very nice

After my post above (thanks for the replies) I decided to ditch the overclock and reduce it somewhat...

@ 3.45 gig

Vcore = 1.51V, Vmch = 1.45V, Vfsb = 1.4V fsb, Vsouth=1.6V

Prime stable

@ 3.31 gig (so not that much lower)

Vcore = 1.41V, Vmch = 1.25V, Vfsb = 1.3V, Vsouth = 1.5V

Prime stable

thats a lot of extra volts for not much extra overclock - so sticking to no.2 I think
