CPU voltage problems

Specs: Win 7 Ultimate 64-bit sp1, 3.4 GHz Phenom II 965 BE/ 4087 MB DDR2 1066
Running a 965BE @stock. when I keep the voltage to auto in bios, it reads 1.5 in bios and 1.46 in cpu-z and hwmonitor. When i set it to Manual and Normal (reports normal as 1.375). It shows 1.42 in bios, yet cpu-z and hwmonitor both report 1.375 . Which one should I trust? And why would the bios automatically over-volt the cpu like that? I've had it stable at 4.0ghz on the normal setting (so it's not like it needs that extra voltage @ stock).

I would think the bios would be the accurate measurement but why is it reading 1.42 when i specifically set it to 1.375 ? BIOS is latest version.

Auto or default is a starting point, it's best not using auto settings when overclocking.
1.4v is the maximum safe vcore for 965be 125w(1.5v will hurt the chip).
Try to set 1.375 without overclocking CPU then see the BIOS readings.

It's normal for the BIOS to read a different voltage to Windows.

I have to undervolt mine in the BIOS as Windows reads a higher Voltage.
