I mean its fairly noticeable if I put my ear to it! And very noticeable if I open the side window and try to hear it!

EDIT: Searching on the topic a bit made me realize I am gonna stick with my card! Don't have time for this and also I need my rebate! The card works fine, the whine is not that bad, and I wear headphones!

It was a huge issue with the gtx480s people were going as far as coating their cards coils with fingernail polish. If you just got it you might be able to rma it with who you bought it from, but I wouldn't RMA with the manufacturer. If it's solid and it overclocks well, like you said you have headphones haha.
I finally got my voltages to stay solid, I tried disabling ulps and disabling powerplay but never both at the same time.

Same settings as in the first post but with ulps disabled and powerplay disabled. Seems more solid but nothing special, the small gains and still not hitting that score on 3dmark11 I got earlier. Musta been a fluke.

I don't think they have to be UEFI themselves, just need to be capable of supporting it.

Latest asus rampage III extreme is 2011 Oct frown.gif
No new updates after that. Anyway, can I crossfire with 850 watts PSU?

I got an Asus P5Q-e. The last update for it was around 2009. 7870 MYST works fine on my system.

I did a five run comparison in Heaven with/without powerplay. In every case, fps and total score were more significant; 20 ftps in one case. Minimum fps was also a lot better too. Powerplay activated WON everytime.

Try an experiment with 3dmark11 and compare the difference. After several runs, I would love to see your findings. My current theory is that AMD tuned these chips to be performance optimized with Powerplay enabled. But this is only a theory at this point.

I had the opposite experience. With powerplay off, I got higher scores and more FPS. 3D Mark was about 8800 with powerplay and about 9300 with powerplay off.

My friend has the 660 ti. I think that overclocked they both perform pretty similarly. Funny because I'm usually the nVidia guy and he loves AMD. Stock the 660 ti definitely edges the 7870 le but you'd be a fool to leave it at stock. Either of them. The 660ti has less micro-stutter but larger frame drops if that makes sense and their drivers are decent. Not as good as people will make it seem. The 660ti has some z-fighting issues as well and I've noticed this on even the 7870 LE. Basically, pick which ever one is cheaper.

A 660 Ti is never cheaper than $270 w/out rebates. That's why this card is such a great deal.

I heard coil whine dies out with time. It won't damage your card b/c pretty much everyone has it.

HD7870 LE card is a better performing card and for the money its a much better value.

The only real PRO about the 660ti is that it comes in smaller PCB sizes which may come in handy in a small case. The HD7870 LE card is huge. Between 11-12" long with the heat sink on it.

Same.. I also played FC3 with powerplay off it cut FPS in half.

I'm diggin' these cards for the price but I'm about ready to start bios flashin' and I've only had them since Thursday, I just realized they're down clocking to 925 when I push them to near 100% no matter the temp.
Some games they also like to drop gpu usage randomly when you push them, at least that's what I was noticing in Spec Ops: The Line the other day which I think is what causes it to shutter every now and again in the game.

They're the .028 bios if you wondered.

I got my powercolor MYST CF today and I too having same issue. It downclocks to 925mhz very often.
I tested with default settings first. After that, I OC'ed to 1100mhz and didn't downclock to 925mhz.
Btw, how do you check which bios you have?

GPU-Z and try flashing your BIOS to .28
