Hello sifus, still a beginner at OC, I have some question regarding my OC i5 2500k @ 4.5Ghz.

Using MSI P67A-GD65, I set 1.3V Vcore at the bios, and the bottom shows that it is running at 1.28v. However once boot into the Windows, CPUZ show me Core VID of 1.376v, but AIDA CPUID do show the same 1.28v.

During prime95, CPUz shows 1.381v and AIDA shows 1.271v.

Which value show i trust?

CPU-Z or CoreTemp? CPU-Z will show vCore, not VID.
VID is different from vCore. VID, is essentially the amount of power required to get it going. Vcore is the voltage that the CPU is running at.
What's your vdroop control set in BIOS? FYI, vCore set in BIOS will not be the same as those readings on CPU-Z & AIDA due to vdroop/vdrop. You might wanna google for more infos on that.
Some screenshots might help on your problem.

My Vdroop in bios is high. I will be using AIDA CPUz as my references now since I changed the cpuz.ini to display VID.

Been increase my Core voltage in bios from 1.3 to 1.325 currently. Still finding a stable voltage for my 4.5Ghz.
Do I have to worry about VID readings too in my OC ? Or I can just ignore it and only pay attention to the Vcore and temperature?

Is my temperature doing fine ? I do suspect that my heatsink is not installed so probably and thus result a high temperature.

Be sure in cpuz.ini file Sensor=1.......Core Voltage.
Sensor=0.........Core VID.

To be sure run this portable CPU-Z :

I think i know the problem. Since my CPUz cannot be run together with AIDA, I did changed the sensor=0 in cpuz.ini. And thats why i mixed up with the default Core voltage reading.

Why AIDA64 and CPU-Z cann't run together?  hmm.gif
No conflict beetwen any of monitoring software,only AISuite with some.

I have absolutely no idea lol. But I did google up similar problem and it did solved my the problem.

I'd pay attention on the vCore, since it's used in the BIOS.
VID is useful for chip binning. smile.gif
Your temps look fine.

Okie. I will be ignore VID for now.

How about Vdrop high vs low ? Which is a better option to choose from ?
