Blue Screen

[melp334]

Ran computer for about 2 years, then started to get blue screen.
I have latest bios, all drivers up to date.
If I use default settings in bios computer crashes.
If I reduce bios ram speed from Auto to 667 it will run all day long.
If I leave settings 0n Auto and remove 2 sticks of ram leaving 2x1Gb it will run all day long.
Ram actual speed is 640 800
All 4 sticks have cooling pannels on them.
CPU temp 23c Scythe Samurai Cooler 92mm Fan Artic sylver 5 Paste.
Ram temp 35c
Enviro temp 28c
These Temps are at idle.
Ran MemTest all cards are OK
Can anyone help.
Thanks

I had a similar problem with an Asus P5 board(think it was a P5N), after a year or so. The fix for me was one extra click of northbridge voltage. That seemed to allow me to run with all 4 sticks no problem.

It's also worth noting that the performance difference between running the ram at 667 vs 800 is basically non-existent. So failing all else, that fix will do you fine.

Up the DRAM voltage and the northbridge. Have you made any serious driver changes recently? What is the bluescreen error? You have a minidump of it?

Hi No I have not installed any drivers recently.
I have increase dram voltage 1 click, itr has ran for 20mins without crashing on cod4.
That might have cured it.
Thanks for your help.
Best regards.
