What is my correct vcore?

Heya =)
I dont know what my correct vcore is... i dunno what to trust :/
If i set it at 1.475 @ bios then bios tells me in "pc health" that its @ 1.44
If i then check in Cpu-z , Everest or whatever it says 1.42
What is my correct damn vcore? :S
:confused:

EDIT : This is my system
DFi lanparty nf4 ultra-d
Amd x2 3800+ @ 2.4Ghz
corsair xms 2048C2
gainward 7800Gt

Welcome to XS !! :toast:

The BIOS reading is closer to being correct and may even be close to right, there is no way to know for sure short of testing with a DMM.

If you set it in bios to 1.475v, it's very likely to be very close to 1.475v :)

Break out the multi-meter! Only way to know for sure, my DFI reads under, not by much, but definatly under. 1.475 bios is more like 1.5v real *on my DFI*.

Yea... but its a pretty big difference for me since i just got some aircoolin (tt big typhoon) 1.475 - 1.42 hmm, but the main thing is ... i wanna know if its over or undervolting?

yup i have same problem with my dfi ultra-d does the new expert series do this? i can set my v-core to 1.5v in my bios and when in windows it reads 1.456v in cpu-z so im not sure what to believe either? now isnt there a way to messure it with a volt meter? i have a volt meter if anyone knows the correct contact points on the mb.... maybe the other poster may want to take note too just incase he has a volt meter too...

Theres your point, its a resistor at the side of the socket.

You have an old style analogue meter or what? Its just that most people just have DMMs, not 'volt meters'.

My dfi under reads both vcore and vdimm, so heres the check point (well you may as well have a look at it if your proding things with you meter)

I also attached the check point for VTT so you can have a look at the stupid amount of fluctuation during memory stress, and join me in trying to FIND WHERE EMC2 (and his corrector circuit) HAS GONE!
