Hi guys, can anyone help me please? :confused:
I've just swapped out my E6600 for a Q9450 and updated my BIOS to 2801. I'm trying to install Vista but I keep getting 'memory management' BSOD and sometimes it just restarts after a BSOD (too quickly to read the exact errors).
I've ran the Memory Diagnostics tools and it says my memory is fine. I even replaced the RAM with another pair but still it crashes. I was reading this thread and someone suggested trying to increase the voltage on the RAM so I increased it to 2.0v but still no joy :( .
Is there a way of knowing whether it's the CPU or the BIOS that's causing the problem?
So far I know it's not the GPU, RAM or HD.
I'm using:
P5W DH Deluxe (2801)
Q9450
2GB OCZ
320GB HD
7800GTX
Thanks in advance guys! :)
Did you reset all the BIOS settings to AUTO before trying things? The old settings that worked OK with the E6600 might need tweaking...Quote:

Not having a lot of luck on the support front. Each time I contact a new support technician (up to #3 now), I hear encoraging talk of how the 1.02G issue will be looked into, then nothing. If I had to guess, the eager support people go ask about 1.02G then they are told it would be expensive to admit the problems and to ignore any questions.
I'll wait another week on the current guy, then seek another way to get ASUS to at least tell us that the 1.02G version is no longer supported and to please go buy another ASUS board...
I have a q9550 along with an asus p5w dh of course. Everything is fine except it always stays at 2.83ghz even when at idle. My old q6700 would adjust depending on system demand. I have set Current power plan to balanced and auto settings on all in the bios. Anything else I need to do or any suggestions??
Thanks
Oh, running vista 64, sp1
Are these 3 techs at the same level or have you tried a supervisor? I don't envy you going through this hassle but I sure hope your persistence pays off.Quote:

So in many cases it makes P5W to be a leader even with lowered Crossfire bandwith on it, then 8x PCI-E slot is 4 times slower than 16x PCI-E 2.0 on X48.
Hi,
I try to update my bios on my P5WDH and it fails
2004 to a more recent version (i tried with all versions and last 2801)
Because i want to update my CPU.
I try by 3 methods
Alt - F2 and a usb key with P5WDH.rom
result : Failed to flash
form bios with Ez utility 2:
result : bios data does not match the file content
from cd-rom .iso (afudos)
result : block data does not match file 0x000F0000
Can you help me ?
Best regards
Allan
N.B sorry , i am not sure that it is the good place for this question, but i wish that a expert can reply :)
Oh somebody please reply! I am trying to same thing, going form 2206 to 2801 and have failed both Alt - F2 and EZ Utility 2 methods with a USB Flash drive!
I just updated the BIOS today to 2801 from a USB flash drive by using the EZ flash utility. I'm not sure which BIOS was present - perhaps 2704? However, the BIOS upgrade did not solve my problem. :(
I am using an E7200 on the P5W DH 1.04G. Unfortunately there is no way to change the core voltage with this CPU to anything but "AUTO." Default core voltage is 1.05V so OC > 3GHz is impossible. The same CPU runs fine in other boards at 3.6-3.8 GHz. The CPU I previoulsy used in the P5W is an original E6700 from 2006. That CPU works fine and it is possible to change the core voltage. Is it just impossible to change the voltage because the E7200 is too new a CPU for the P5W DH? Thanks.
EB-1, this is a frequent issue with our board. You should flash using this procedure:and then remove both battery and jumper to have full CMOS clear. I think this should help you.Quote:
EITHER Flash using AFUDOS and the tags "afudos /i****.rom /p /b /n /c" (without quotes) , then clear cmos as the manual describes [Credit - OPB] OR Disable Speedstep and Enhanced C1 Control in the Cpu Configuration section of the BIOS. [Credit - DjLeco]
Well, I'd say reboot the PC a few times, since EVENTUALLY you get non-AUTO settings on any CPU. Your 45nm E7200 would be an issue on a 1.02G board, but your 1.04G should be OK...Quote:

After re-booting the system posted 4ghz as if it was taking the new lower voltage. I went into the bios and notice the voltage value was 1.4 (not the value I set) but it was highlighted differently. My system was not stable but I have yet to do any further tweaking.
I would think the bios should at least report the values set by their overclocking utility. Is the utility a backdoor to setting up the bios on these older rev boards? Is it advisable to continue down this road?
First off, a 45nm CPU in a 1.02G board is stuck for now with AUTO or nothing. Even then, I have to cut back the FSB from 333 to 290 so my Q9450 doesn't crash within minutes of booting.Quote:

You could call 812-282-2787 and ask for help, but so far I've gotten eager techs who take my info and never get back to me. Not even to tell me they are making no progress...Quote:

http://www.benchzone.com/datas/users...oop-pencil.jpg
Better to set 1.4V than hardware mod. Such voltage isn't high for 45nm. Many work at 1.5V+.
Yes, 1,4V is still safe votage for 45nm CPUs but many people are afraid of setting this voltage because they think it's too high. I just don't know why.
One reason: no $300 here to throw at another Q9450 if mine turns out to be touchy about high voltage...Quote:

One 45nm E8400 was used at 1.8V 24/7 and after a month its overclocking down from 4.3 to 4.1GHz. Later it was set to 1.6V and works about a year without problems.
1.8V is very high, but 1.55V is nominal for some 45nms in retail high end computers with factory overclock.
The funny thing is that even though I have a revision 1.04G board,
I do not get anything other than VCore set to auto in the 2801 Bios.
I have a E0-Stepping E8400 that only gets a Core Voltage of 1.168 volts,
which I find too low. According to Core Temp, my processor has a VID
of 1.2125 volts, which the board doesn't even set :confused:
So far, no matter how often I performed a CMOS clear, took out the
battery etc., I do not get the manual VCore option :confused::confused:
I recently got a Quadcore QX9650 C0 step. I reinstalled Vista 64 after swapping it with a core 2 duo.
now the problem is that with only 2 cores enabled, Super PI completed 32M without errors. When I enable all 4 cores Super PI fails.
I am sure that my RAM does not have any issues. I am using the latest 2801 BIOS.
Btw, in windows XP without OS reinstall, I am getting BSODs randomly.
Any help?
Found the issue! It was to do with FSB speed. Reducing it by 10 worked.Quote:

What FSB were you running?
I found the QX's to clock the best if you leave the FSB close to 333 and tweak the multiplier with a little FSB changing. 380x10 (1.65 mch) was not prime stable even for 15 minutes of the small fft test even at 1.4v, though its worth noting that higher vcore did help stability slightly as i started with 1.3625v, while 333x12 passed a full pass of small fft prime (8k-64k-about 3.25 hours) with 1.3725v (1.368v shown in cpu-z), with the vdroop pencil mod. (200 mhz higher at lower vcore, take note of that).
to compare, 400x10 was a complete no POST at 1.4v. Oddly enough with both a 1.02G P5W (using a X6800 dual) and the 1.04G with qx9650, I couldn't reach 400 fsb, but I didn't try 1.75v mch. The 1.02G wouldnt even do 370x10 on the X6800 unless i pushed the vcore to 1.65v (!). But 340x11 posted at 1.55v.
Someone mentioned a long long time ago that they 'felt' that the board, when set to 370x10, was actually initially posting (before bios init finished) at the default multiplier (11), which meant the cpu was momentarily at 370x11 (4.05 ghz) then setting it to at the end of the BIOS init, which explained why 370x10 posted at 1.65v but not at 1.55v, while 340x11 posted at 1.55v. Possibly the CPU has to power up and accept signals at the FSB and its stock multiplier, before it can be told to lower it by the BIOS signal (?)
I never bothered to test something like this, but it would have been easy enough to set it to 370x11 to see if it still needed 1.65v for POST. I no longer have the x6800 or the 1.02 board though....
Does that Bios support E stepping CPU's?Quote:

An alternative for a TRUE pure cmos clear, is a FLOPPY/Flash drive award based bios flash, without using crashfree tool to do it.
I know when you first do a bios flash, you have to select some settings and "save and exit", then when you go back in, all the voltages are unlocked. If you've done this in the past, you would know if that's simply not working anymore or not....
I was running FSB at 333 with Auto volatage for MCH. Also my Vcore starts only at 1.5VQuote:

First of all, you're lucky because you've got a CPU with unlocked multiplier. You should try to make 333MHz stable. I think increasing FSB Termination Voltage to 1,3V and MCH Voltage to 1,65V should help you. After that you can overclock your CPU with multiplier. By the way, in your motherboard voltage really starts at 1,5V? I heard that in older revisions voltage starts on 1,4V but not on 1,5V.
I've had several cpus in my 1.02g board (e6700, e6750, e2180, e2220) and could never obtain a high fsb. 300-310 is about the most I can get stable...believe me I've exhausted all possible cpu/chipset/jumperfree setting combinations to no avail.
Now I have an e8500, and its the same thing. It will only post at its nominal speed (3.16ghz with 333fsb) if I leave the 'AI Overclocking' option to auto, which is undesirable as I like to manually set everything like voltages and ram speed etc.
If I set 'AI Overclocking' to manual, put the fsb to 333 and leave all other jumperfree options still on auto, it refuses to post. So how the hell is the auto setting making 333 fsb stable? Anyone experienced a similar issue?
Also, once I change 'AI Overclocking' from auto to manual, I have to use the 'load default settings' option in bios to post again - simply changing the option back to auto doesn't work.
Same here. With my mobo, all I can do right now is 320 Max. Beyond that if I disable 2 cores, I am able to go past 333. What a trade off :)Quote:

Having a unlocked multiplier is one thing, but getting the CPU with that totally free is... :)
Just an update. Switching ram to higher speed Crucial and thus being able to use a higher fsb:dram ratio (4:5) has allowed me to set almost everything manually.
If I disable speedstep and thermal control, the cpu only runs at 300-400mhz, but I can still adjust vcore with it on :confused:
Now I can do 368 fsb by raising FSB Termination and MCH voltages up a notch. anything further and memtest freezes about 10mins in. Enabling SPD solves this, but its setting weird timings of 5-2-2-18 and its only good for another 10mhz so not much point.
Another finding..
Initially I had Vcore in BIOS starting from 1.5 . I then used AI booster to set a voltage below 1.5v. After this, BIOS showed voltages starting from 1.2 volts.
Well, AI Booster displays 1.19V but the vCore setting I picked of 1.375V is still there.
I'll wait for the crash before abandoning it...
Well people.
My old E8500 run stable at 370FSB with 1.8v in memories and all voltages in AUTO. I can get 3.5ghz.
Now, i change the cpu to a E8600, get 400FSB (3.8ghz).
I have to get more test. I guess that when i select 1.40v in vcore cpu can get 100% stability.
Tomorrow i run some more exaust tests.
Oddly, it didn't crash, but even though Orthos ran for 3+ hours OK I experienced some corrupted RAR file downloads that only became uncorrupted when I downloaded them again after going back to my original settings. One corrupted file occasionally I can understand, but not three that didn't happen again.Quote:

Just wondering something:
Anyone know if the C1 stepping of QX9650 is supported (like the C0 steppping is?) Or the QX9770...
Corrupted rar files are in my experience symptoms of the on-board network not liking the overclock. Here I can overclock my q6600 to fsb 350 but lage rar files over the local network are unusable. Around 340 things are much better. I tried everything I could think of raising all kind of voltages, but never found anything that improved matters.Quote:

But I need to set memory voltage to 2.4V for this setting to work. That's why I'm asking if there's any way to lower this voltage and keep the board stable? Thanks in advance.
Hi!
I get a 404 page not found error message when I try to load up the F.A.Q at asus.com. Perhaps you peeps can help me instead?
Does this board support booting from USB? I have a USB pen-drive but I can't get the computer to boot from it. The latest BIOS is installed (2801)!
Thank you for your help.
Try changing the usb emulation options to floppy, hdd etc.
Hi all,
I have just installed a G.Skill dual channel kit on my p5w dh deluxe. Every module is 2GB, so the kit offers a total capacity of 4GB.
But there are some troubles:
- with only a module, all works fine: with vdimm and timings default (2.1V and 5-5-5-15) no problem; windows vista 32bit boots normally;
- with the two modules (in dual channel, into black slots) windows try to boot but after a few moments a very fast BSOD screen appears during boot. Also increasing the vdimm to 2.2V the problem doesn't disappear.
I have also tried to enable the memory remap feature: so the motherboard recognizes 4GB (instead of 3,2) at boot but with this setting BSOD with Vista. Also disabling the memory remap feature, there is the same problem: with two modules vista doesn't perform the boot but a bsod appears.
How can I solve the problem?
Thanks in advance!!
What is FSB : DRAM? What FSB ? Are u overclocking?Quote:

Check your RAM with Vista's Memtest utility at bootup.
By anychance if u have WinXP, is that working OK?
PaVi90, you need to tell me what is your current BIOS setting. I bet that you need to increase your MCH voltage.

Thanks a lot for your replies!!
Okay, so you need to use those settings:Quote:

I think that with those settings you should be stable for sure. Don't forget to set right timings (5-5-5-15-5) too. It would be also good to know what is your CPU.
Ehm... I need 1066MHz: now I have installed a 800MHz kit, so it's ok. But today I have had a new ddr2 kit, running at stock speed of 1066mhz, so I want to try to run this kit at its native speed.Quote:

OK, I'm giving 1.45V a test. Anyone know why CPU-Z shows an even LOWER voltage than the AUTO setting was giving?...
http://www.mikepaul.com/CPUZ145.jpg
Mikepaul, CPU-Z shows you real voltage, so in your case AUTO setting is giving you about 1 V under load. This CPU can't be stable.Quote:

Best bet is to use something slightly less that 1000Mhz in 1066 strap and use CL4 latency on your RAM.
Also VMCH needs to be at 1.65 in my case.
ok; vMHC to 1.65V. Do you suggest any other voltage setting (FSB, ICH,...)?
Thanks in advance ;)
VFSB must not go beyond 1.3 for 45nm as it may destroy the CPU.Quote:

Nothing done: I have tried everything but without success :shakes:
PaVi90, you want to set FSB Frequency to 320MHz and DRAM Frequency to 1066MHz. It's impossible because you have to use 3:5 ram ratio for that. And this ram ratio forces 800MHz strap. This is the reason why your board is unstable at that setting.
ok, but if I want to obtain 1066MHz on RAM what can I do? I don't want to underclock the CPU (the BUS)... :(Quote:
Originally Posted by tomcug

It took until today for something to go wrong, when I tried playing a video in WMP11 with other stuff. It rebooted, so I cut the voltage back to AUTO but set the FSB to 295 just to see if that still stayed stable-enough.Quote:

Notice how the vCore is again higher at AUTO?...
I think it will work but I don't think you can overclock those memories. Our motherboard doesn't like memories to run at speeds higher than 1066MHz. I'll check it with my configuration really soon.Quote:

Seeing the results that people have had with this board, I don't think it would benefit me much to go the e8500 route.
I am going to be upgrading to 4GB of ram (2x2).. Found 4gb Crucial Ballistix for $41!!! CL4! I will post how that works out..
I will be replacing my old OCZ Titanium (2 x 1gb) kit. That cost me $500 2 years ago!
If I can get 940mhz @ 4-4-4 with this Crucial kit, I will be happy.
LASTLY: I have seen people on this thread having issues with the GTX280 video cards. Is this a known issue? Should I avoid this card? How about the 4870X2 card? Any recommendations would be welcome!
LordX, if you have 1.04G revison of P5W DH Deluxe, then you don't have to worry about overclocking 45nm CPUs. I overclocked my E7200 to 4GHz without any problems with voltage at 1.4V. G40RoCkEt overclocked his new E8600 to 4GHz with 1.4V too. Even if you have older revision, it shouldn't be a problem because 1.4V isn't too high for those CPUs. About memories, it isn't any trouble to run them at 960MHz with 4-4-4-12 timings. I ran my memories at 980MHz with 4-4-4-12 timing and 2.3V without any troubles. I can also say that you don't have to avoid GTX 280 cards, they run fine with this board.Quote:

I don't think that it is worth it to spend $250 on a e8600 and NOT hit FIVE Ghz. (hell, there were some people two years ago here who hit 5Ghz with the x6800).
The only benefit besides SSE4 is the 6 MB cache compared to 4...
I will have some fun with the Ram, I got 4gb (2x2) of OCZ ReaperX ram a month ago, and they installed, but the timings SUCKED! Especially @ 940mhz... I was at 5-6-5 from 4-4-4... Wasn't happy. Now I get to try all over again with Crucial.
LordX, I don't think you can hit 5GHz with any normal voltage. I've never seen any review where 5GHz was achieved. And I don't think that anyone needs more than 4GHz. About those timings, you can set them manually at 4-4-4-12, I don't see a problem. You just need to increase voltage of course. Timings are very important with 975X, for example this is my own testing:Quote:

Setting timings manually is one thing... having the system boot... now that is what is important.
With the OCZ ReaperX 4 gb kit, it would not post unless I set it at 5-6-5.
I will update my findings with this Ballistix kit... if this works, it will be the best upgrade I think I have ever done (price included in that)...
Can you post BIOS config you used for OCZ ReaperX kit? I can have system boot with manual timings and my memories wven at 450MHz.Quote:

You know the best memory I ever found for the P5W is the G.Skill 6400HZ @ 800mhz on the memory you can run it at 3-3-3-5. The board is at it's best on the 1:1 with memory.
you can run 4 sticks of the G.Skill as tight as 2. You will see a very nice performance boost.
here is a shot with my E6600 Check the timings.

Here is when I switched to the Q6600 this is with 4 sticks of 6400HZ again check the timings.

This was near the end for my P5W DH. Soon after I reinstalled the 950 Presler that I had used originally with the board and sold the system
It was a fine board but, it was time to go. I replaced it with the P5E and it just crushes the P5W DH on every front. So I made the right move for me
Oh here is a shot of my former P5W DH with the Presler I had.

Let me tell you it was no slouch!!
I found the board to be a strong runner right up to it's limits the 975X chipset was truly amazing when it came out!!
Especially when I coupled it with the G.Skill 6400HZ
WZ
I've run through several permutations of my old E6300 settings along with a manual 1.45V vCore, trying to find some magic numbers where the Q9450 would remain stable, but no joy.
So, is ANYONE actually using 1.45V with a 45nm CPU on a 1.02G revision and can say what works?...
If I understand well, then you've already increased CPU Voltage to 1.45V but it hasn't made your system stable. I think you should try to increase FSB Termination Voltage too. This makes 45nm CPUs more stable, I've experienced it with my E7200.Quote:

I've read through this thread and done as much research as I can, and I believe that my options are pretty limited on this motherboard. I have my eye on a Q9550 and an upgrade to 4gb of RAM. I know I can run this combo on my board, but I also know I will not be able to overclock very well, if at all. That is essentially unacceptable to me. My current E6600 @ 3.4ghz would outperform a stock clocked Q9550 @ 2.66 in most games. I've thought about a Q6600, which should allow me a modest OC up around 3.2ghz which is basically just a lateral move in my mind.
My question is this. What is the best upgrade I can do on this motherboard? I am definitely going to overclock and take advantage of whatever I can to achieve optimal performance. I need a step up from my E6600 @ 3.4ghz, and I am already OK spending around $400 in order to do this (Q9550 + 4gb kit is in this price range). Is it worth upping the budget to around $500 and buying a new motherboard along with the CPU and RAM? There seem to be some well priced options (Asus P5Q-E, Asus P5Q SE+, Gigabyte GA-EP45-UD3R). Will these suit my needs? I have an external X-Fi sound card, one 8800GTS, and only 2 hard drives, so I really don't need many onboard features. I just need performance, OC-ability and stability. Also, for around $500 would it be possible to do i7? Would it be worth it?
Thanks
Tomcug - Well, I got the Crucial Ram, and put it in...
The timings I have gotten with no errors in Memtest are:
940mhz @ 5-5-4-12 for the 4Gb (2x2) kit.
My old OCZ Titanium 2 gig Kit got:
940mhz @ 4-4-4-4 (yes, I cant believe I got 4 on the last timing too!)
I am sad about the timing loss, but I need the extra ram... Sadly Vista + Fallout3 (at max settings) really DO use more than 2Gb.... I have alt-tabbed and seen memory utilization at 100%, and huge slow downs entering VATS...
I know its better to have less memory at tighter timings than more memory at looser timings, but I need the extra 2gb...
The small performance hit of the 5-5 compared to the 4-4 will be nothing if this upgrade gets rid of my issues with Fallout3 (and future games!).
I have Vista64, so at least I can see and use all of the Ram...
I will miss having one of the best timings for DDR2 @ 940mhz though... :)
This board is great... 2.5 years later, and I can still upgrade it...
e6700 @ 3.76ghz (totally 100% stable @ 40%+ OC!)
Crucial 4gb (2x2) 940mhz @ 5-5-4-12
WD Raptor 150gb
(Soon to be GTX280)
That's not a bad system at all for 2.5 years old :)
The e8600 proc is stock clocked at 3.33ghz...
If you need gaming perfomance, you can wait a couple of weeks and buy Geforce GTX295 (about ~500-550$), with a small overclock it should be as fast as two Geforce GTX 280 in SLI mode on Nvidia mainboard with their SLI chipset, so it's about 3 times faster then 8800GTS512 and four times then older versions of 8800GTS, if you use high resolutions with antialiasing. Only this upgrade can give you such big inrease of perfomance. Quad core CPU can give you 2 times faster processing power only in special programs designed for multicore computing such as video decoding or software animation.Quote:

What is more, lowering tWR timing in BIOS to 5 or even 6 makes memories much more stable. You can try this too. Right now you have 4GB of memory, so increasing MCH Voltage to 1.65V may help you too. I'm sure that you can reach those 4-4-4-12 timings.Quote:

So pushing to 940 on this ram......
I tried all those settings (my mch is already at 1.75)...
The system simply will not POST with CAS latency @ 4.
I think that you can buy E8600 and overclock it to 4GHz. This will give you better performance. If you really need quad-core, then you should buy another motherboard because P5W DH has troubles with overclocking those CPUs.Quote:

However our board has only two GTL reference voltage dividers. And this makes it quite poor at overclocking quad-core CPUs. So if you want to change CPU, then go for E8600 or change motherboard.Quote:

Hello people,
After my new upgrade (E8600), i put some screenshots of my modest overclocking.
Thanks again to my friends Tomcug and Firestarter here.

Ok, I am ordering the 4Gb Kit rated 5-4-4 @ 1000mhz...
We will see if this kit hits 4-4-4 @ 940mhz. If so, then I will be a happy dude..
Will keep posted so others who want tight 4Gb Kits will know.
