To be fair, Nvidia did say they could use the 670/760 PCB's if they wished as GM204 was fully compatible. I do however believe the final choice was made by the AIB's and as such are to blame, not Nvidia for this.

Does not go away for a lot of people,PSU seems to make a difference however in a few cases,thread over at OCUK forums http://forums.overclockers.co.uk/showthread.php?t=18630402 quite a few have coil whine.
I wonder how it got through testing?
Btw this post was interesting over at OCUK,from page 2 of link above.
Changed the spec on my own build 970 reference NVIDIA card:-
Hi there
Good news regarding coil whine, we've requested our factory to make some changes to the capacitors on our cards, the revisions include:-
Capacitors surrounded by plastic containers which are then stuck to the PCB by glue, very similar/same to what Powercolor themselves do on PCS+ cards. This will help reduce coil whine and eliminate it. This has cost us extra but we won't be moving our retail price on this model.
A photo of the capacitor in the container:
As the OcUK 970 is a design/build request by myself I have influence over the parts used and my original specification was NVIDIA BGA + Samsung memory, so built to NVIDIA standard using only NVIDIA approved components, so the quality was already high. We've just now implemented everything we can to help reduce/eliminate coil/whine into the design.

Who cares about coil whine anyway?
90% of the cards I get have coil whine. (I call it the sound of performance). I think it's both the fault of the AIBs and Nvidia. They should put some standards about the capacitors and such part that can be cheaped-out.
( I don't understand why he needs to bash AMD and defend Nvidia...always ...always... and now on two different forums. )

I dont think you understand how loud it is on some people's cards. surely its not hard to figure out that its at very annoying levels for some people so that is why its become more of a news story.Who cares about coil whine anyway?

some people have posted vids and yes its crazy loud in some cases. plus its the type of noise that can make you cringe. and there are just craploads of complaints about this.

I have never had coil whine on any of the cards I've had from either Nvidia or AMD over the decades since Voodoo 1 days ,if I did it would go back.
There are plenty of threads on 970 coil whine issue ,quite a few very loud.

I had a 7970 reference that had terrible bzzzzbzzzz coil whine, could not stand it. I also had a reference 670 that had the same problem, even louder. Could not stand that.
I noticed in the reference R290/X design (re-used by a few AIBs), they marketed it as having better capacitors & ceramic chokes to reduce the prevalence of coil whine. Luckily, both my R290 have no coil whine at all. It's great.
The noise isn't as loud as the AMD ref blower, but the pitch and sound is very annoying. Like a swarm of mosquitos..

Sharp with what? Probably doesn't know a thing about electronics, is socially talented, and is experienced in marketing/CS. Should have run it by others before posting it.

Meanwhile, someone who does I'm sure has properly communicated that they need to glue or lacquer inductors.self said:

Hopefully Nvidia and AIB fix this as 970 is an excellent card. Never had a terribad card regarding coil whine but i've seen some friends going crazy over it.
yes and coil whine is far more annoying than any fan noise (at least for me); if these VGAs were extremely cheap maybe it would be fine, but for an $300+ product to have problems like this is pretty bad... but as I said before, to a lesser extent most cards seems to have issues with it

I'm no electronics expert however it's nice OcUK are doing something about it rather then ignoring the issue like so many others I could mention,Gibbo was the one that posted that statement is an active OcUK staff member in the forums and always trys to help people out.
End of the day I think we can all agree there is an issue somewhere and something has to be done to correct it.

Usually, most samples of a specific model will have it bad, if any. For example, that cheap MSI R9 290 is known for having it bad, along with many of the R9 290X models, some 780 Tis, and some 670s.
With the R9 290, as an example, you could get a PowerColor PCS+, a Sapphire Tri-X or Asus DirectCU, and be all but guaranteed it won't have any* (and, they'll generally honor an RMA over the issue, since that is one of the reasons for buying said model, and such an RMA replacement generally will lack it).
This is occurring with all brands of 970s, and most brands of 980s, and is not common to certain models (but, much more common on the 970s, it seems, by quite a bit). Asus and EVGA, if not others, do consider it a sufficient flaw for replacement, from what I've seen (mine's going back as a plain refund return on Monday, and this will be only the second video card I've ever returned, and the only one that functioned as advertised).
In some cases, a PSU swap fixes it. That doesn't mean the PSU is at fault, unless it's straining under the load (and the PSUs I've read about being swapped should not be!), because the same sort and degree of current and voltage fluctuations should be happening on Haswell-equipped motherboards, especially the new X99, and should cause similar issues. Instead, most motherboards have been mechanically inaudible for a decade or more, now, even many big vendor ones with bare chokes (Dell and Lenovo, at least, still use unpotted ones, and they are quiet as can be...they also have many times the diameter of copper per winding).
* Of course, this is isn't an issue of absolutes. Not having coil whine means someone sensitive to such noises doesn't hear any from a few feet away from the closed case. Same as, "silent," really meaning, "inaudible, when installed."

Cerb I'm sure your right and Gigabyte may have done it already. I got the Rev 1.1 and have no problems at all... if I did I was just going to order some inductors and replace them at work on my own.
Mem sorry if I came off as an *ss but some of the information Gibbo was posting in that one thread (only one I have ever read from that forum) was just plain off the wall. Like Cerb pointed out there was a lot of talk about bad power supplies in that thread that were just wrong and suggesting people replace a $100+ dollar item over bad/cheap inductors rubbed me the wrong way.
Just my 2 cents.
I just wonder what was changed from rev 1 to 1.1 on the Gigabyte gaming and if this has been an ongoing problem the venders, all of them should have been on top of this before the boards were released.

No problem,I'm using AMD 280X so not bothered by whine issue,however still nice that somebody is doing something about it.
Btw pic and quick specs of whine fixed OcUK card, stock due on 7th Nov.

Because you use a 280X doesnt mean you cant have coil whine.

Unfortunately its something we had since as long as I can remember.
