It was easier to sell the entire setup that ran 24/7 folding @ 3200MHz than to sell the E6400 and 5400UL's separately...

And a friend of mine had a P5WDG2 WS Pro he wanted to get rid of (he decided to run a dual opteron rig after he bought the P5WDG2, so it's practically a virgin :D)

The following topic made me want to give that board a try:
http://www.xtremesystems.org/forums/...ghlight=P5WDG2

1st impressions:
bad onboard sound (AD) compared to the P5W DH (Realtek)
refused to boot with more than one stick of OCZ Platinum Alpha VX2 PC8000
vCore rather good, waiting for my Scythe to arrive to test droop
vMCH and vMEM are clearly undervolting, you can correct that with higher settings in bios, but it doesn't do you any good after a bios flash :s
I'll correct it with a pencil mod, waiting for a new Tagan to arrive
Finish of the coolers on the motherboard is much better than the ones on P5W DH, no need to lap them... I simply cleaned them and applied AS5...
Added a 40mm fan to the NB...
Staying @ 333fsb until the new cooler arrives and BSEL-mod for 1333fsb on the cpu is done (will get silver conductive paint tomorrow).

Sorry if this is a bit OT, but I think it's good to know that a P5W DH is a great board.

Interesting. It's good to know that your P5WDG2 hates OCZ Alpha's as much as my P5W DH. Memory voltages are just too low on cold boots it seems. It sounds like you relish getting your hands dirty with all kinds of mods before settling on just *using* your pc :) You really need a mod to run @ 1333fsb? I never had the guts to attempt the pencil mod considering how unstable my board has been.

I am now leaning towards the Intel D975XBX2, and as far away from Asus as I possibly can. I have nothing against their company, but I have small praise for the P5W DH. Mine has been quirky and very unpredictable since the beginning.

The Intel board is a 975X with the ICH7R also, do you think it can read my RAID-0 (on the ICH7R in the Asus now)? What concerns me most is if the Intel board can read either of my EZ-Backup Raid-1 drives :( Has anyone out there moved their drives to another MB?

Regards,
Sker

You don't "need" a cpu-mod to run fsb1333 ;-)
But, since the chipset will be strapped to 1333 instead of 1066, I hope to see an increase of OC.
read more: http://www.xtremesystems.org/forums/...d.php?t=132900
My P5W DH/E6400 were limited to 440MHz fsb.
Hope to see some more with P5WDG2 WS Pro/E6600.

I use badaxes @ work, really nice boards, but I can't get used to the Intel-bios. Yes, they allow you to change almost everything, but when something goes wrong, it's hell to get them back on line...

You have a 99.99% chance that a raid-0 setup migrated to another system is unreadable, so I wouldn't even bother trying.
Datarecovery from a single drive coming from a raid-1 setup is possible most of the time.
Migrating a full raid-1 set to a new board is much more difficult, even with off-board controllers, sometimes things go wrong.

Yeah, I hear you need to move "recovery" jumper when you have a bad OC on the BadAxe's. Small price to pay if the board offers any kind of stability though :) I've never been so frustrated with a MB (re: P5W)!

I figured as much regarding the RAID-0... but I thought... maybe... just *maybe* it would work considering it's the same southbridge. So do you think I could read one of my single raid-1 drives just by configuring it as a normal drive or would I need to make it a member of another array? My ignorance clearly highlights the fact that I've never tried this before :)

If you simply connect/configure one disk as a single drive, you can read the data.
Booting from it would be another question, it should be possible, but I never had the luck...

If you make it member of another array, the data will be erased... (worst case)

I'll give that a try. Good to know I will be able to read from one of them. I am even going to attempt booting from the original RAID-0 (why the heck not?).

So I received my G.Skill HZ's today, tried them in the P5WDH... no go. The board is officially a paper weight. Turns on, but the video fan just runs at full speed, no video, or it shows the ASUS splash screen but locks up (can't even get into BIOS). Now I've got 6 sticks of wonderful memory, and no working MB's... haha. Great. Anyone need spare P5W parts? :D

I did order the Intel BX2, hopefully I'll have it sooner than later! Thanks for all of your help!

sig paste:
Processor: Core 2 Duo E6400 cpu family 6 model f steping 6 rev 44
Motherboard: ASUS P5W DH Deluxe (1901 Bios)
Graphics: ATI X1800 Crossfire Edition
Memory: OCZ 2GB (2 x 1GB) PC2-6400 Dual Channel Platinum Revision 2
Power: Hiper Type M 580 Watts
Sound: OnBoard but it does for my needs

Display: Cibox 19" Widesceen TFT

Well since I'm pretty much at work every waking hour of the day lately, I don't have access to my board, nor do I remember all the settings since the big time I spent tweaking all my settings was around Thanksgiving. However, the least thing you can do is this:

Set your overclocking to manual so you have access to manipulate your settings. On this page you can set your FSB and various voltages. Looks like your memory can run max at 2.2vDIMM, so I'd do that. 1.65 vMCH is good to rule out any instabilities with your northbridge. For your vFSB, set the option that turns the number colour purple, not red.. On CPU, this really depends on the week of production, so unfortunately I can't help you here. Later weeks require less voltage than earlier ones. I'm at 1.60 vCore using watercooling, but for most people this would cause their chips to go up in a poof of smoke. With stock cpufan or decent air I would say you could go to 1.45-1.50, but watch your coretemps!

Memory looks like you have 4-4-4-15, so you can set that. Turn off all the auto options on that page in the first teir of options.

For CPU, turn on microcode update and multiplier modification and leave the rest off.

For fan settings, I disable them all; however some people say they run into problems when they turn off q-fan and related settings. Not sure what to tell you here other than the more you turn off, the less stress you put on your board and the better you're going to be able to overclock.

If you have specific questions about a setting, value, or temperature you receive, let us all know.

Thanks!

Right before you give up the board... Try re-seating the cpu...
Just in case ;)

What fixes 1901 bios update?????

Version 1901 2007/02/09 update



Description P5W DH Deluxe BIOS 1901
Enhance compatibility between EZ-Flash II and USB Flash
Support new CPUs. Please refer to our website at: http://support.asus.com/cpusupport/cpusupport.aspx



File Size 692.36 (KBytes)

I'm running Vista Ultimate on my rig. Verdict is, it's a great upgrade. There are some annoyances with the security windows.

I'm using the 64 bit version and all my system drivers are available. ATI Crossfire included.

I miss iTunes as it does not work with my IPOD anymore under 64 bit. It 'might' work under 32 bit, haven't tried it. On second thought, I do not miss iTunes... sorry piece of software. I'm converting my music files and moving to another service.

Turn off UAC from the user accounts section in the control panel ;)

Sorry guys, can anyone tell me the maximum stable fsb for a 6600?

Noone can, every CPU is different but if you mean on this board, mine loses stabilty after ~430MHzwith 1.65Vmch, stock coler on NB with AS5 applied.

1901 seems to have fixed the super-slow vista installation problems btw

I have a problem with the sleep mode when my CPU is OC'd. Whenever I put my PC in sleep mode I can't restore it unless I completely shut it off and wait a few secs before I power it up again. This usually results in an overclocking failure.

Anyone else has this problem? It's really annoying.

I'm seriously wondering what's going on with ASUS selling a enthusiat board that can not change the multiplier on the Xtreme chip... My board cannot go past 413 FSB stable I wanna have something else :(

Welcome to the club... sigh... Now that I have "upgraded" to BIOS 1901, it turns out that 1901 is even less FSB friendly than 1601 on my setup... BSOD as of 330 compared to 350-370 with 1601... I was about to let of some steam - rather emontional right now - but decided to pass as it probably would have resulted in warning / kick... sigh... But those guys over at ASSUS, I do wonder what the hell they are up to... :slapass:

:D It's very wise that you didn't...

But I have to say to all people who are stuck below 400MHz,
it's plain naïeve to think any bios update or downgrade would solve
your problem.

I fired this board up in august with bios 1201, stable up to 425MHz, beancheable up to 440MHz. I tried all bios versions up to 1707...
And yes, a few megahertz difference, but I think that was more cooling/voltage related than anything else.

So IF your cooling is ok (cpu, northbridge AND southbridge)
AND all voltages (measured with DMM) are ok
AND you still are not able to achieve high fsb,
you can conclude that there's something wrong with
your memory, cpu or motherboard.
Rule out wich of them causes the problem and rma
the damn thing.
A new bios will not solve anything for you :nono:

And yes, quality control of ALL MOTHERBOARD MAKERS (not only ASUS) is rather poor, the way I see it...
(so bashing on ASUS is NOT what this topic is all about)
I have a P5WDG2 WS Pro now, the funny guys at ASUS decided that if you put 1.325V vcore in bios,
you get an actual 1.28V idle and 1.27V loaded (droop is fine, but why the difference?).
If I ask 2.3V vdimm in bios, the board gives me 2.77V (better safe than sorry???).
--> It doesn't look so bad, but the lower voltage really makes it impossible to boot
the rig with two sticks after a biosflash...
They managed to get vMCH right, 1.5V in bios is 1.499V measured on the board.
--> good 'nuff to be rockstable with an E6600 @ 333MHz / 1.27V (Intel stock cooler atm)
One out of three ain't bad I guess :s

Annoying? Like, someone posting the same question abou three times? ;)

Problem with sleep mode is, that the before going into sleep mode,
the current state of the PC is copied into RAM.
As long as you RAM is at stockspeed and spd (voltage and timings), the pc should be able to recover. (unless the nb and cpu power come up too slow)
If the RAM is overclocked in any way, you suffer data loss when the pc goes into hiberantion, so the data to reinitialize the pc is lost, thus you cannot revive the damn thing without a restart.
The reinitialisation requires some bios actions, wich will fail. So after a reboot, that flag is still set and will result in the "overclocking failed" message. You just have to enter the bios, do nothing and boot again...

So no, I don't use sleep mode, I just switch off my screen and external harddrives...

And, btw, this has NOTHING to do with P5W DH problems...

NEW PSU DIDN'T SOLVE MY ISSUES!

I origionally thought my random reboots and lockups were caused by a faulty psu, this is not the case. I am fairly certain its the bios.

Can anyone please shed some light on this for me? Has anyone had the same lockup/reboot issue as I have with the new 1901 bios?

from all that ive read.....the 1901 bios is crap.....id say reflash back to at least 1701 or before....

I would not recommend advising people to turn off UAC without a disclaimer.

Its a security feature that will help stop any trojans that get on your system trying to run with an elevated user permission.

With UAC turned off, and IF you get some nasties on your system that try to run under administrator mode, they will run, With UAC ON this will not happen.

Just be careful and be aware of the impact if you turn UAC off.

stick with 1707 been running fine for me,

Why does my computer start up in the middle of the night at random times?

I shut it down and come back later and its on. Never at any specific time. Cant figure out why. Help.

screw it i made an entire thread about my issue to get more viewers...

try running everything at stock or use 1707 bios

I would try running 1707 bios if the system didn't lockup during bios flash. I'm thinking of ordering a chip from "biosman" but the order process is a little confusing.

Has anyone tried getting a bios chip from biosman?

Heres the real question; I've heard of "hot flashing" where you take out the bios chip while the computer is on, so is it safe to assume that once the computer gets past post and starts to load windows that it is no longer a major effect on the system? I mean, once it gets to windows boot screen, could the bios chip STILL cause a lockup/reboot?

I had lockup problems when my data drive was going bad last August or so. Once it was replaced, no more lockups. THere was a subtle click sound, usually followed by a useless computer that had to be powered off...

lost most control of my fingers so pleaqe bear with me, it hurts like hell 2 type. and take tons of meds so im very forgetful too
awhile back there was discussion on what driver 2 use to with the sil device but the search doesnt seem 2 be limited to this ongoing msg. heres whati got
2 raptors on ichr7 for quicker bootin and 2 500gig wd drives on sil as raid0 but they r a hell of a lot slower then when i had em on te intel ichr7 forgive me if i spelled t wrong.
tried putting all4 drives on the ichr7 as 2 arrys but that volume external volume thing screwes it up.
any suggestions or the msg nos they have that discussion. more i type the worse the pain till i have 2 resort 2 taking the morphne and valium then i cant do squat tech wise. i hate that cause im a cmptr nut/freakwhat ever u wanna call it

thank u

after disconnecting both hard drives in order to do a boot from CD with norton, the same issues appear.

Kev,

Two things,
1: you are experiencing electrical power fluctuations that are triggering the BIOS to think power has been restored... a long shot.

2. you have the Wake on Lan setting on and something on your network is triggering that.

Having said that, i have no idea your situation so the above is a guess. Check your bios settings regarding wake on power and wakeon lan.

I have a similar problem, no fix yet. Your problem might have s.t. to do with the use of USB ports 3 and 4. Those ports will wake up your pc if you use them. Perhaps the story below will be of assistance to you.

After I shut down my pc it always immediately restarts again. I checked the keyboard, mouse and USB cord on another pc and it worked fine there, no unwanted restarts.
My latest BIOS update is 1602, but the problem was there before that update as well.
All the setting in the BIOS (WOL etc.) are correct.

My computer has 4 USB ports at the back and 2 at the front. (the 2 extra optional ones are not installed).
The 4 ports in the back are situated like this:
||
||
I do not use the 2 ports on the bottom of the above picture as they are dedicated to remote wake up which I do not use.
The 2 top ports of the above picture I use for the DiNovo keyboard and mouse. These are the 2 problem ports that would make my computer start up again after full shut down.

I wanted to be able to shut down my pc without having to use the power button so I installed a pci USB card with 4 ports. I used that to bypass the 2 problem USB ports and it worked, no more unwanted restarts.
Out of curiousity I tried the top 2 problem USB ports at the back of the computer again. To my surprise they gave no more problems when I shutdown the computer, no more unwanted restarts.
Just to see what would happen I took out the installed pci USB card with 4 ports.
The top 2 problem ports still gave no more problems so I left the pci USB card out. (after all, not too many pci slots on this mobo).

Next I found out that when I use the 2 USB ports at the front of my computer now cause the computer to start up again after I shut down. I have to take out any USB device in the front ports before I shut down the computer.

I am still in contact with the ASUS support team, I will post any positive development re this issue. I would also appreciate to hear from forum members if and how they solved this problem. (apart from never shut down pc again ;)

Someone at ASUS screwed it up. FTP-server is up, but that's all, up to now:
ftp://ftp.asus.com.tw/

I'm having a problem with my computer. I have an asus p5w dh, intel core 2 duo, 120GB sata and 320 GB sata, samsung lightscribe dvdr, and a usb card reader installed in a P180 case. The transfer rate on my computer is slow. My 4 year old laptop is faster. When I download apps like itunes or any other apps the transfer rate is 30kb's or less. I have a studio and to copy my sound library it took forever. Like a few days. Everything downloads very slow. I did a comparison opening some winrar file from my laptop and it opens them in seconds. With this computer it's taking me minutes, anywhere from 8 to 212 mins to open depending on the size. Please tell me I have something setup wrong. Help would be so greatly appreciated.

Sounds like your drives are operating in PIO Mode.
Check your cables, and the transfer mode settings within Windows ( Device Manager => IDE/ATAPI Controllers ) => xxxx Channel => Advanced Settings.
Make sure they're set to DMA Mode.

for cd-rom & hdd;)

Hey man, too much info!

Easy fix I posted a couple times already. Just remove the ez-raid jumper and use the right orange sata connector. You'll have 4 drives directly on the ICH7 southbridge and will be able to manipulate them with the intel raid config during post.

Best of luck.

Well, not sure if it was related to the 1901, moving up to 4:5, or what, but my two sticks of corsair pc2-8500c5 sticks are officially dead. This is my second set of these dimms, first of which got replaced by corsair a month and a half ago or so.

When we got the 1901, I wasn't able to manage my original 385x9 1:1 and had to move down to 380x9. After some benchmarking, I determined that 4:5 gave me more performance, and the box ran great for a week and a half up til this past weekend. After experiencing tons of random reboots and misc box crashes, Sunday night my computer went into a serious reboot cycle in the middle of the night, and the ram degraded to a state where it won't even boot windows now.

Popped in memtest86 and I get thousands of errors every second. Nice, a?

I'm frustrated and upset over the incompatibility with 1066mhz memory and the intel 975 chipset, so I'm about to order some 800mhz stuff. I'm not sure whether I'll go g.skill or another company, but I'm done dealing with these problems.

When I RMA these corsair dimms and get a new set back like I did the last time, they're going up for sale.

Thanks, I'm going to check on that right now.

Just ordered: G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Retail

part number: F2-6400PHU2-2GBHZ

http://www.newegg.com/Product/Produc...82E16820231065

I'll be curious to see if I will be able to get over my ~3470mhz wall with this new mem..

I checked and that wasn't it. It was already set in DMA mode. Any other suggestions? I notice that my my RAM runs at the 533 instead of the 800 so should I tweak something in the BIOS?

Hi Guys

With BIOS 1506 boot at 385 FSB max
With 1707 at 370 and
With 1901 at 365 not stable

With the same setting:
Vcore = 1.6125
Vmem = 2.4
FSB = 1.5
MCH = 1.85
ICH = 1.20

PCI-e frequency = 115
Performance mode = Turbo

The PC is a E6700 W/C (eheim 1250-triple radiator with 3 12cm fans Cuper bloc by Eleven)
Memory : Super Talent DDR2-800(2X1GB T800UX2GC4 CL 4-4-3-8
P5W-DH Dlx rev 1.0
Enermax Noise Taker 600W
3 SATA (2 WD raptor 74GB RAID 0 on Intel) and one Maxtor Maxline III NCQ 300GB

The highest fsb that I can go is 420 ONLY from Windows with SetFSB tool
From BIOS 1909 3650 not stable
Whyyyyyyyyyyy???? 



PS. - 1 hour memtest Nr 5 at 900MHz memory with no errors (from boot CD)
-Temp idle
in Speedfan 30 C
with Core Temp Beta 0.94 50 C ?????
The correct tmp is?????????

-what are the settings for :
Peg Buffer Length
Link Latency
PEG Root Control
PEG Link Mode
Slot Power

Any suggestions????? Regarding mainly FSB

I already replace the thermal compount with AS5 and lapping heat sinks

This is a download of Itunes. I have a wireless desktop, but I'm using a wired connection. My old laptop would download this so quick. I am missing something. Can someone give me a site to run some performance tests please.

Hi,
Note: lawrywild's current recommended BIOS version: 1901

When we got the 1901, I wasn't able to manage my original 385x9 1:1 and had to move down to 380x9. After some benchmarking, I determined that 4:5 gave me more performance, and the box ran great for a week and a half up til this past weekend. After experiencing tons of random reboots and misc box crashes, Sunday night my computer went into a serious reboot cycle in the middle of the night, and the ram degraded to a state where it won't even boot windows now.

Popped in memtest86 and I get thousands of errors every second. Nice, a?

I'm frustrated and upset over the incompatibility with 1066mhz memory and the intel 975 chipset, so I'm about to order some 800mhz stuff. I'm not sure whether I'll go g.skill or another company, but I'm done dealing with these problems.

When I RMA these corsair dimms and get a new set back like I did the last time, they're going up for sale.

Have you tried memtest in other divider??, I mean 1:1... I was indeed surprised when you said that 4:5 was working. I´ve a pair of D9 rated at 1000 and the only way they work passed the 350 fsb barrier its 1:1.
Its a trc/trfd thing.

Where did you learn about overclock? Try to low all of your voltages.

I got 2 x 320 Segate 7200.10 in RAID 0 and i'm only getting 60MB/s Read. I'm on the Intel ICHR7 controller. Bios is 1901. What could be going wrong ?

Have U a good guide for this mobo???

I think 6600 is beter CPU for OC than 6700

Scoop,
I have no idea why it's that slow on your side. I got the same drives here and they work fine with a decent speed.

What is officially the most stable bios for this motherboard? If I'm running an e6600 and some ddr2-800 and plan on sticking with vista, what bios will give me stability and performance?

Those voltages are definately high. Are you getting a bad vdroop? I had to really volt my cpu to get it stable before I did a vdroop pencil mod. Now I'm stable at 3.55 with 1.55v in bios. I lowered my clock to 340 for now because I moved the case and temps aren't that great (60ish load).

One suggestion is to drop the turbo.

Vdroop of less than 100mV is not a problem.
You have only 41mV, according to Speedfan, measure again with a DMM and you will notice it's even less.

If you take away the droop (vdroop mod agressively tuned) you'll get a heavy increase of PWM-noise and worse overclocking results.
You'll notice that top-OC-people take care of the filter caps to avoid that...
So a vdroop mod might help, but don't push it, leave a little droop as it's part of the regulation circuit.

The voltage regulator of the P5W DH is limited to 1.60V (specs :fact:), better to lift that up with a vcore mod and leave the droop alone.
But if you're on air, 1.60 is already over the safe side for 24/7 use, imho...

And, btw, what you call a permanent disease is actually on Doctor Intel's prescription (check the datasheet of your cpu);-)
Those doctors invented the term "droop"...

The thread is pretty interesting, but it shows already what I know.. Getting over 1000mhz fsb is really difficult. OP in that thread used 2:3 with lower base fsb to do higher clocks in mem, then later went up to 1066mhz mem..

Super Pi @9x355fsb = 3200Mhz 2:3 533mhz 4-4-4-12 at 2.4v
32M Single = 15min 20.453s
32M Dual = 16min 36.657s / 16min 33.500s

So looks like for Super Pi v1.50 32M at least I've managed to get 2x1GB Gskill PC6400PHU2 2GBHZ Micron D9GMH to 533mhz 4-4-4-12 at 2.4v.

What's strange is that I got home from work last night, changed dual dimm positions (was in the two orange slots and moved to the two black slots), and it worked. I have no problems in 4:5 and 1:1 now.

When I did my memtest'ing yesterday, it was in every memory mode that I had problems; 1:1, 4:5, standard, and overclocked. Like literally memtest86 was spitting out errors thousands by the second.

I'm going to try and debug this later today to see if it is in fact memory, or maybe the dimmslots on the board. Whatever it may be, I'm happy I ordered the other memory and hope that I'll be able to sell this corsair stuff. :)

Another problem I'm having is that most of the times when I reboot it results in an overclocking failure. Is this normal?

Nopez, that's not normal...

Maybe you left something in bios on auto
or one of the voltages you chose (vcore, vmch, vmem, vich)
is a little too low...

Perhaps a lowly E6300 is 'special' (or maybe Week 25 is great), but I'm using AUTO on vCore and have no issues whatsoever @2.87Ghz. Other values like vMCH are higher, though. "Trial and error" is the only real way to find out what works, but not changing something after every failure seems bad...

400mhz x 8 = 3200Mhz
1:1 mem

vcore 1.35v
Vmch 1.55v
Vich 1.05v
Vdimm 1.9v
FSB termination: Auto

Should I change Vich and/or FSB ter. settings? I haven't messed with those much because I'm not sure what they do.

I have Vich on 1.20 and vFSB on 1.40 myself. Working perfectly on a 9x356 (3.2ghz) OC. :)

Try this:
Vmch-1.6/1.65 depends of your motherboard revision
and if is still unstable try raising fsb termination- 1.4/1.5

That should work

imho, most settings are fine...

maybe vcore is a tad low, 1.375V could be enough
and give the OCZ's 2.2V, that's what they ask for
FSB termination voltage of 1.20V is enough, never needed more, not even @ 440MHz (but it depends on you cpu, so higher could be better, not with my E6400)
vmch and vich are perfect in my opinion (no need to overheat those chips)
higher is not always better for stability

What revision is your P5w ? Mine was working all the way up to 400 with 4:5 divider ( ddr1000) with VMCH=1.85. I've already tried it with G.Skill 8000 ZX ( D9GKX ) and Mushkin Redline ( D9GMH ) and both passed dual instances of S-Pi 32M. But whether it's Orthos stable or not, that I don't really know.
I'm runnin' my E6600 @ 420 and my board won't even post at all other than 1:1.
But I agree with you that the lack of trc/trfd control really hindering this board for memory performance.

i've never seen this one.
i was wondering why my gigabit network slowed down, looked at the local area connect icons (i havethe 2nd nic turned off) but the icon on the first nic shows what seems like a share hand at the bottom left. it had the network running at 100mbps insted of 1 gig.. looked back at status i was back at 1 ghz. i have never seen this before and dont even know what 2 put in to search forthis wierd thing. anyone seen this before and if so what the hell is it & how do i turn it off?

thank u

timings shown in screencap. I just did a quick S_pi test as I'm about heading out to work.

I responded to your post because you said you had problem reaching > 350 fsb in 4:5 even with pc8000 D9s, that really puzzles me. Perhaps it's related to the memory internal timing optimization, but it's just a wild guess to get off my chest.
My other G.Skill pair with "supposingly better" D9GKX chips needs higher voltage (2.4v) and more relaxed timing 5-5-5-15 to reach ddr1000 in 4:5.

@clee :

you think is possible for me to obtain the same result with my ram and mobo?

mine is rev 1.02... (1.65 v).. or norbridge low voltage is a limit?

Ps.: my ram are D9 surely stable @ 925 mhz 4 4 4 8 2.2v.. ( more I havent try..)

I tried yesterday but nope...:( ( 2,4 v 4 4 4 10 & 5 5 5 15.. )

Tanks

My guess is that's i't's the rather high Vmch that allows you to run 4:5 at 400 FSB.

It's simply not possible on my board either, no boot with 400FSB/DDR 1000 set in bios, not even with 1.65Vmch and 2.35Vdimm 4-4-4.

WITH BIOS 1901 :toast:

I am having problems trying to install Raid0 using Intel Matrix Storage Manager.

These are the following steps i done.
1. Enable Raid in bios
2. Ctrl+I to create a new raid
3. F6 durning the begining of installing window xp
4. For some reason it was unable to find my USB floppy disk
5. If i try to skip installing the Intel Matrix Storage Manager (F6) during the window xp setup, there will be blue screen.

Inputs please.

and I guess you're right.
I've tried Pencil Mod on V-mch But i don't have tried 4:5 i only searched the max stable fsb 438 in sig whit a real voltage of 1,6 v. ( whitout vmod drop's up to 0,1...)
Now i've burned my mobo misuring whit multimeter :( ...
Warranty bring to me a new mobo, but the revision is te same of the first :eek: :rolleyes:

Kadinho,

Could you tell us your voltages and settings in bios please?

Is it bios 1901 that allows this only?

you will ask about the high vfsb, I´ve tested with lower voltages and I got errors in orthos right after I start it, the only way to solve them was giving more juice to the vmch (1.55 -1.65).
but I choose to running this way (high vfsb & default vmch)

Has anyone else got an issue booting from USB drives with bios 1901, i have five USB pen drives and when i updated to bios 1901 i could no longer boot from any of my USB pen drives, all i get is a message on the screen saying "Missing Operating System", if i go back to any bios previous to 1901 i can then boot from USB.

Also with 1901 i can't use the "ASUS Crash Free" feature (Alt + F2) to recover the bios, it doesn't detect any CD ROM it just goes in to a loop saying that it's looking for CD/Floppy or USB, when i use a USB pen drive it finds the bios file (P5WDH.ROM) and says it's reading the file, but then it just sits there doing nothing.

Has anyone else had any of these issues with bios 1901 or am i the only one?

Thanks!

So, even with the newer BIOS, no one has managed to use all the SATA ports as stand-alone units?

Connecting drives to the orange ports for me results in the system locking up within 10 seconds of POST completing......and i am not seeing any JBOD options anywhere....

Any help would be appreciated :)

There is no such thing as a stupid question, in my opinion, and I still regard myself a NOOB in every aspect and situation available. I have disabled Hyperpath and followed every advice in this thread (and similar threads) and experimented with new settings. But in my experience, the later BIOS's are less FSB friendly all settings equal. That's just the way things are over here too...

Yeah, you do need high Vmch, but you did the volt mod already right ?
Anyway, you are runnin' your e6400 @ 438FSB , why bother with 400FSB and 4:5 ?? If you meant to run the memory @ ddr 1100 on 438FSB, that's gonna be tough. I'd be balling my eyes out if you could do that. If my memory serves me well, the best I could do was ddr1030 (412FSB ) even with top rated D9 sticks.

He's using a 2:3 divider on 350FSB to hit ddr1000+. I don't think it needs much VMCH for that.
It starts getting tricky when approaching 400FSB.
My own observation shows vmch=1.65 is adequate for up to about 380 ( i.e. ddr950 ), 1.75 pushes just a bit more, but still not enough for ddr1000.
Actually I was under the impression that vmch=1.85 plus pc8000 D9 memory would warrant DDR1000+ at 400FSB+, but judging from monza's post, I guess I was wrong.

Hey!! Whait a minute ther is a Mistake:
Sorry for my poor english :( i'm saing that mine ( my ) was a stupid question... because everyone know that "Yperpath3" need to be disabled.. you got it? :)

aniway if you are using a QX ( Quad core ) the Fsb you are hitting with tis mobo is good, if you want higer fsb P5b deluxe or commando ( all the intel 965 ) are the choice:)
Or you can try whit vmch mod.

thanks for response:)

I've hitting the 438 FSB @ 1:1 whit my death mobo ( vmch pencil mod ) but I don't have tried 4:5 @ 400 mhz fsb whit Her...

Now the new one isn't modded and is stable @ 420mhz 1:1...and I've advised that 400 fsb 4:5 ram isn't possible..
obviously vmod coming soon;)

Aniway mine was just curiosity, because a Xeon 3060 is cooming soon :)

9x390 mem 1:1 is max for me. The board rev is 1.02 and NB is watercooled. Tried 9x395, but prime rebooted after two hours. Increasing vcore didn't help. Now I'm trying to stabilize mem 4:5. This is with bios 1707.

Settings:

vcore 1.475
vmem 2.2
vfsb 1.4
vmch 1.65 (board's max)

It starts getting tricky when approaching 400FSB.
My own observation shows vmch=1.65 is adequate for up to about 380 ( i.e. ddr950 ), 1.75 pushes just a bit more, but still not enough for ddr1000.
Actually I was under the impression that vmch=1.85 plus pc8000 D9 memory would warrant DDR1000+ at 400FSB+, but judging from monza's post, I guess I was wrong.

Running async seems to put more strain on the NB hence the Vmch question.
I can run up to 9x 430 1:1 100% stable but 9x400 with 4:5 divider won't even boot.
I have a gut feeling that higher Vmch will help.

For 400 FSB i'm using 1.55Vmch, that's fully stable.

This board keeps puzzling me.

Hey all,

I got my new g.skill pc2-6400c4's and ran a bunch of superpi tests last night with both 1:1 and 4:5 using both the g.skill 6400's and the corsair pc2-8500c5's (at 4-4-4-12) with the maximum fsb's I could handle.

I'll include screenshots of some cpu-z's and my superpi scores, but I was surprised that there was really only tenth of seconds differences between them at similar clocks. Unfortunately I wasn't able to reach any higher stable clocks than ~384fsb in both 1:1 and 4:5 (~975mhz mem) at 4-4-4-12 6-28. So I guess since I've ruled out memory and northbridge (since I got the thermaltake extreme spirit 2), it must be my pos cpu. :)

What surprises me though is that I get better overall performance at 4:5 at a slightly lower clock than I would at 1:1. I thought that 1:1 was supposed to be the best? Either way, I'm content now.

I honestly don't know what happened to my corsair pc2-8500c5's to cause them to flip out on Monday because they're working perfectly now in either set of dimm slots on the motherboard. I gave it 20 minutes in memtest86 with no errors, where the one time last week it would scroll thousands of errors per second.

Anyone want to buy a month old set of corsair pc2-8500c5's from me, only slightly used, and in perfect working order? I can take pics of successful memtest and show my highest clocks in both 1:1 and 4:5. :) Please send PM.

I'll post pics and stats and stuff in another thread outside this one since these dimms are a bit finicky with this board and would work much better in an nvidia 680 or rd600 board.

you´re right

But it depends of other factors as well

Anyone have any other ideas on why my dl speed is slowwwww? Should I RMA the board? Should I get a different brand? please help

hello all,

ok, i ve not been on that topic for a while, ad i got a couple of questions :

- is it better to use 1:1 synchro FSB/DRAM or not ?
- what is the behavior of the P5WDH when using 4 sticks of ram ?

Before i was using 2x1Gb of Gksill PK with the following config. :
fsb 402 / Vdram 2.0v / 1.65 / 1.20 / 1.30 / RAM at 1:1 4-4-4-12

I just added one more Gb (2x512Mb) of the same PK serie.
System will post, but i get memory errors. When using RAM at lower speed (301Mhz) but still with FSb at 402Mhz, i still got errors.

I tried the sticks individually, all is ok.
I tried a fsb of 375Mhz with a ratio of 1:1, all seems to be ok.
Mobo won't get high fsb with synchro RAMs ?

4gb requires more chipset voltage(MCH) than 2gb, and hence your errors.
