Okay, so I understand you right when I say that there must be a difference when I rise the Vcore from 1.1V to 1.2V.

Note that the CPU are working at there limit when I messure the wattage.

All eight cores are at fully load with QMC workunits and on my other systems i can see a difference when I change it only for 0.05V.
