Coil Whine, need help!

post #1 of 9
Thread Starter 
My 7970Ghz edition just randomly decided to start giving me coil whine couple days ago and today went to play Witcher 2 and it got so bad that i had to stop playing. It varies in intensity but it is most noticeable while playing more graphicly intense games. I heard that over-volting the card may decrease or eliminate coil whine and i was wondering under what safe voltages the card will operate at, and if the xfx is even unlocked...

Also i tried RMAing it and they will not accept because it does not harm the performance of the card.

Normally i would just play through the pain but it gets so high pitched while playing Witcher that it drives me crazy...

I've never tried this myself, but in another thread someone recommended to just let the card squeal continuously for about 2 days (loop a benchmark or something similar), and then the capacitors will have settled in and you won't have coil whine anymore.

Is your VSync ON or OFF?.. try it with ON

It will probably scale with your FPS, so like said above, if you can cap it with vsync it should quiet down. Other than that, are you %100 sure its not a fan? They can sound like coil whine sometimes, stop each one separately when the sound starts and see if that stops it. Last thing you can do is try putting some nail polish on the noisy cap, to get an idea where it is, you may be able to compress the cooler against the card in different areas while it is whining, when it stops, you know you are pushing in the area of the noisy cap.

I am sure, I can change the intensity of the whine by looking in a different direction in game. i.e. looking at a dense forest with intense lighting it is loud then looking to at a solid color like the sky or a wall it quiets down.

This is because the framerate is changing. Cap the frames at 60 thru vsync in the drivers or thru software.

And read the post from above.
