My recent switch to C2D E4300 (from x2 OCed to 2.6)

Not 100% sure on these Intel based boards, but from what I've been seeing, these cheaper priced boards tend to skimp on the chipset cooling, which becomes the limiting factor for OCs. On my 650i chipset MB, the NB is insanely hot....hotter than any other component I've ever touched. Its definitely limiting my OC, but I don't really want to spend $25-30 on a good aftermarket cooler for it. I did install a $12 Antec SpotFan over top of the NB heatsink and I picked up 25MHz on the FSB and 100MHz overall.

O M G i cant agree with you anymore on this statement. My 680i gets EXTREMELY HOT. So hot i need to jump it on water.

But to the OP. Maybe you just got a bad CPU. I hear intel's are getting really crappy with OC. Expecially there new batches with F revisions. I like to still believe each chip is like a finger print. You can never duplicate the same max results, only get lower, or higher on another chip.
