GTX 1080 undervolting and underclocking?

[ramo55]

So I've got a few questions since I can't seem to find much related to this card online in terms of undervolting and what not. My gtx 1080 has the dreaded coil whine. It crossed my mind to try undervolting the card so it requires less power which would reduce the intensity of the coil whine that I can hear. I downloaded afterburner and I set the voltage to 800mv, with a frequency of 1700MHZ at that voltage. The card performs well, and doesn't increase in temp above 56c. Does that mean I've undervolted it? The coil whine has gone down, but I'm worried in case I've limited the performane of the card and not atually just undervolted it? Any ideas? I can post my graph in after burner if needed

Really I would have no clue how to fix what you mentioned above but I'd say if you have the original issue sorted that being the coil whine dying down I'd say your on the right track and good to go I hope you get it sorted no matter the case

Well I want to fix the coil whine issue but I don't want to limit the performance of the card, hence why I chose undervolting so that I can lower the power without lowering the performance. The issue right now is I don't know if I've reduced the performane of the card or not. Why do people undervolt at 800mv and not more or less?

I couldn't tell you lad best way to figure out if it affects performance or not is to reset it to default benchmark it and then apply the same settings that you have now and benchmark it again to see if there Is a performance difference

Well read what the voltage runs at when you benchmark it.

Then lower the power or voltage and see where it runs at with the same benchmark. 

Would tell you if the undervolt actually worked.

Better way to undervolt is to set a lower power target (of any % you want), then raise the memory clock offset (first) and core clock offset (second) while validating for stability as usual
