Default VCore

I'm running my Opteron 170 at default VCore (1.31v). I lose a little CPU speed, but the idle temp drops to around 27-28C. Running dual-Prime the load temps are 43-44C. That's a lot more acceptable to me. I think the IHS is not making good contact with the core. Still, I'm not going to remove the IHS. I'd rather keep everything intact, in case I decide to sell the CPU later on.
