i got lucky on mine, took about 45mins to find the point at which it's p95 stable w/o a voltage change. you can see the setup in my sig, and it was unstable at 234 while playing games (was in the middle of star wars galaxies getting chased by something when i locked up --- no bueno), but hasn't had a glitch and has been thoroughly tested with F@H, p95, and various types of games.
good luck to you and let us know how progress is coming along!
