I'm getting the dreaded coil whine issue with my new 960 ssc, but only very specific settings. It does it for 3dmark ice storm benchmark, and the stalker call of pripyat main menu sceen, and binding of isaac, but hasn't done it elsewhere. I have only had it running for all of 4 hrs so obviously haven't put it through the full ringer yet. What do you guys think, is this a sign of things to come, or could there be something specific happening to it?

Seems that Maxwell has a higher percentage of this issue than Kepler ever did. Usually coil whine will dissipate over time with use, even most report reduced issue after a burn in, but this is in general and not validated with Maxwell as of yet to my knowledge.

I once speculated the higher issue rate with this is partly due to the varying voltage modulation used to reduce power usage in Maxwell. Same is seen in Automobile computers for fan switches when a frequency is used to turn on the relay, it hums loudly during certain frequencies.

To get rid of coil whine:

1) Run with adaptive vsync on (Nvidia driver control panel, 3D settings section, down at the bottom. This will limit your cards to only output enough FPS to equal the refresh rate on your monitor. (which is the max you can see anyway). 60hz monitor, max you'll ever see out of it is 60 literal fps. 120hz monitor, 120fps max. So limit it to this and various menus and game cutscenes won't fly your FPS up into the hundreds causing this.

also, you can

2) Get Nvidia Inspector and limit your FPS to 60hz with this. It's in the settings section, believe it looks like a "wrench" icon inside the app

Coil whine is caused by a sound resonance that is reached inside certain electrical components (namely inductors) when you reach a certain high FPS threshhold (hundreds or thousands of FPS. If you have a 60hz monitor, doesn't matter if you can put out 300fps, you won't ever see anymore than 60fps out of your monitor.

So just limit your fps to 60 with either of these methods and coil whine should go away

This is out of topic here.. nothing to do with the OP..

this is the reason of the OP coil whine, that type of coil whine its absolutely and completely normal with ANY card in the market no matter brand AMD or NVIDIA, not matter model, all cards can and will coil whine at high amounts of FPS.. (generally 1000+FPS as mentioned by Ultranifty)..

Wrong not off topic and greatly relevant. Rather than pretend to be superior, how about comment on my points or not quote and refrain from comment all together.

really 60? everyone knows the eye can't see more than 24fps.
:D

actually in fps games 300fps is easily noticeably better than 60fps on a 60hz monitor

again that post its off topic and nothing relevant.. percentage of coil whine maxwell vs kepler? really? how that help in this topic?. also coil whine does not "dissipate" over time as its basically hmm, lets say produced by "vibrations" if you understand what really is.. but also a "burn in" doesn't help with coil whine or with the OP "issue" but also, the coil whine have nothing to do with the "varying voltage modulation used to reduce power usage in Maxwell" as its well known that coil whine is brand Agnostic and Architecture Agnostic, so it happen with Maxwell, Kepler, Fermi, Tesla G80 and so on so your "speculation" about "varying voltage modulation used to reduce power usage in Maxwell" its fail and can be misinterpreted by the users and what can happen? a new rumor "I read in a forum a guy who said that the adaptive voltage used in Maxwell cause coil whine, crap Nvidia and the Fail Maxwell Architecture" (without even mention that the same adaptive voltage/clock frequency/TDP method its used in kepler)..

same apply to AMD cards.. all will have that crying dolphin called coil whine at ultra high FPS(those mentioned by the OP BTW, Main Menu Screens, 3dMark IceStorm, Intro cinematics, etc etc) but also isn't a specific GPU issue as also happens with PSUs even if are top-end or crap PSU.. what can you say about PSU coil whine? are kepler or maxwell included in PSU coil whine?.. :p

so what part in your post its actually accurate enough to be on topic? just the last part "during certain frequencies".. you could start explaining to the OP what coil whine is (like Ultranifty did) and how to avoid in his case (again as Ultranifty did) and done all solved (with the exception of the troll rabidz7 hanging around out of his cave)

Wrong again. Nvidia uses a new Voltage modulation akin to What AMD used in CPUs, a kind of recycling of the unused voltage, easily seen with an oscilloscope. Also I didn't attribute all coil whine to this just that the higher percentage complaints, again easily seen, could be due to this as a possibility. But again I did not assert that this voltage modulation was definitely a cause, rather speculated on it for future debate. I was basing the possibility on HARD PROOF of the same thing happening in automobile computers using the EXACT same concept and components I see at work.

So if wish to debate this phenomenon based on my speculation in a mature and respectful, then I am willing to do so. If not, well (insert any profane comment here).

And by the by I also Never mentioned AMD nor was making this a war of color, you did that on your own. So it goes without saying you are the green team pocket buddy.

how about we cut back on the insults and off topic crap and try and help the OP?

^^^Haha my problem was solved with the second post, i just stepped back so I wouldn't get caught in all the crossfire.
