I recently bought a Q6600, GO stepping and it doesn't seem to like overclocking in the slightest. I can't get past 3GHZ and whenever it is overclocked the system feels pretty unstable, even though Prime says it's fine. I tried 1.45vore for 3.1ghz and the system wouldn't even post, but it'll post and run battfield fine at 3ghz on 1.3 volts...
Is this a power issue I'm looking at? Even my old E6420 got past 3ghz and these GO stepping are supposed to be able to reach at least 3.4 with around 1.35-1.4 volts
