just bought my 3570K, and im now doing test on under/overclockings,

when i use voltage Manuel mode at 0.800V, the CPUID shows a voltage of 0.792V and estimated 16.69 W

when i use voltage offset mode at -0.290V, the CPUID shows a voltage range of 0.544-0.560V and estimated 31.45W when full load.

ok i know the power should go down when voltage decreases, but must be somewhere is wrong. is anyone know?
