Hi!
My parents recently upgraded their old PC with a used Q9550 and 8gb of DDR2 (4x Corsair CM2X2048-6400C5 @ 800MHz). The board is a Asus P5Q-E running Windows 10 Pro x64, GPU is a Zotac GT440 Synergy Edition V2.
Here is the issue: the PC freezes with all the 4 sticks of RAM, but when using only 2 everything is fine. I ran several passes of memtest86+, which showed no error at all. I tried swapping the order of the RAM, mixing it with Kingston Hyper X RAM (the RAM before the upgrade). Any of this resolved the bug. I tried a different set of dual channel RAM and it was working great.
Interesting fact:
The Windows event viewer showed up an error 14 relating nvlddmkm at the same time the freezes happen, but the error is gone since I updated Nvidia Drivers today (error gone but problem is still here).
Any suggestion would be very appreciated.
I'm currently trying the mix of Corsair-Kingston RAM with the new graphic drivers. It seems to be stable, I'll update the post if something happens. I might underclock to 667, it may improve stability?
P.-S.: I'm sincerely sorry for my bad English
