After everytime i change anything doing with memory i run memtest and no errors are found. I run prime95 and my workload temp is around 44C. Normaly my computer will restart but sometimes my mouse will freeze. I've tryed everything. Please help me out. Suggestions.

I'm using a p2.6 with ONE stick of corsair xms 512mb and a p4p800. I'm not testing with prime95 yet; I've been using pcmark2002 and have had stable at:
fsb 262mhz
DDR320 at 2.65v
cpu 1.6v

I remember someone writing that they were getting higher fsb with only 1 stick of ram - worth a shot?

nope, still getting errors.

yeah, my 2.4c oc higher(maybe around 10 FSB) with just one stick installed. i think it's memory that is holding u back. i could only get to 3.0ghz with 2 sticks of corsair pc3200c2. but with even a ddr333 infeon chip, i can go all the way to 3.4ghz stable. i still cant figure out why. maybe a compatibility issue.
