I'm having issues with this combination. Every so often the screen will go black, go white, or display artifacts like this on the screen: http://img94.imageshack.us/img94/5638/0102101125.jpg., sometimes with an accompanying buzzing. At first i thought it was a problem with the video card, but after some research this seems to be the culprit. Windows 7 runs normally but seemingly out of the blue it crashes, as described above, and I am forced to hard reboot.
I am using an Intel Core2 Quad Q9400, 2.66, with the cores running at 38, 29, 36 37 Celsius.
Gigabyte GA-EP45-UD3P motherboard the BIOS version FD
2 x 2GB F2-8500CL5D-4GBPK GSkill RAM
The sticks were in 2 and 4 since i put it together, but now I've moved them to 1 and 3. My BIOS is currently set at the following, as per the sticky:

The system still seems to be unstable. Is there a setting I've missed/messed up? I understand that this brand of RAM is not listed on Gigabyte's list of compatible memory. A rep at newegg has told me that i can RMA the GSkill RAM for a refund, allowing me to purchase another brand from Gigabyte's list of tested RAM. Would I be better off trying to troubleshoot this or just trying another brand? (I saw on another post that GSkill and Gigabyte are just plain incompatible, and that there's no real permanent fix.)
