so basically your best chance at a good OC is the 6420, if your on a budget.

Using P5B 1.04G with 1202 BIOS, using all auto voltages except 2.1V Vdram, I pused the FSB up to around 375 (my Corsair 6400 still well below its rated speed) before it started giving me problems. So, I upped the Vcore, the Vnb, Vfsb, all the settings up to 2nd highest. Got to 380, but thats about it. Wont go any higher.

I heard about some overclocking "hole" between 360 and 400, and that 1333 bootstrap takes effect >400, so took the big leap of fait and tried 401 and 410 to no avail.

Perhaps reached the limit of this little CPU? Tried all over with 6x multiplier, and got to about the same place, 380 fsb, no more.

Tried desperately randomly toggling settings like static read control, and TM... nothing.
Anything obvious you guys can think of that could be causing this?
