Hi all and thanks for reading
I have random BSODs since I upgraded from 4Gb to 8Gb.

Before I had 2 sticks x 2 Gb KVR800D2N6/2G and had no problem.
Since I bougth 2 addional and IDENTICAL sticks I have random BSODs (once a week approx).

All sticks have been individually tested one by one with no error in 2 different Pcs. with Prime95 and memtest 4.0.

My question is:
Is there some kind of incompatibiliy with 4 sticks of 2Gb Kingston DDR2 800 Mhz KVR800D2N6/2G in mobo P5Q SE?
I have read someone saying that they cause crashes when they are all set together in P5Q SE.
Is this true?

Thank you and best regards

p.s.
My system:
Win7 64bit SP1
P5Q SE (bios 1005)
XFX ATI HD 6870 1Gb DDR5, drivers 12.3
8 Gb (4 sticks x 2Gb Kingston DDR2 800 Mhz KVR800D2N6/2G)
PSU 700W Tacens :pfff:

Even though you bought modules having the same part number, they aren't necessarily identical. Are the chips identical? Loosen the timings a bit and it might resolve the issue.

Start by increasing memory voltage a bit (change it from Auto to 1.9v) and then run memtest86+ for several hours.

I fixed this some months ago. The mobo Asus P5Q SE was to blame. It was damaged.
Thanks for your help
