EVGA 760 Coil whine

Hey all, In my recently built rig ( 1 week ago) I have noticed my EVGA 760 ACX Super-clocked has very noticeable coil whine. I have tried to change voltages slightly but that seems to be impossible as the card looks to be voltage locked from what I can tell.

(Forgot to say I have an XFX Core edition 550w PSU if that helps)

Any potential solution suggestions would be appreciated, thanks ;)

Im probably not the best person to help as I've not experienced coil whine however I might be able to help with changing the voltage through EVGA Precision X.

I was able to under-volt my GTX 570 using the normal voltage control successfully but the settings wouldn't persist after restarting and re-launching Precision X. I can understand voltage limits as the 760 ACX is based on a ref PCB but being EVGA I would be surprised if it was voltage locked.

Hopefully with some tweaking you might be able to reduce some of the coil whine. The advantage with EVGA is that they are usually helpful with issues of this kind. I would head over to their forums and describe the issue there if you haven't already done so.

Another option is to cap the frame rate to the refresh rate of the monitor reducing the load on the GPU which should reduce coil whine.

Hopefully someone could give some insight on your PSU, that might in part be causing some of the issues. 550w should be enough for a single 760 though.

Thanks for the reply, Ive tried lots of GPU overclocking programs but the only Voltage change i could manage was + 12mv in Precision X which was the only increment possible to make up or down and that made no difference. Vsync does help but i don't really want to be capping frame rates plus I only know how to do it constantly and not just in games.

Thanks for the suggestion though, I think i will try the EVGA forums. Cheers man.
 
I use MSI afterburner to remove their built in overclock from my gtx570, kept getting opengl driver lost connection errors.
 
Yeah, In afterburner the voltage appears to be completely locked :( But with all these programs i may be missing some secret to getting them to work..
 
I had coil whine with my GTX670 when I first bought it, I was a bit miffed as I had spent a small fortune in a full watercooling loop and the noise spoiled the experience. In the end I fixed it by running the Haven benchmark in a constant loop for hours (run it over night) on end which fixed the issue for me.
 
My EVGA 670 FTW 2 has coil whine at times. When a webpage with little on it is open full screen in Chrome, or on game menus with vsync switched off.

I think basically when drawing loads of frames. Slightly annoying but in audble over headphones/speakers.

As Stratosphere said, if you cap the frames it should go away.
