I think a lot of it is luck. In the link I referenced (http://forums.vr-zone.com/showthread.php?t=88306) the guy got a Q6600 to 400FSB on less than 1.4 vcore. That's nuts.

I think it's really just luck of the draw. If you get good parts, you can get great OCs, if not... Oh well.

I should've gotten an E6600. :P
