Gigabyte 970a-ud3 keeps changing my voltage

Zkirtaem · Jul 17, 2014

Hello! I bought lately this 970a-ud3 and fx-8320 and i have a big problem. Namely, my voltage is changing on load - and i've turned off everything i thought that may cause it in bios. I don't complain at first change ilde/load - after overclocking to 4ghz and setting voltage on lowest possible (hwmonitor was showing 1.3v ilde and 1.36v on load) first 20 minutes of prime95 was flawless, but then suddenly (prime95 still didn't reported a single error) voltage jumped up to over 1.4v. Of course my kinda cheap cooler couldn't handle it and temperatures rose to 65C, i had to end it.

What can cause it? Maybe i missed some important setting in bios? Or is that normal - modern method of ensuring stability or something?

Load Line Calibration or LLC. Set it to MANUAL and the 2nd highest setting. That usually is the one that will keep the voltage under load close to what you set it at in the BIOS. The highest level can on some motherboards but usually itll raise the voltage under load too.

Unfortunately i have only "regular", "extreme" and "auto" in my bios under LLC setting.

Try them both and then run something like OCCT and watch the voltage. Extreme will probably be the one that works best but try them both to be sure.

Thanks, i think problem is solved: i installed different BIOS version (i had some kind of beta earlier).

But one more question: Where, except "cpu voltage", should i search for things that can decrease voltage? I can't go anywhere under 1.36v with this setting and i have stable 4ghz here so i think i should lower my voltage even more, especially since i have kinda crappy cooler.

Zkirtaem :

Sorry to bring up an old topic, but I'm having the same kind of problems with my Gigabyte 970a-ud3p board and fx-6300 cpu as well and was wondering if you could confirm if your problem with it has been solved.

No matter what I set the voltage to in the bios the board keeps lowering it on me under load. The last setting I remember trying was 1.43v at 4.5ghz, but the board wouldn't put the vcore above 1.40v or so under load, and it frequently dropped down towards 1.37v, which was killing performance compared to the 4.4ghz with auto voltage (seems to range anywhere from 1.38v to 1.402v) which is the only way I can keep it stable.

Keep in mind I had this chip stable at 1.44v at 4.6ghz on a different board, but I decided to upgrade to this one because the old board had a crappy power phase and kept overheating it's vrms and would eventually downclock the cpu.

I've tried disabling coll n quiet, enabling hpc, and all the usual stuff, but it doesn't make a difference. I'm going to give the LLC a shot as well as checking for bios updates.
