Well I was doing more prime testing and I was wrong. At 3.8ghz 9.5 multiplyer and 400 fsb. It's still not stable. I think there are more settings that I may be needing to mess with. I've played with the cpu voltage and havn't been able to find a good match. I'm at work right now but will list settings later. I'm also going to take out the 2 gigs of 800 memory and just test with the 4gigs of 1066.
