared to do so, but make sure you have some decent cooling.

[nickfd]

Not sure why you're having problems with the memory ratio but if you can't reach 2:3 with your clock try 4:5. From What I've heard, that's the preferred ratio if you're not at 1:1. IF your clock is 385 then 4:5 might be 850ish? I wouldn't sacrifice CPU speed for memory, at least not with these chips. Try 435x8 (if you can reach that) and go with 1:1 or 4:5 before you back your chip down.

This was my first OC experience so I though the Corsair8500 was the best choice but I was wrong. If I could do it over I would get some ultra low latence pc2 6400 sticks. Can't complain too much though, I get a 14.6 sec super pi 1m with my current settings. Gotta love the P5W !!! Clock for clock it (and a few other ASUS 965/975 boards) really does outperform most boards.

Thx for the info. I am able to reach the same ~3500mhz wall no matter if I use 8x or 9x, so I'll do that when my mem arrives. The biggest thing of importance for me is gaming at the moment, since my video-production/dvd-authoring is once in a blue-moon kind of thing, so I'll 3dmark06 it and see how it goes.

Appreciate it!

If you remove all the jumpers for the ez-raid siliconimage controller, it will completely pass through the one port will act exactly as an ICH7 port. You will get NCQ and everything that you get as if you were plugged into an ICH7 port. However, if you force the jumpers to "big"(bug) mode, it will show up as "External Drive" and I'm not sure whether or not it will have NCQ.

[nickfd]

:confused: :confused: :confused:

You can see just in the past few pages several discussions about this topic alone. It's related to vdroop, and it varies depending on load, how much voltage you're putting into the vcore, and some magic formula that we have no idea.

If you want to resolve it, you can solder in a potentiometer/resister and follow the instructions, or do the pencilmod from a few pages prior.

I use a firewire backup drive and it works fine. Nice transfer rates too. I actually ran out of USB. I only have SATA drives in my machine though. Did you say you have IDE? Shouldn't matter which type is in the enclosure though.

Yeah, it's IDE and I've had the same issues with different drives installed in the enclosure.

I've seen delayed write failures occur frequently with cheap USB enclosures. In most cases, if you change only one component (either the computer/motherboard, the usb/fw enclosure, or the drive that lives in the enclosure) the problem ceases.

Case in point: I have a cheap USB enclosure in which I installed an old 200GB Maxtor drive. When I tried to use it with my laptop I'd get DW failures.

I know that you are using FW instead of USB but I believe the issue is the same as it comes back to the IDE controller chip. So, no, I don't think it's your firewire port.

Thanks for the info. I tried switching drives and the second drive did the same thing. I thought maybe it was the cheap power supply that came with the cheap enclosure, so I tried powering the drive from the PC's PSU but that didn't help. USB works great on this same enclosure, though, and firewire works great on this enclosure using my PCI firewire board, so I was leaning heavily toward blaming the motherboard. I was hoping it wasn't totally broken, just not as robust at handling flakey firewire-ide bridges and I guess maybe that's the case, which is good news (relatively speaking).

My firewire card has a 4-pin molex power connector (which I have hooked up). I wonder if it could be a power issue? Maybe I should try running without the power connection to see what happens.

Edit:

Tried without the power connection to my firewire PCI card. The card still worked but the drive didn't get detected at all, so I suspect that it may be a lack of adequate power on the built-in firewire port. I know this firewire-ide board gets power via the firewire port, because even with its power supply disconnected it powers up and is detected.

Based on what I've read over the past few months of owning this board, any configuration in which the SIL is alive you get no NCQ or SMART. That's great news about enabling the direct ICH7 port connection by removing all jumpers, though.

Update:

I just had to try it, so I removed the jumper and moved the second drive in my array to the second EZ port and it booted with NCQ working on both drives, so thanks again for the tip. One of my complaints about this board is no more.

Hahah, sorry, I didn't mean to type "PC", thanks :p:

I'll take some pictures later on of my bios settings.

(If you're wondering about the ram, it was the same price as the PC6400 after rebate and price match, I AM NOT rich enough to buy it normally ;))

Hey Shpoon,

I saw an earlier post of yours with some of your settings, and pasted them here. I would surely use 1.65 for your MCH, and with pc8000/pc8500 memory, you know you need 2.2 vdimm, right? That may be your problem, so please try at least 2.2 and don't be afraid to go up to 2.4 vdimm with it for testing purposes.

I'd also like to know your temperatures on the cores while idle and in torture mode (prime95/orthos) when you're pushing voltage. You say you can't even reach 3.3v at 1.55 vcore, but have you tried 1.60+ vcore? I need to push that much voltage to hit any reasonable clock, and my coretemps are okay.

To run 2 or more instances of SuperPi altogether, you need to run each instance from a different folder.

Just got the P5W DH and in process of installing it. Saw on a previous post that there is a problem with updating Win XP if you have a Creative X-FI installed. Has this problem been resolved with the later (latest) BIOS flashes or what?

Also, MB manual states that the board does not recognize a SATA drive untill XP SP1 is installed. Does this mean you have to istall Windows on an IDE drive first and then to use a SATA drive for boot drive you clone the IDE drive to a SATA drive?

Any other quirks or tricks I need to know?

Thanks for any help.

[iadstudio]

I did the pencil mod to controll the vdroop I get on this board and it worked! Thanks guys for all the instruction/pictures. I have my board set to 1.5375 and it would droop to 1.49-5v. Now it stays between 1.54 and 1.52. I even squeaked an extra 50mhz out of it now!

I can't get much higher though because it seems that when I raise the voltage the droop increases a bit. Either way, thanks for the help! can't complain about the results.

One question though, what happens if I put too much graphite on the resistor?

[bellx1]

i have an issue with the setup im trying to run. the issue is that i have 2 seagate 120gb drives i want to use as storage, but vista ultimate see's them as one combined drive that is unreadable and unallocated and in disk management all the options to format/partition/etc are greyed out. whne i look at the properties it has the disk labeled the same way i had them about a year ago when they were raided together! is there something i need to change to get them to be seen as individiual drives? i have tried every combo of things i can think of, its drivin me nuts lol

right now i have AHCI selected in bios. on the red adapter is my raptor 150gb with vista, on the black next to the red is a wd 500gb backup drive. on the next black is a 120gb seagate, and on the ezraid 1 is the other seagate 120gb. i have removed both jumpers from the ezraid currently, but have tried this in all the jumper configs trying to get SOMETHING to let me access the drives. the only thing that would let me get on the drives is using the jmicron, but i can only see the one drive on jmicron and not the 2nd drive on either the black or orange connectors when i do this. the raptor and wd 500gb always show up just as they should.

is this because i have ahci enabled? does something in the mbr (i dont even know what that is really lol) of the seagates need changed?

help please:eek:

[jkresh]

bellx1 have you tried booting with only 1 drive plugged in? Also you said they were raided last year, have you used them in a non raid situation since then or were they in raid last time you used them?

[bellx1]

yes, i have tried it with just the raptor running vista and one seagate only. i've tried the seagate on each of the other SATA spots (blacks and oranges) and still the same thing.
i had them running as individual storage drives on my windows xp (1 on each black adapter) until i switched to AHCI and put vista on this computer.
apparently the ez-backup mirrored my drives too somewhere in me mixing the adapters to make this work, because when i hooked them up to the jmicron the 2 drives (that previously had completely different things backed up on them) became 2 copies of 1 drive. (unfortunately it mirrored my drive of movies/crap and i lost my otehr drive of documents, mp3s, programs :( )

[Alfieg]

with both vista and xp the windows bar scrolls 11 times. i have an e6600 on p5w-dh with 2xraptor x in raid 0 powered by corsair hx620. i have tried all the diferent bios's to no avail. sometimes and i never know how i remove a drive say and it boots in a second, but not always. jmicron is disabled. running a 500gb sata drive on ich7 with the raid + 2x pata dvd on ide channel. i have tried almost everything apart from changing opticals to cable select as i suspect it's a random i/0 problem. is anyone else finding that whatever boot and drive configs they use windows boots real slow. hope someone has the answer.

In device manager disable everything you don't use, and if you're only using 1 ide drive on a channel, click properties and instead of Auto Detection, change them to Not Installed so on boot it doesn't search for ide drives. Also in bios change the ide options to Not Installed for unused ports.

Hi. I actually bought and installed my x-fi after I had my system up and running, and didn't have any problems. You will surely want to download the latest driver off Creative's site, and use at least bios 1707 (unless we get this new 1901 with 1333fsb and its stable).

What the manual means regarding SATA is that you will have to use a slipstreamed copy of Windows with SP2 to avoid having issues. I'm not sure whether or not anyone had any problems with the vanilla XP, but when I did my load, I used a slipstreamed copy with all patches back to 11/2006. No problems!

For quirks and tricks, spend a week and go through the thread. :eek:

^-- When you create arrays, yes, it does write to the MBR and tags the disk with the type of array that it's assigned to.

If you can, set your BIOS to RAID, not AHCI, and from the Intel Disk Config that comes up when you POST, delete the drives from whatever array they're showing. You can run Non-Member disks in RAID mode and have them be JBOD just fine, with full AHCI/NCQ support.

Also be sure you have the latest version of the Intel Storage Matrix drivers inside windows. You didn't mention if you did or not, but it's important.

Lastly, if you still can't get it to work and modify the drives, download a copy of SystemRescueCD (http://www.sysresccd.org/Main_Page), and use gparted when you boot into the linux. You can manipulate all drives/filesystems from here, but you may have to know some linux to get around.

Best of luck!

Hey Rob, I noticed your 3dmark06 score. Wicked man. Could you give the breakdown of the CPU/GPU/Shader scores (or whatever it is when you look at detail on their webpage).

I know our 8800gtx's are being bottlenecked by the CPU, but I find it hard to believe by *that* much. My e6600 (@3.5ghz) + 8800gtx is just over 11,200 in 3dmark06. If the CPU helps to hit a 19,000, I'm going to have to catch a deal on one and fleabay my melon crap cpu. I need better performance in Vanguard! :D

Hi Nickfd,

Score achieved with EVGA 680, 8800 GTX (SLi) @ 690/2100 and QX 6700 @ 3.943, all cooled with an Overklokk built Waterchiller for CPU and GPU's. However, got bored with the EVGA MOBO and bought P5W DH Deluxe which overklokk modified according to the recipe on first page. He also rebuilt the waterchiller into a singel stager phase as well as I got hold of a better sample QX6700. Present CPU runs 3dMark06 @ 4.5 which gives a CPU score of 6.400 or thereabout. (CPU tested 3dMark06 stabile over 5.1 GHz on LN2... :D) Just waiting for those R600 cards in crossfire now so that I can pass 21.500... :p:

You can use any of the previously released BIOS versions to use the upwards multipliers with X/QX CPUs.
If you've flashed to 1707 or any newer version, you need to flash back by performing a full eeprom flash.

thanks! that was exactly it. this actually occurred to me on the drive to school today that i had never reset the drives from the raid array back to non-raid status. i disconnected all drives, placed the seagates on sata 1 and 3, changed bios to raid, entered the intel manager with ctrl+I, reset them, put bios back to AHCI and my raptor back to sata 1, wd500gb to sata3, seagate to sata 4 and seagate to ez-backup 1 and now it shows just as it should with each seagate being an individual drive. :banana: somtimes, im such a tard lol

Thx,

Tried all new BIOS's but no open multiplier for my QX6700 after 1601. I normally use Asus EZ-Flash utility (within BIOS) to upgrade BIOS but BIOS 1601 - for some reason - does not allow this procedure. Yes there is a f*** up somewhere. Consequently, I have to use the Windows Update Utility to upgrade BIOS and everytime I pray (yes, just like we pray to our Lord Jesus) that the newer BIOS will allow me to flash back to 1601 (using EZ-Flash utility) if I find that the new BIOS does not have open multiplier for the QX6700... Our soules and gratitude to ASUS... May the Lord be mercyful... :slapass:

You should be able to flashback to 1601 using the AFUDOS utility.
If you're more like...me ( no FDD around since...2004 I think :D ) you can use a bootable flash cd ( bootdisk.com for ISO image AFAIR ).
I don't remember the full flash switch for AFUDOS atm.

[gritty]

Nick, thank you for the reply. Been reading forum for a few weeks already. That is where I came up with my questions, hoping that there were some fixes, especially in BIOS from Asus so I would not have to do anything special. I may have missed some things as there is an awful lot of stuff here. Sure is a lot harder making a new computer than a few years ago when all you had to do was install the parts and load the OS.

g'day...

Well I've tried but can't find any retailer who sells any E6700s that's a better sample than mine (I'm after a week 32+), but to make matters worse this week the pc has been going skitty!

Essentially repeated BSODs in XP reporting some kernel exception, then I got a different one with IRQL_NOT_LESS_OR_EQUAL error. I've had the latter exception before (on a P4C800-E when o/cing), but I've not had the sinister sounding kernel errors before. I've checked with the windows debugging tools and ALL of the bsods appear to be related specifically to kernel processes which again I've not seen before (on the P4C it was always a random process/driver). Now to me it seems that my windows kernel could somehow have been corrupted (no idea how), yet when I turn my RAM speed down from 875MHz to 700MHz, the problem appears to go away (I found this by originally going back to stock CPU speed and working my way up).

This all seems a bit odd, seen as I've been running the machine on stable settings for months - does anybody recognize this apparent hardware degredation? I do remember "degredation" of sorts being mentioned in this post, but that was relating to FSB. I'm planning to install XP again on a seperate drive and testing, but I think that the RAM speed solution shows that the mobo is goosed, but no idea why!

Anybody got ideas?

Cheers :)

Sounds a lot like my problems. I have the same basic setup as you, corsair pc2 8500C5, e6700 and p5w. I had to pull my memory back to 1:1 at 760mhz and the problem went away. I managed to get a 2:3 memory ratio stable for months (1020 4-4-4-10) and then one day after installing some new led fans the system went heywire!

I pulled the fans off the mobo and have them directly into the PSU and it seemed to pacify the issue. Could I have hastened the deterioration of the board due to over volting the memory and fans?

I've since done a pencil mod to calm down the vdroop and squeezed 50mhz more out but my memory will no longer run stable at anything more than 4:5 and even that is a stretch some times. I also can't boot anything over 382fsb so I think the board has been tapped out. When I have more time I'll play with the memory more but I don't have time to right now. I have a sinking suspicion that this memory really suffers when it's been given 2.4v to achieve lower latencies or it could be the memory slot on the mobo. When memtest showed the memory failing it was always the same slot.

Sound familiar?

[iadstudio]

...when I turn my RAM speed down from 875MHz to 700MHz, the problem appears to go away...

And that's too bad because I found the extra bandwidth (as long as you can maintain low latencys) really helps. It might be time for us to bite the bullet and invest in some CL3 pc2 6400. CL2 at 700mhz would rock!!!

[Nmbr1Ballr]

Right now I think I have hit a wall. I am at 3.6ghz @ 1.5375volts in bios. Temps are at 57ºC at load. I try and run 3.8ghz @ 1.65volts and it gets to the point where normally that windows screen would come up where the blue bar goes across the bottom of your screen a couple times, but it just sits there at a black screen. I do have an A chip also. Any ideas? Also if I want to run my ram faster and in bios it lets me choose from 800mhz next is 1000mhz, what if I want like 850 or 900? Can I do that and how?

[BulldogPO]

Where is info how to do this pencil vdroop mod?

[LV426]

Hi. I have a weird problem with my P5W DH Deluxe, bios 1602. The rest of my setup: E6600 @3.2GHz (8*400), Zalman CNPS9500 LED, 2x1GB Kingston Value 800MHz DDR2, ASUS GF 7950GT 512MB, 2x300GB Seagate 7200.8 @RAID0, SB Audigy 2, Corsair 520W PSU.

When I first set up my rig, I tested it both at default speed and overclocked @3.2 (8*400). For testing I used several hours of 3DMark, Orthos Prime (x2), games, video encoding etc.
It worked perfectly @400*8 for about two months, temps were ok (and still are), never above 62 C under full load.

Now I'm experiencing lockups, usually after about 5-10 minutes under full load, and I have to hit the reset button. After that, the mobo usually won’t boot so I have to turn it off and back on again. It then says something like “overclock failed, enter setup”. If I just try the previous settings in bios (just hit F10 and save) it almost always locks up again, however if I reset the multiplier to 9 (default) it boots at 3.6GHz!!! at the same voltage, and I enter bios setup again, lower the multi to 8, it then boots and works normaly at 3.2 GHz. Until the next time it locks up.

I’ve tried upping voltages without success (temps are not too high, I also tried running with case open), so I’m guessing it has to do something with the multiplier, because it runs normally @ 9x and lower FSB.
It’s like it locks up just because multilpier has been changed from the default value (like the mobo doesn’t “like” that), however I haven’t seen anyone else having such a problem. I must say again, it used to work normally before, at same voltages, temps, settings.

Any ideas?

Thanks.

p.s. would you recommend the latest bios 1707?

[OneyedK]

:confused: I notice that several users are commenting about a decay in performance...
Would you guys give details about cooling pse?

After one month, my system was 24/7 f@h+f@hgpu stable @ 400x8. (bought the rig in august '06)
cpu: E6400/cnps9500cu
nb: MCX159cu
sb: lapped stockcooler with 120mm silent papst that blows over it in the direction of the intake of the X1900XTX stockcooler.
mem: 1:1, no extra cooling, 2*5400UL 512MB before, 4*Platinum Alpha VX 1GB now

Maybe not so extreme, but it's running flawless for all those months.
I don't like to compromise on stability, so I always revert to these settings.
System is bencheable at 440MHz, but hell, it's only aircooling and it take a lot of extra airflow to keep it on 440...
The fans are on the mobo, that doesn't give me any problems.
I have a rheobus lying around, but I still have to open the blister ;-)

I'm using a Zalman CNPS9500 HSF for the cpu (on AS5), set to a relatively low speed speed, and three antec 120mm fans that came with the case (1 on rear, 1 on top, 1 on front) again all set to a low setting. The airflow seems good enough to me!

P.S Just bought a new P5W... will fit it and do some testing later, and I'll post with updates :)

(CPU tested 3dMark06 stabile over 5.1 GHz on LN2... :D) Just waiting for those R600 cards in crossfire now so that I can pass 21.500... :p:

Hey Rob, I got this when I tried to take the futuremark url: The project id is not valid - please check the URL. Can you double check to see that it's correct please?

So in moving to the p5w dh over the 680i, you lost your sli, right? And right now you're only using one 8800gtx, or did you find hacked drivers to use sli on this board? (Are there high end detonator 97+.xx 8800 series sli hacked drivers yet btw?)

Can you also provide some links on your new phase cooling? I'm looking into some peltier+water cooling solutions, but since I'm wanting to drop 300$+ on subzero cooling, maybe I should look at phase.. I don't know much about the different types (doing slow research atm..), and I won't go peltier/phase until I find a good board/combo of oc'ing a quadcore.

I know quadcore is the way I want to go with the processing power I need, but I'm not too happy with current chipset offerings in oc'ing the quadcore atm.

Thanks man!

Lost Sli turning from EVGA 680i to P5W DH Deluxe and only have one 8800 GTX at the moment; eagerly awaiting the R600 cards. But do like the stability provided by the P5W DH compared to the 680i. That was one crappy MOBO... Have no problems recommending the current setup with a QX6700 but have to admit that I am awaiting some better BIOS'... In need for more RAM tweakings and open multi for X6800/QX 6700. If you just want one GPU, you can also go with the Commando and the 965 chipset...

Hey... I just built my rig w/ the E6600 and P5W DH Deluxe using the Tuniq Tower 120 and of course G. Skill 2GBHZ memory... I am currently using the 30% Overclock profile provided by Asus... I listened to larrywild's post and currently running BIOS 1707...

The 30% overclocking profile oc'd my machine to an amazing 3.11GHZ...but I want to be able to do at least 3.5-3.6 since reading through these threads, people said that the E6600 can do 3.8 like nothing... Can anyone help a n00b out on how to overclock manually (w/out using asus's ai booster or profiles) and if you could post your settings... Thank you! Graetly appreciated!

Pencil the top resistor.

[nickfd]

Right now I think I have hit a wall. I am at 3.6ghz @ 1.5375volts in bios. Temps are at 57ºC at load. I try and run 3.8ghz @ 1.65volts and it gets to the point where normally that windows screen would come up where the blue bar goes across the bottom of your screen a couple times, but it just sits there at a black screen. I do have an A chip also. Any ideas? Also if I want to run my ram faster and in bios it lets me choose from 800mhz next is 1000mhz, what if I want like 850 or 900? Can I do that and how?

Just be glad you can do 400fsb with your A chip (garbage crap melon cpu :mad: ). You're probably limited by cpu wall. Many of us cant do more than 360-380ish with our early week A's.

Hi. I have a weird problem with my P5W DH Deluxe, bios 1602. The rest of my setup: E6600 @3.2GHz (8*400), Zalman CNPS9500 LED, 2x1GB Kingston Value 800MHz DDR2, ASUS GF 7950GT 512MB, 2x300GB Seagate 7200.8 @RAID0, SB Audigy 2, Corsair 520W PSU.

When I first set up my rig, I tested it both at default speed and overclocked @3.2 (8*400). For testing I used several hours of 3DMark, Orthos Prime (x2), games, video encoding etc.
It worked perfectly @400*8 for about two months, temps were ok (and still are), never above 62 C under full load.

Now I'm experiencing lockups, usually after about 5-10 minutes under full load, and I have to hit the reset button. After that, the mobo usually won’t boot so I have to turn it off and back on again. It then says something like “overclock failed, enter setup”. If I just try the previous settings in bios (just hit F10 and save) it almost always locks up again, however if I reset the multiplier to 9 (default) it boots at 3.6GHz!!! at the same voltage, and I enter bios setup again, lower the multi to 8, it then boots and works normaly at 3.2 GHz. Until the next time it locks up.

I’ve tried upping voltages without success (temps are not too high, I also tried running with case open), so I’m guessing it has to do something with the multiplier, because it runs normally @ 9x and lower FSB.
It’s like it locks up just because multilpier has been changed from the default value (like the mobo doesn’t “like” that), however I haven’t seen anyone else having such a problem. I must say again, it used to work normally before, at same voltages, temps, settings.

Any ideas?

Thanks.

p.s. would you recommend the latest bios 1707?

Yes, go with bios 1707 until we can get our hands on the 19xx and test with 1333mhz fsb.

More than likely you have an issue with not enough voltage to do what you need to do with 400x9, which ultimately is your problem on why you have issues with 400x8. The way the board works is by posting at your original multiplier and the fsb you set in the bios, then after powering up and verifying okay settings, downclocking the multiplier to what you set it as. This being said, if you want to run 400x8, your best bet is to boot 333-366 (an easy overclock in max multiplier), then use a tool inside windows to ratchet up your fsb to whatever you want it; be it 400x8, 420x8, 440x8, whatever.

This is a problem that many of us saw, and is ONE of the few(tRD/tRFC/etc) problems we have with the boards internal functionality.

Holy cow man, that's a :banana::banana::banana::banana:ing amazing setup! So the phase systems are actually full air conditioning setups contained within a case. Brilliant! I will surely look into this a bit more and would love to have this as my project for the hot summer! :D

Your link still doesn't work btw. Here's my link for my score: http://service.futuremark.com/compare?3dm06=934301, so if you can paste your url from the compare page, that would be best.

Appreciate all the incredible info! Even the case by itself without phase is sweet! Did it really have 10 drivebays on the bottom? I want a better physical box for my storage rig that can flow air around the hdds more efficiently, which is kind of hard when you want 10+ hdds in it..

In the OC database, I see L630's and L632's hitting 3.8ghz+ and 4ghz+, granted they may be on water or phase, but their vcore is like 1.6. I am putting more vcore than that and it doesn't even boot into windows let alone be stable.

Can we see a before and after picture of the vdroop pencil mod?

I want to know what exactly im writing on and how much to write.
How many strokes with a simple #2 pencil?
My vdroop is horrible, 1.213v from 1.45v in the BIOS. It is the single reason right now I believe I can't get past 3.5ghz


Also here is a suggestion to worried people with graphite falling elsewhere.
Put double sided sticky tape, I have this brand that is got green and white as its logo colors, its larger in size then the scotch brand 1/8th inch wide stuff. Easier then to deal with say 40 strips of double sided tape. It has the same look as masking tape, and I plan on taping this stuff (not pressing it to every thing in the system possible because I don't want to bend caps, or anything like that.

Tape off the surrounding area so all that is revealed is my resistor that is needed to be modified (yeah small opening eh). And then tape it off around there.


I also suggest to everyone I know to take literally.....a Craftsmen wall-outlet plug-in leaf blower if death and I use it on all my computers about on a monthly basis. It removes all the dust from the case, and power supply. Everything looks day one old again, and fans have a little less stress. It would also blow off some of the graphite that didn't blow off when I would blow the area off (unless I used compressed air which I don't have), anyways you don't want system fans blowing this crap around your case.
I can just see people having graphite that just sits like sand and falls down right on to like your video card. Giving you really awesome video card artifacts or something.
Any graphite not bound to the resistor would be gone. My suggestion...........to keep it clean

[Seb R]

Well...

Got my new p5w installed - problem sorted!

For some reason the mobo just decided that it wouldn't let me run the RAM at 875MHz, and only at 700MHz. Now I'm running at EXACTLY the same settings and setup as before, and no blue screens and no problems!

Probably doesn't say much for asus though...

[WeldZilla]

Hey factory81 where are you getting your voltage droop readings from. I have yet to see a P5W DH with that much droop! If you are reading cpuz then forget it. The most droop I have seen on a MM is .038 . That is a board set to 1.65v in the bios and is running an actual 1.617. My board is running right now with the V-core set to 1.65 in the bios and is running an actual v-core of 1.635. that keeps my fsb purring along at 425 and my cpu running 24/7 at 3825mhz. These boards or at least the couple dozen I have been involved with do not have a significant v droop. I too for now will only run bios 1707. I tried the 18xx and for me they were crap.....
To back up what I say about my system all my score links work!!
Here is one I am happy with!!

Run memory at Auto for dram frequency when overclocking FSB. disable hyperpath and those 2 other memory features under "Enable SPD"

You WANT this enabled..........Your chances of overclocking to a "reasonable" (1ghz overclock seems reasonable on core 2 duo's with air cooling) are a lot harder with SPD disabled and using the limited memory tuning features we have.

So even if your booting @ PC-4300, if your booting at 380-400mhz FSB x 10 (E6700 I think you have), once you got it running stable with your memory "limp". I will call it limp because your memory might be capable of so much more, yet your not even pushing any of it. Then you keep SPD enabled, and try one DRAM frequency at a time, play with the voltages, and watch temps during stress testing.
I got my comp running at 5-5-5-12, 36 TRFC @ 2.2v w/ team xteme pc6400 4-4-4-10 2gb kit, and PC-5700, or 1:1 ratio. I consider this a decent enough overclock.

Sounds like you're talking about an "undervolt" not "vdroop". Droop is the difference in voltage between idle and load, right?

...and i know the guy talking about leaf blowers and double sided tape is kidding, right? a little overkill maybe? I have been know to take the shopvac to my machine once in a while though, but what can't you clean with a shopvac.

[factory81]

I promise you I take a leaf blower to any machine I feel like. I have allergies, and I wear contacts. All that means is as a precaution I take a leaf blower to desktop machines with the case off.

No joke, if your computer can't withstand the air of a leaf blower to clean dust off, then you need to check your wires. Never a negative problem happen......

But no, I seee myself screwing up and doing just what I said, like 2 strokes too many with a standard college kid #2 kids pencil leaves a lil pile, almost like ash sitting on a table waiting to fall off once the board is upright, falling on the video card and screwing it up. Just my luck kind of thing.


Thank you poster above for assuring me CPUZ is not a useful tool. I thought my voltage did drop that much. It does sway quite a bit even if its not in the 1.2's. Is there a better program for the p5w dh?

Thanks, I'll flash the latest bios and try raising the fsb in windows.
