Which Voltage is correct?

post #1 of 8
Thread Starter 
i have changed the voltage of my cpu to 1.28v in bios but in cpu z it says it is 1.248v and everest says 1.25v...
which is the actual voltage 1.28v or 1.25v?
i have a i7 920 at 3.67Ghz stable at "1.28v/1.25v" is that too high for a 24/7 oc?
thx for reading any response is greatly appreciated.

Your motherboard is vdrooping your voltage while Idle. Cpuz and Everest are both correct at thier respective readings of your voltage.

If you have LLC enabled in your bios, then you'll get the full 1.28v while on cpu load.

Exactly. 1.28v is the voltage you'll have under load, and it may even be slightly higher if you have the setting enabled that gives it a little overhead room (most people have this set to 100% - it won't go higher, or 110% - the BIOS has the ability to automatically increase Vcore by up to 10% should the CPU need it). The lower Vcore you're seeing in those programs are the BIOS clocking down the CPU when it isn't under load. Since it's not running at your OC'ed frequency, it doesn't need as high a Vcore.

even when my cpu isnt idling it doesnt run at 1.28v. for instance if i am playing bfbc2 it does not change. I havent tried prime 95 yet cause im too lazy to set my fan speeds and then back again with the stupid knobs that the frio has.

Enable LLC( Load Line Calibration )

It will help give you 1.28v when you are on cpu load.

LLC is set at auto, and if its stable at 1.25 why would i want to disable it an run at a higher voltage?
