I'm getting there...

I did an 8 hour prime95 v2.54 large fft run with my G0 Q6600 L725A903 @ 450x8. I brought the CPU VTT voltage down to a level I'm more comfortable with. I found that it's all in the GTL's. At first I was trying using the 67% rule, but after bumping them up progressively (leaving everything else the same), I went from a few minutes before failing large fft to eventually settling on 116/116/117, which allowed the 8 hours without failing.

8x450fsb with Tuniq Tower 120 and a TT 12cm fan at max speed over the NB/PWM area.
