Put Board together last night, with my shiny new Q6600 G0. Love the back plates, they worked great on the 790fx board - here they don't work with my water block . Oh well, otherwise all went well.

I loaded XP Pro and did all my updates and such. Started o/c early in the AM. I am now up to 9X375 at 1.3525, FSB and MCH at Normal. Temps are great. CPU is 2-3C above ambient, chipset is 5-6C above ambient. Memory is underclocked (DDR2 750 as oppossed to 800 - will do 855) - at 2.1V 4-4-4-12 at the 2.0A strapping. No turbo or extreme.

But now I can not go any higher. I tried raising CPU voltage step by step all the way to 1.4, while raising FSB and MCH voltages each step by step. Clearly it is not heat that is holding me back - but it will not even load into XP. I'm sure this being my first time away from AMD I am missing something obvious.

Oh - yeah there is some voltage fluctuation. But I'd like to get to 3.6 stable before I flash to F8d, as it seems like there may be more tweaking there.
