"ASUS P5Q Deluxe discussion".

[BdON003]

I am having real trouble getting my system stable at 450x9. I have P5Q-DLX with E0 E8400 and Mushkin Redline DDR2-1000 2x2gb ram. I have been testing a lot at this speed and just cannot pass the prime95 blend test. My best was around 2.5 hours with no fail. I ran Linx for 150+ runs/8hrs+ and small fft for 6h+ so I am pretty sure it is not my cpu. I am using the 1708 bios and I am wondering if it is my board, ram, or possible at a dead-spot. Here are the settings of my longest blend run:

I've tried DRAM voltage from 2.04 to 2.12 and 2.08 gave me the longest stability. I've also tried NB voltage from 1.34 to 1.4 and 1.36 gave the longest stability. My memory is rated in CPU-Z as 5-5-5-12@500MHz@2.05v so I changed the memory timings to 5-5-5-12 but it seemed to hurt the issue because I could only last blend for 2h and with 2.1v. Thanks for any help.

Try increasing your FSb VTT to 1.28-1.30, lower you CPU voltage but only after you get stable. Try this for your NB GTL .85/NB Voltage=your NB GTL, I think it's either your FSB VTT or your NB GTL that is holding you back, that was the problem in my case. Then you can setup your CPU GTL's, do some reading in the forums on this, I promise it will help. Also, run OCCT, I find it;s better for overall system stability, and it will only require a 1 hour run. I have now got my system completely 100% stable and rockin. Here is how my bios looks.

[BdON003]

Thanks for the response, I will give that a shot when I have some time. BTW, I also forgot to mention that every time the blend test fails, it is always core 1 (counting from 0). I realize the GTL voltage reference for 1/3 might help but I'm not sure what to set it at and like I said, I think the cpu is stable.

On my board, Core1 in Prime relates to core0 in my Bios as to GTL's, my board defaults to .630 if I am not mistaken for 0/2 and .670 for 1/3. I would try .635 for 0/2 and work your way up if needed. Mine both ended up at .675. Go figure.

Yes for the Quads it always seems to end up at .635 or .675 for both, for dulas it's the opposite. I found it easier to find my GTL for the .670 ref and then set the .635 on auto and let the MB do it. NB GTL is a little trickier as we do not know what the ref is. It could be anywhere from .8-1.0 I chose .85 as a starting point and it seems to be bang on.

[x3mgamer]

lower vcore with new bios confirmed.

1 step vcore less

[x3mgamer]

ok after dropping vcore 1 notch and running prime95 small fft for like an hour the system bluescreened with this event viewer log:

Fault bucket X64_0x1E_usbhub!UsbhReferenceListRemove+f0, type 0
Event Name: BlueScreen
Response: http://oca.microsoft.com/resredir.as...eListRemove+f0
Cab Id: 0


and windows commented on it with:

Problem caused by USB driver

You received this message because your universal serial bus (USB) driver has caused a blue screen error. This type of error means the computer has shut down abruptly to protect itself from potential data corruption or loss.

wtf ???


update: ran prime again and it bsod after some 20 mins, less vcore not stable, going back to my old setting

[Darkman Returns]

Still testing the limits of my new build myself but so far I've had to go up one notch on vcore for previously stable setting with 1805 BIOS.

[vrdublu]

Does anyone know what "CPU MARGIN ENHANCEMENT" does???

[Leeghoofd]

It enhances or say should enhance OC'ability of the newer quads (Q82 and co).... most Q9450 and co users use Compatible mode as it is/was the most stable... (no idea bout it on the latter biosses then 15XX though)

Also guys new isn't always better, with my E8serie CPU's and the Q(X)9650 1406 was a darm good bios and the newer versions ( tested till end of 15XX series, then I sold all the boards) didn't bring much here... Give 0803 or 1406 first a try, if it doesn't solve ya issues then try a more recent one. P45 is finding the sweetspot between the voltages, more isn't always better there. And it's not a good idea to just copy templates and put them settings in the bios. As some boards seem to require beefy voltages while others can do with way less... you have to experiment one step at a time, otherwise you will get lost !

hi. i am new to the forum although i have been reading it for many months now. a great forum and thanks to all for all the information which has helped me enormously. however i am unable to get a little bit further. i am wanting to reach 4.0ghz for 24/7 use. i have been prime blend and small fft stable for 12+ hours with auto settings, but i am wanting to set manually. i do want the settings to be safe for 24/7 use. i always fail the blend test. small fft seems to be ok, so i assume it is my fsb which is holding me back. increasing vcore beyond below value has been of no real benefit in stabilising my o/c.

please read full specs in sig.

with the bios settings below i have manages to stay 2.5 - 3hrs blend stable before failing.

I would definately say that your NB is causing the Blend fail. Try this formula to setup your NB GTL's, keep in mind that anything from 0.8-1.0 could work, and this is what worked for me. 0.825 / NB Voltage(1.28) in your case. This should land you pretty close if not right smack where you want to be. I have found that Vista's built in Memory Tester works great for checking problems without crashing out of windows. For Setting up your CPU GTL's theres a great thread on the subject in these very forums, it's a great read and very helpfull. Also your CPU PLL will help your CPU breathe, don't be afraid to increase that higher as your FSB increases. Leeghoodfd also makes a very valid point, this is hopefully a step in the right direction for ya, GL.

I had a litle time so I made some changes to your setup, try it and let us know how you made out, make subtle changes if you're not entirely stable.

nope you swap the chips... it's easy no worries

You wolfdale guys are using a crapload of VTT. I am prime stable 4.5ghz with 1.360Vcore and 1.16vtt

You really shouldn't need more than 1.20-1.22 for even super high clocks IMO

[BdON003]

P.s. has anyone checked the voltages on the latest 1805 bios, my multi meter is on the frits, I need to know if the voltages are what the bios says they are.

I had no luck with these suggestions. With FSB Term Voltage at 1.28 I was only stable for an hour and with 1.3 it froze within minutes. I also tried 0.630 and 0.635 for NB GTL Reference and had no luck. I also tried 0.670 for CPU GTL Reference (1/3) but that was bad, too.

I think I will either try a different BIOS or just push on to 500FSB if there are no more suggestions. I normally wouldn't do the latter without first being stable where I am at but I have tried everything except messing around with the CPU GTL Reference, which, as I'm writing this I think may be a good idea to start doing.

[RAdoxx]

I want to get my two samsung drives to run in raid 0 (is this even correct english? haha) but I have a question first.

Will I lose the raid each time I format C: or will it be saved by BIOS? Just like the BIOS-settings?
I'm going to have to install raid-drivers by pressing F6 at the beginning of the WinXP install right? And that's it?

EDIT: What if I flash BIOS to a newer version?

[YMAA]

Formatting C:\ doesn't erase a RAID array, no (assuming you created your array through the motherboard RAID controller and not in Windows).

I'm afraid if you can't get stable without setting up your GTL for CPU and NB at your current fsb, the likelyhood of being stable at 500fsb are next to non. Try different multiples of what I had suggested.

[vrdublu]

You wolfdale guys are using a crapload of VTT. I am prime stable 4.5ghz with 1.360Vcore and 1.16vtt

You really shouldn't need more than 1.20-1.22 for even super high clocks IMO

Would you mind throwing your bios settings up ??? Increased FSb requires higher VTT, tried lower myself but getting reboots and such.

[Leeghoofd]

I had no luck with these suggestions. With FSB Term Voltage at 1.28 I was only stable for an hour and with 1.3 it froze within minutes. I also tried 0.630 and 0.635 for NB GTL Reference and had no luck. I also tried 0.670 for CPU GTL Reference (1/3) but that was bad, too.

Why don't you try 445FSB and 1066Mhz on the rams... also for the ram plz set TRFC ( row refresch Cycyle time ) at 55 for 2GB dimms.

And don't put in so high FSB Tern and PLL voltages. Learn how your own CPU's responds to volts.... you tell the story yourself : 1.28 : 1 hour, 1.3 1 minutes : so lower the value then instead of increasing... think logic !

And if you try tweaking the GTL values (only because it's not stable in Blend ) just trying 0.630 and 0.635 is far from enough... with a quad take your time. A Wolfdale almost doesn't need any NB/CPUGTL tweaking till 550FSB stability (unless the CPU is totally overfed with volts)

In your case I would drop down to 400FSB and learn how to setup the CPU. Get it stable with the lowest values possible of FSB and PLL : testing with prime SMALL FFT !! no IBT plz. Then work ya way up to 425FSB, restest the cpu again. And so on... you guys are all aiming too high from the start and then get lost, copy templates with settings that ( in my humble opinion ) are overkill. And then finally you get frustrated and ditch the board.

P45 needs proper volt tuning, same for the 45nm CPU : MORE VOLTS ISN'T ALWAYS BETTER !!

Start off with FSB Term 1.2, PLL 1.5 and NB Volt at 1.2 at 400FSB/1000mhz ram and most ram timings to AUTO besides 5-5-5-15 TRFC 55, Static Read Disabled.

So i'm in windows with this settings, but prime won't run on tho cores. I don't know why...

Here's the pic:


Thanks for any advice

PS: Rebooted, 1st try loading windows failed, i got a bluescreen, 2nd try i got to windows, and i'm still in it. Some changes are definetly required (i think), thanks for any advice
PPS: Started Prime (worked for all cores), but after a few seconds bluescreen...

lower vcore with new bios confirmed.

1 step vcore less

Sow the vcore is lower. And is it stable?
