ok im fairly new to the 7850 I got it and have major coil whine so I dropped the High performance GPU clock settings clear to 370mhz and put the High performance memory clock settings to 1450mhz and there is no coil whine at all but I kinda think the games are alittle laggy I might be looking to hard can someone explain to me if this was a good idea? or should I send the card back and try to get one that might not have coil whine? thanks ahead for any help

I don't think that you will get another faulty one, I have a XFX 7970 and performs beautifully, runs every game on High and only has a weird sound coming from the fan when it is overheating and stuff. But if you turn it up to high then it is pretty much silent(I cant hear it over the gunfire from BF4).

That sometimes happens with XFX cards. It isn't a huge problem, just go into your GPU settings and set fan speed to 'HIGH'. You could be able to do this in your BIOS or in the Overclocking software you should have. After you have put the XFX fans to the highest settings there shouldn't be a noise, I have a XFX 7970 and that's what I did and it shut that graphics card up. If this doesn't work then there is a problem with your fans. Send them back to get a full refund (only if turning the fans on HIGH doesn't work).

Then send it back for a full refund. That's what I would advise because that situation doesn't sound good.

Have you tried turning up all of the fans BEFORE you reset all of your clock and memory clock settings?

You should be able to increase the voltages with your GPU Overclocking software. All you do is just slowly increase the voltages. But i'm almost definitely sure that increasing the voltages will not help that noise. Take my advice and send it back to get a full refund.

Dropping the GPU clock just makes the whole card a lot slower. It's like having an i7 3770k @3.5GHz and underclocking it to 2GHz.

As I said before, I strongly advise just sending it back. Get your money back or get a replacement 7850. XFX as a GPU manufacturing brand aren't bad its only some of there GPU's occasionally are faulty.
