LOL. My board is worse. I have a + or - range of .09 in both directions because of LLC.

Placing LLC on "Normal" reduced the overvolt for me. now it's set at 1.5000V and cpu-z shows 1.534V

I have the same thing with mine. My actual vcore is always .5v higher than what I set it to in the bios (no stepppings enabled). I actually started a thread about it to get an answer. Never did, I just remember the variable and set the vcore accordingly.
post #25 of 35
op...leave it alone and start with the lowest voltage till its stable. is nice option becuase you get to idle low on voltage and when you need the power...it will raise it automatically. for example...lower your cpu voltage to 1.45volts and on full load..you should see 1.5volts then. its a good feature on most board. my msi did it also. it adds .03volts and my crosshair 4 gives it .05 volts on load.

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.
bad overclock

You may not be that stucked. If you can't disable LLC set the voltage the 0.08V lower in BIOS, so at full load it will go to 1.5V. In idle you must get stability with the lower voltage, but if not you may need to go a little past 1.5V...

Nikkopo. I think I just tamed my Vcore spike down considerably. Mine used to jump from 1.46 to 1.51 under load. Now I'm idling at 1.47 and going to up 1.49 under load. A little easier to manage temps. What I did is dropped my VDDA voltage from auto, which set it at 2.39V, all the way down to 2.2V You need to have an idea of what voltage your CPU needs to be stable at your given freq. I know, for 4.0Ghz, my CPU needs at least 1.48V to be happy.

So I raised my Vcore about .02V more, and dropped my VDDA voltage to minimum. The .02 raise in Vcore accounted for the .02 less in spike. I think I'm more stable now as well. I the idle at 1.46 was causing a couple of my random BSOD's every once in awhile.

Thanks for all answers.


I asked Gigabyte about LLC and got this answer:

"Hi Nikko,

LLC is a Intel feature. AMD motherboards dont offer this. The similar feature is AMD Cool & Quiet, and can be compared to the Intels C-states and C1E.

I guess your problem is anywhere else, maybe incompatible memory or a unstabile PSU.

Best regards
GIGABYTE-team Scandinavia
