Stability Issues - ASUS P5Q SE2

[Cratzky]

Hello!


Im running a computer with this Asus P5Q SE2 motherboard and 4gb of Corsair TWIN2X PC6400 DDR2 2GB KIT CL5 memory.

In other words, i got 4 memory sticks.

I cannot run memtest without errors with any more ram then 1 stick.
Ive tried swapping all 4 memory sticks around to check if some memory is failing but with no success.
When i use 1 memory stick (does not matter which one) i get no errors in memtest. but with anything else then 1 stick, i get errors.

Worth mention aswell: when i try installing windows7, the install is extremely slow, it can take up to 10min before first screen pops up after loaded the cd.

Also when i get a BSOD , the memory dump takes ages. I mean really.. it takes approx 10min for the dump to count from 0% to 100% before it restarts...

Any ideas?

Here is my computer specs:

Asus p5q SE2 bios rev 0702 (which is very odd , it seems that this bios does not exist on asus homepage)
Intel quadcore q9400 2.66ghz
Corsair TWIN2X PC6400 DDR2 2GB KIT CL5 X2 (4GB)
Creative X-Fi xtreme gamer
Windows 7 x64
Corsair VX550W PSU
XFX Geforce GTS 250 1gb

EDIT: I get same issue in windows 7 x32 aswell so it has nothing to do with that i think...

I had stability issues with alot of random bluescreens when the memory voltage was set to auto which according to CPU-Z said to be 1.8v, so i changed it in bios to Manual and set it to 1.9v, but CPU-Z still reads 1.8v.. But the issue seems to have almost disappear... But sometimes bluescreens can occur at random situations so problem not solved..

Alright, i was thinking i should share this information.

I managed to get it stable , running with 4 memory sticks etc...


Here is what i did:

I just couldnt get it stable at default settings, so i changed _Everything_

This is very odd, but its very stable now, i havent had a bluescreen in a week.

Also i installed new cooling with this setup since im running the cpu at 2.93ghz now (2,67ghz stock) and the memory at 877mhz instead of 800mhz (stock)

New cooling: 2x zalman zm-f3 120mm chassie fans, 2x coolermaster 120mm chassie fans, xigmatek achilles 120mm cpu-cooler

I plan to take the cpu to 3ghz, which im goin to soonish..

Its odd that the computer works better stabilitywise then with default settings..
But a little extra performance isnt bad

Hope this helps for other people with p5q series mobos with stability issues like random lockups, random bluescreens etc..

Questions? just ask

Good you got it working. If you didn't update your bios to the newest revision, you should.

I know, i struggled with the computer for weeks and was running out of ideas so i started to read OC threads and tried that and it magically got stable...

Im running a bios , that isnt on the asus homepage. This is also very odd since it came from the retailer with this bios..
