[justapost]

with 04/15 its reading 1,440v in cpuz and 1,436v with dmm at 1,4v stock vcore btw.. so cpuz is indeed pretty accurate, but there are these certain discrete steps.. 1,44v, 1,456v and so on..

you can measure vcore at these points marked red...

Abit more inaccurate here.
Bios: 1.3125V
CPU-Z: 1.312V
DMM: 1.355V

Found points for NB voltage (green).

Bios: 1.14375V
DMM: 1.142-1.143V

Testing voltages with 4pin vs 8pin rail:

Bios: 1.3125/1.14375 (cpu/nb)

4pin/idle:
CPU-Z: 1.296V
DMM-CPU: 1.326V
DMM-NB: 1.139V

8pin/idle:
CPU-Z: 1.296V
DMM-CPU: 1.327V
DMM-NB: 1.138V

4pin/load:
CPU-Z: 1.312V
DMM-CPU: 1.353V
DMM-NB: 1.139V
P-Tuner 12V1(max): 13.5A/12.04V
P-Tuner 12V2(max): 0
DMM-12V1: 11.92V

8pin/load:
CPU-Z: 1.312V
DMM-CPU: 1.351V
DMM-NB: 1.139V
P-Tuner 12V1(max): 7.2A/12.09V
P-Tuner 12V2(max): 5.4A/12.09V
DMM-12V1: 12.04V
DMM-12V2: 12.05V

Using 8ping results in more accurate 12V1 P-Tuner readings.
Beside the 0.03-0.04V higher vcore (which is huge isn't it?) everything else seems to be in range.
