BIOS voltage vs CPU-z

[gamerdude1989]

hi guys

why is the BIOS voltage different to whats shown on CPU-Z?

i am overclocking a friends Core 2 quad q6600 for him, and can get 3ghz from stock voltage, but am currently trying to get 3.2ghz stable, on AUTO voltage, CPU-Z states that the CPU is pulling 1.34v under load, So i set the BIOS voltage to 1.34500 and its not stable under load at all!

i have been on manual voltage until now, as i wanted to see if perhaps 3.2ghz was just it for the chip, so quickly set it to AUTO voltage to do a stability test, and yep, on AUTO, its stable..
But find im having to really bump up the voltage in BIOS to get 3.2ghz stable..

Currently upto 1.38v and still not stable under load...
But according to CPU-Z, on AUTO voltage, 1.34v is the cpu's load..

ive even tried bumping up the FSB and RAM voltages by 0.1v too, to see if its that, thats causing the instability so far into the overclock.. but nope..

cheers

You sure CPUZ isn't showing VID volts instead of VCore?

DL Hwinfo, sensors only and have a look at the VCore high reading on auto.

My vcore on hw monitor sometimes shows over 1.5 vcore. Never seen this while it's using that just noticed it at end of my session as the max. I did notice it had a max of over 2.0 vcore after I made a change in bios nothing close to that. Something like 1.25. After this I reverted it back to defaults. But still sometimes shows over 1.5. No idea why.
