The only problem being is the BIOS on the IB9 is pretty basic, wondering if that'd screw things up.
Will go for it slowly, probably 200Mhz increments. stress it for a few hours then see how it goes. Can see at the moment that with my Arctic 7 at 50% (and damn near silent) Cores are running at a contant 35/36, which isn't too bad I to be honest.
Will see how it goes and what happens.
