Vcore set to 1.5V, but goes over that!

post #1 of 35
Thread Starter 
Hi.

In my attempts to overclock I have set my Vcore to 1.5v in BIOS.

In idle it is at 1.5Vcore, just what I entered in BIOS.

However, when I stress test my CPU with example OCCT, my Vcore jump to 1.58 :S

It freaked me out when I noticed this. Why is it doing this? Is it supposed to do like this or is it some strange setting? It doesnt soon too healthy to jump up to 1.58Vcore.


Thanks in advance.

variations on Vcore are somewhat normal, but it shouldn't be that high. Did you already disabled Cool n' quiet/PowerNow, whatever your board says that enables CPU throttling?

Yea but almost 0.1v is pretty much I assume.

I did disable Cool'n'Quiet, but I have no idea what C1E is, which I left at auto. Should that one be disable too. Can C1E be causing it?

Im too afraid to test again lol

turn off "No Vdroop" and it should go down instead of up when under load

C1E and EIST are technologies that enable CPU throttling, meaning that they will reduce voltage and multiplier for power saving and less heat.

What are your BIOS options on the CPU panel?

Okay, in my case something makes the opposite, raising the Vcore.


I don't quiet understand your question, but do you mean the settings for my CPU in BIOS?

In that case, I tried with the following:

CPU Multiplier: 13.5
FSB: 300
Vcore: 1.5v

I'm not quite sure about what is raising your voltage that much, but i'm guessing that might be a BIOS setting somewhere for the stability sake, that might no working properly.

I meant what options you have in BIOS on the CPU configuration, where you also have C1E and Cool n' quiet, virtualization, etc. i had a similar board to test a few weeks ago but i can't remember now...
Do you have any Turbo mode setting enabled on the BIOS? any board option to tune itself? or the CPU's own turbo funcionality?

Load Line Calibration (LLC) is what's causing it. Either disable it, or reduce the amount of voltage it's set on.
