Rig's in the sig. Just got a q9550 today and immediately got it to 3.4GHz (8.5 x 400FSB) on air with no changes in voltage. Temps are around 50C average from IBT and Prime. I'm happy since the speed is still 200MHz better than my e2180 OC, but i've been trying to do a little experimenting to get it to 3.6 or better.
However, I've tried just about everything to get it past 420 FSB but no dice. No change in MCH (+0.3), FSB(+0.3), DDR (+0.2), or Vcore (1.32) seemed to get it to boot past the vista loading screen. I've got most of the basics down, like disabling speed step etc. I'm not gonna bang my head against the wall because I'm guessing it's my ram (ddr-800). Or am I not trying something?
