Hi.

I have MB GigaByte MA790X-DS4 (BIOS ver. F6) and Phenom X4 9950. The MB has 4 DDR2 slots.

Currently I have 2 2GB DDR2 800 Modules from GoodRam (they look similar, however I've bought them not together).

I've tested my PC with only one module and it worked stable (I've tested both RAM modules). However when I use 2 modules (doesn't meter Ganged or Unganged mode) - the system looks unstable. And I often could get BSoD while gaming or viewing HD online videos.

What could you recommend me in such case? Update BIOS? By another RAM?

Thanks in advance.

P.S. The OS is Win 7 x64.
