Why is my vcore fluctuating?

post #1 of 9
Thread Starter 
Well, i have LLC on, and have my mobo at a set voltage, but it appears to be giving more than i tell it to give? Is this normal under CPU-Z

Is it fluctuating constantly between different voltages? If it is at a constant, then you don't have to worry. I have set my vcore to 1.325v in my BIOS, but CPU-z reports 1.328v. If you only have a small difference like me, then you don't have to worry.

in the BIOS it is set to 1.243 (or something near that), but under load like Prime 95 it goes higher to things like 1.256V
Maybe i should shut down LLC ?

That is just the way LLC is on some boards. Voltage rises under load. I don't like it (rising) so I don't use it on my P55 board.

often LLc helps you get a higher clock on lower voltages, but that sounds more like a "cool and quiet" option to me. it makes your voltage go down so it makes the card run cooler when you don't need it

Nah I'd say thats LLC working.

But he has Intel, so speedstep.. and I doubt its that.

I forgot to mention ALL power saving things are disabled
such as speedstep (also turboboost), C1E, and C-States

So is this normal?

Yes, it's normal. LLC is compensating for the vdroop on load.
