I'm 4 hours prime stable. This is the best I've had all day. Sadly, the timing are really loose. I'm hoping that I can get the timings down to something like 4-4-4-12 so I can game w/o any real downside. If I get 8 hours, I'll up the FSB. I'm hoping I can get 4.0ghz 24/7 stable (445x9 or 500x8) although I think my voltage will stop me. I'm at 1.55v now, though I know 3.825 will be stable at that voltage.
