ASUS P5W DH - Problems + Fixes Thread

[firestarter.pt]

I want to upgrade from 2 Gb to 4 Gb with this board.

What memory kit would you recommend me considering i'm using an E8600 @ 4.1 Ghz 24/7 (10x 410 fsb - DDR820)?

[Yolanda]

Any two PC2-6400 2GB cheap modules, there are a lot of from Samsung, Hynix, Patriot and others, you will get 5/6-6-6-18 timings by Auto setting.

[firestarter.pt]

I found a good deal for 2x 2048Mb DDR2 Corsair XMS2 Dominator PC2-8500 (1066) (40€), i'll post the results later when I have time to test them. I still have hope I will be able to beat 410 fsb and/or at least use 5-5-5-15 timings :P

NEWS ABOUT WINDOWS 7 x64 Release!


Just to tell that with bios 2901 the BSDO bug at the begining of W7 X64 installation was solved!

So, finally can install with sucess my W7 X64 release.

About drivers all is avaliable to install via Windows Update and works very well!

People that want install W7 X64 , FIRST UPDATE BIOS TO 2901.

Seems that 2901 fix the w7 x64 bug too.

Good races!

[PaVi90]

The support by Asus to this motherboard is wonderful... after years still new BIOSes! Great!

[mikepaul]

Ummm, 1.02G users are probably not applauding BIOS support very loudly...

[pc1x1]

Hiya, I haven't booted yet, and thanks, it took alot of digging, hehe.

I will be booting my PC this weekend, sleeving took ages to do! And Ill flash to the latest bios and well figure out if I can run the Quad Core.

I am on a 1.02g, so this should be interesting , also will try to Install Windows 7 RC1.

I'm very interested to hear how you do with this chip on the p5w dh and the 2901 bios, particularly with any 64 bit windows installs.

I have the same cpu related questions that you asked in this previous post

Thanks for the link in that post to the related thread at social.technet.microsoft.com, very interesting and eye opening. I had gotten the impression from the below Asus blurb that other than the limitations a
Q9550 would work fine. I sure haven't seen many success stories in these threads so far, but from what I can tell one guy with a Q9650 and one guy with a Q8600 report success with Win 7 RC 64 on a p5w dh.

Support information for 45nm CPU (from FAQ)
http://support.asus.com/faq/faq.aspx?SLanguage=en-us
...
I’ve recently bought a Intel 45nm Yorkfield CPU Q9650. When I put it onto my P5W DH deluxe, everything is perfect, but L2 cache size shows 0 KB in BIOS. When I check it in CPU-Z, the problem persists. How do I re-solve it?

Due to chipset limitation, i975X chipset is not able to support all the features of 45nm CPU. The following is a list of the limitations:
1. VT function does not work.
2. The maximum FSB is capped at 1066MHz.
3. 0.5 CPU multiplier is not supported.
4. L2 cache size is not recognized correctly. However L2 cache is still functioning.
...

I'm currently running an E6600 at stock speed with bios 2801, Win 7 RC 32 bit and Vista 32 bit.

I'm interested in a quad core chip like the Q9550 or Q8400 for eventual use with 64 bit Win 7 (will start with Win 7 32 bit) but it sounds like I might be better off buying a new motherboard?

[GAR]

wow people still use this board, i remember this was one of the best boards for its time!

[G40RoCkEt]

GAR,

I always update the hardware but the P5W DH always be in safe.

For me was the best 2006 motherboard and i still love it.

Great extra bundle and amazing support including 45nm processor!

Here in this P5W already pass E6600-E6850-E8500 and finally E8600 (with a little oc).

And i have to say that with Windows 7 Ultimate 64 bits this rock more!

Everyone should be try this SO in P5W.

[ntvh]

Yes this board is ROCK. will try for Win 7 after come back from camping.

Hello, recently i've started having trouble with booting my mobo, the thing is when I first turn it on it doesn't POST what i've found out to work is turn it on and then on back again and usually it POST but sometimes it doesn't, when it doesn't I switch off the PSU and make it rest for like 10 mins or so and the turn it on again and it will boot.... :S any ideas??

My specs

CPU: Intel Core 2 QUAD Q6600 @ 3 GHz, 333x9, 1.25V
MOBO: Asus P5W DH Deluxe, BIOS 2801
RAM: 4x2GB DDR2 800MHz 5-5-5-18 @ 667 MHz, 1.8V
GPU: XFX Geforce 9800 GT
PSU: OCZ GameXStream OCZ600GXSSLI ATX12V 600W Power Supply 10

the same thing started happening to me too..i get stuck too when i m in the bios setup,i m still looking for a solution.

[Aerics]

Good morning together.

I tryed so many times to overclock my cpu, but i can only reach 3,15GHz.

I tryed everything i know, but if i overclock over 3,2GHz i need much more vcore. I get it only on 1.55 vcore stable. Everything above nothing happens if i change the vcore or mchv, i get only errors.

I use water to cooling my computer and the normal ram frequenze is 800MHz.

Maybe i have some misstakes in my bios confige or my cpu really sucks.
I Hope someone can help me and find my misstake.
And sorry for my bad english

Are people using the current Vista versions of these 975X Express utilities with Win 7?

http://www.intel.com/support/chipsets/sb/CS-021728.htm

Intel Chipset Software Installation Utility
Intel Matrix Storage Manager

Any idea if upcoming Win 7 versions can be expected?

[Yolanda]

These programs are for Windows XP and higher, so work fine in Vista and Windows 7 also.
Download latest versions from Intel site, you can choose newest Intel chipset, all versions are the same and for all chipsets.

However you can not to install Intel Chipset Software Installation Utility in Vista and Windows 7, because it's simply rename chipset devices in Device Manager to their real names, Windows 7 already know all i975 chipset component names.

[SS_The_Demon]

I have a small problem here with this board. Hope someone can help.
Getting 333FSB is no problem at all, but 350 and upwards is a major problem, but only during booting. I have on some occasions reached 400FSB, and as soon as I reach Windows, it's perfectly stable. But the problem is to get it to boot at any higher than 333
Too bad, cause I know the CPU will do 3.6GHz on 1.3V Vcore (1.3 selected in BIOS, not measured 1.3V, maybe even less than that. So, any suggestions on what to try?

Getting the board to successfully turn on (POST?) or getting it to load windows without locking up or blue screening?

[SS_The_Demon]

Getting the board to successfully turn on (POST?) or getting it to load windows without locking up or blue screening?

Are you asking me or? But yes, getting the board to POST @ 350FSB or higher is a big no-no, I just get a black screen. Have to turn the comupter off using the power button, then turn on and get the "overclocking or overvoltage failed" message, and enter BIOS. MCHV at 1.65V and FSBTV at auto and 333x9 is my current 24/7 setting. BTW, what does the FSB Termination Voltage do? I haven't found any use for it as of yet.

Tried booting at 360FSB with 1.65V MCHV, it did POST but failed to load Windows. Trying 360FSB with 1.75 MCHV it doesn't even POST. I'm thinking that it's some kind of overvoltage protection, cause I read back in 2006 when the computer was new that you should disable any such protection. But that setting doesn't exist in the BIOS does it?

Sigh...Really could use a little higher FSB, CPU is limiting my GTX260 like hell...maybe I just should get a new board...but I don't want too, love this one too much except for the low FSB wall...

[Yolanda]

You have 3.6GHz 65 nm CPU stable at 1.3V only? Are you sure?

[Falkentyne]

Set the vmch to 1.65v and the FSB termination voltage to 1.40v.
Then try your 360 fsb.

And I don't think you're going to get 3600 mhz stable on a B2 stepping E6600 stable at 1.3v I think that's part of the problem. Isn't the DEFAULT voltage for that chip 1.35v? You're overclocking the chip and running it at lower than default voltage....

Try 1.45vcore and then see if you can post at above 360 FSB and load windows.

How did you get it *stable* at 400 FSB before? You said that you made it boot at 400 fsb and it was stable, if it managed to boot. How'd you do this?

I'm 100% certain it wasn't stable unless you're watercooling or on subzero....

[Aerics]

Nobody have a tip for me?

[Yolanda]

Aerics Try to set memory timings to SPD, our board likes it more and overclocks then higher.

[SS_The_Demon]

Set the vmch to 1.65v and the FSB termination voltage to 1.40v.

Thanks, will try. Doubt it will work though. But yes, first time I overclocked my rig (which was the first time i overclocked BTW) I used 1.45V vcore, 1.45V selected in BIOS that is. This was end of November, 2006. Since I didn't want break anything, and I didn't get any noteworthy performance boost either, I used stock settings instead. For some reason I can't remember, several months later I decided to see if I could use a lower vcore, and I ended up selecting 1.3V in BIOS. Unfortunately, I don't have a screenshot of 1.3V vcore, but if I ever get it too boot again at 3.6 I will DEFINATELY take a screenshot
Here's the screen showing 1.45V vcore, ignore CPU-Z as it shows the wrong value. But AiBooster should display the right value, considering vdroop or whatever it's called.



And here's another screen showing 3GHz @ 1.184V full load according to CPU-Z, 1.225V selected in BIOS. No vmods have been done to the board, only changed the thermal paste under the NB, so I guess the lower voltage indicated by CPU-Z is because of vdroop? Also, notice in Core Temp that my VID is 1.2625V, not 1.35V as you suggested.



However, worth noticing is that when I ran 3.6GHz, I had the window open in my room (Finland is cold), so I guess my room temp were somewhere around 5 degrees Celsius.

How did you get it *stable* at 400 FSB before? You said that you made it boot at 400 fsb and it was stable, if it managed to boot. How'd you do this?

I'm 100% certain it wasn't stable unless you're watercooling or on subzero....

Max voltage on MCH, FSB Termination and ICH (you shouldn't overvolt the ICH should you?). I wrote the settings down so I wouldn't forget them. Stability was tested using Orthos for several hours, can't recall exactly how long I ran it though, probably around 8 hours or so (Yeah I know, TAT puts a heavier load on the CPU, but as long as I can play any game without crashing or passing 65 degrees on the CPU I'm happy). But what happens 99% of the time I try to use the same settings as before is that I apply every setting as they should be in BIOS eg C1E, EIST, Hyperpath 3, Virtualization etc gets turned off, voltages changed and so on. But once I hit F10 and press enter the screen goes black just as it should, the LED on my screen turns orange as it should, but it doesn't turn green again.

After that I turn the computer off using the power button, turn it on again (not resetting CMOS or anything BTW), and then I get the oh so annoying message:

"overclocking or overvoltage failed"
press F1 to enter BIOS
press F2 to load default values an continue

Thing is, I remember reading somewhere that you should turn off any overvoltage protection. Can you even do this?

BTW, sorry for the long post, just trying to give you as much info as I can because I want more FSB on this thing. And I know it shouldn't be impossible because I have seen several people run the board @ 400FSB 24/7, some 440FSB and over as max, someone even hitting 500FSB+

EDIT: Tried your settings, with various vcore frequencies as well. Was about to try higher vmch and/or fsb termination voltage, but a strange thing happened. After one of those failed overclocks, I was at the point where you choose either F1 to enter BIOS or F2 to load default and continue, naturally I chose F1. So the screen goes black, as it should do for about a tenth of a second before the BIOS screen pops up. But then it stays black, so I'm thinking "hmm that's strange, never seen that happen before", so I turn off the computer, turn it on and then the REALLY WEIRD STUFF begins. The screen is really weird, I should have taken a picture but I was too lazy and too shocked, thinking I just destroyed the board. Anyway, the screen looked something like:

-________________________E6600_____________________ _____
__________________________________________________ ______
__________2.40GHz_________________________________ ______
__________________________________________________ ______
___________________________________LKJASHD4346____ ______
____KLJF0987______________________________________ ______

and so on. At this point I didn't like it at all, and it only got worse. Turned the computer off again, turned it on and what do you know? Same thing, only this time the screen seemed to scroll down, and some of the letters and numbers on the screen (the few that appeared) seemed to match my harddrives. After hitting F1 the top bar turns blue, but the rest stays the same. So I'm thinking "so this is what Asus beta BIOS looked like :P ", and also I am noticing that the clock is visible as well, but seems to skip every other second or so. So I reset the damn computer yet again, and this time the screen looks normal, so I enter the BIOS, everything looks normal here as well, apply my settings for 333FSB, boot into windows and here I am, somewhat shaken still, cause I'd rather not spend any more money on a new or second hand 775 motherboard, considering it's getting obsolete.

Anyone else ever seen anything like this? Seems like I got a very good CPU, but probably the worst P5W ever made
How annoying is that?!?!

[Falkentyne]

Does the board still boot correctly if you clear the CMOS with the jumper (after unplugging or turning off the power supply switch?).
