I'm messing about overclocking my 3870x2's & trying to find the sweet spot for the IOH Core voltage. If I set auto in BIOS I get 1.3~1.4v ish so thought I'd go check the x58 datasheet http://www.intel.com/Assets/PDF/datasheet/320838.pdf as I thought 1.1v was the default & 1.4v looks like a lot.

I think page 211 table 15-11 sheet 1 & 2 are what I'm looking for but cant find any maximum voltage or absolute maximum can anyone point me in the right direction or is there simply no maximum!!!
