Hi Jim,

I also have a E8400 and my volts are pretty much the same as yours. What I have noticed so far is, that the E8400 goes straight to 4 GHz (with 1.37 V) and than it needs lots of volts to go further (like 1.52V for 4.32 GHz). And as Ace has mentioned earlier you need more Volts to get it prime stable. But I donīt care for prime.
But your setting is pretty much stock so I think you need not as high Volts as you have (especially for MCH).

so far Juli
