Yes, under Spy Time has way less whine.

Coil whine is a luck of the draw. All electronic devices will suffer from it in certain degrees of severity. If it really bothers you then best you can do is return the card.

Yes that happends because with Valley you have less vdrop at the same frequency of work - For example 1266 mhz but 1.120v when you run tests like Time Spy, or Firestrike your power draw probably will be the same but the vdrop will be more massive for example 1266 mhz and 1.113v so the coil noise it's less - In practice you will not make that type of "stress" in normal gaming - So it's nothing to worry about.-

For example in Valley when you cancel and you are in the "credits" screen your coil will be talking to you rolleyes.gif

It does that in heaven also, I had coil whine with my Gaming X card and it drove me crazy so I replaced it and the replacement still had it and while its bad its still not as bad as the previous one, luck of the draw man luck of the draw.

By the way I have solved the black screen issue after turn off the xbox app dvr. If you need to solve it, ask me.
post #2916 of 4152
I think I may have fixed it! I undervolted the memory keeping it on 2000mhz. Now I can hear mostly fans and also little bit coil whines. I'm gonna test more.

I would probably return it as defective. One of the chokes was likely not fully back filled or immobilized internally, causing it to vibrate under load (they generate pulsed magnetic fields that can cause them to vibrate). The old fix for this was to use clear nail polish on exposed coils, cant really do that on sealed coils.

You think so? I kinda don't like the hassels of returning it to Amazon (I've never done it!), but maybe I should!
As this card is OC+ version it seems sapphire has pushed the limit with it really badly so undervolting while keeping the same clocks, specially reducing memory voltage seems to reduced coil whining a lot I have to put my ears next to card to be able to hear it

Well the OC Version probably have that type of things, but if you undervolt the memory and the coil noise it's reduced no problem! - Use HWinfo to check if you have "Memory Errors" in the GPU if you don't have it - just left that voltage - Don't know if the OC+ have more freq of memory, I have the mems in 2160 without changing the voltage so, probably don't need a lot of voltage to be stable.-

----

By the way - Somebody test this type of "Silent Fan rubber" ? - I have a few nice Fan to put in the AIO water of the RX480s the problem it's they vibrate in the radiator and sound like the hell - I don't want to buy new fans just for that, and see this cheap and stetic rubber to put - But... don't know if really do something or it's a waste of time.-

Agreed with you on the RAM speed - if he can adjust the voltage down to get rid of the noise without losing performance or having errors, then it's problem solved.

Also, I have used similar products in the past to improve the sealing surface between my fans and radiators to great effect in regards to both noise and performance, so I'd say +1 on your idea of using it (better than the rubber washers I used before that).
