People, nobody tried to measure a VCORE before and after MOD by a multimeter? Or everyone trust indications CPU-Z/Asus Probe/Speedfan/etc.

On my motherboard the real voltage is much less, than is exposed in BIOS:
(all voltages in idle)
BIOS: 1,425 CPU-Z: 1,38 Measured: 1,27
BIOS: 1,7 CPU-Z: 1,64 Measured: 1,44
