Just thinking about auto vcore for a minute ...

I had a little problem with this Opty system at one point thanks to my being a little over enthusiastic and sloppy with my TIM. A little had gotten onto the SMS caps on the CPU module. The result was unstable (and very high) core voltage when using the 'auto' setting (must have been on the feedback circuit). A careful clean (I used Artcic Clean) and the vcore now both reads much lower and is rock solid stable.
