I am trying to play around with my old Q6600 G0 (VID 1.325 bad luck).
I am currently running it at 355x9. I need Vcore = 1.5450v to get it pass 20 LinX runs. Core temperature is top at 81C on air.
The other settings are
DDR2 2.250v
MCH 1.35v
CPU VTT 1.27v
ICH 1.15v

If I would like to bump the FSB a bit higher and using x8 instead. What voltage setting should I focus on?

And to OC the memory( 2x 2G G.SKILL and 2 x 2G Corsair), are DDR2, MCH and CPU VTT my main concerns? Can someone give a rough range of these setting that I should stay in between?

Thank you in advance.
