i doubt its dropping while you are playing games.
I dont have BF4, but I just tested on Project Cars and Dirt Rally. It is steady at 1100 at the beginning, FPS is lovely. Actually I got like 20 fps increase from stock clock, but the core speed drops to around 900 then to 800, 400 and then again up to 1100 and so on. FPS also drops.

I found a "solution" to my issue. It is such a pain to switch between the profiles all the time. Any way to make it auto?

Hi i have a PowerColor 7870 Myst Edition. A while ago i had a 85C temp on it. So i decided to buy an aftermarket cooler. What would be the best aftermarket cooler for this GPU? People are saying that i should get a nzxt G10 but I don't know if it would fit. Someone has a guide here or something with the same GPU as mine? Thanks!

Same card here, and recently I've installed an Accelero Twin Turbo II. It's easy to install and keeps the card cool. GPU temperature is around 65C, vrms around 70-75C under load (1100/1500, 1137mV).

Hi was it all worth it? The only cooler available in my place is Gelid Icy Vision :/. I got a 85c full load a while ago while playing dota2 on high settings.

Definitely worth it. Finally I don't have to worry about temperatures and this cooler is damn quiet.

You may backup your bios with GPUZ, mod it with ATI_VBE7.0.0.7b so that your settings be 1100/1500 in both normal and Turbo (no more fluctuation), then flash your new bios with ATIWinflash.
All instructions and setups are available on the first page.

BUT, to do that you must first be sure that your temps are safe in benchmark tools like Unigine and 3D mark,
as the others, I recommend you to uninstall Furmark, as this tool is definitely not representative of the real world, and potentially damaging your card.

I just sold my PowerColor 7870 Myst Edition for 75 Euros...feels like the end of an era for me, 2.5 years. sad-smiley-002.gif
Now I'm waiting for the R9 300 series to arrive, hopefully there will also be a price/performance bomb like the 7870xt was.

Still rocking mine at 1200/1500. Probably waiting for Pascal and 400 series on something under 28nm.

Hi guys. Can you give me your MSI afterburner settings? Because i get 70+ temp on Low Settings while playing CS:GO and 85C on Dota2 which is really frightening. I even tried running the 3dMark thingy and it reaches 90+ temps so i kept cancelling it.

I don't mind to give you my stable clocks, but I doubt it will be useful to you, every card is different, mine is a Sapphire Dual X (Asic 63.4%):
1100/1450@1150mv = ok; Temps: 66/81°(vrm) in Heaven
1000/1400@1100mv = ok; Temps: 63/74° in Heaven
My fan speed never goes above 40% and I'm fine with these settings, powerful and silent,

here is an example of painful setting for my card:
1170/1450@1200mv Temps: 70/92° in Heaven, stable in benchmarks, but requires a lot more air, 50%+, noisy, and some strange lags appear in BF4,
Hope it helps, and my advice according to my observation, you should definitely play with downvolting, original voltage of 1.256mV is far too high for these cards.
