i was trying to figure out why my chip wouldn't do 3 ghz anymore after switching from 2x1 gig crucial to 2x512 bh-5. set jumper so i could get 3.4 volts to my ram. then noticed chip wouldnt do 3 ghz anymore.

figured it might be the instability caused by the jumper.

switched the jumper back and now the chip ran 10 hours of small fft prime with no error.

anyone else do any testing of this sort?
