When installed the memory is set to run at 1333 MHz, i have gone into the bios and manually changed it to 1600 but then that changes the timing, which i manually set back to 9-9-9-24-2N, but the system fails Prime95 after about 2 minutes, I am very new to this. Any suggestions?
Download http://www.memtest86.com and put it on a CD (wont work on a DVD). In BIOS, set your optical drive as the boot drive and boot to memtest. See if you can go through a full cycle or two to make sure it is the memory that is causing the Prime95 fail.
