I dont know does temperatures affect on artifacts (atleast I haven't noticed so), but too less voltage tends to make artifacts. And 82c isnt usually too high temp, so try to bump a notch your voltage to see if you get rid of your artifacts, or lower clocks?

1285 stable until 82C is actually really good. Usually that high a clock requires temps below 70 from what I've seen. Not to mention that most chips don't get there no matter what temps and voltage...

man back off the overclocks. 1285 mhz on a reference cooler is crazy stuff. in fact its very rare that you can hit 1250+ Mhz at 82 c. mostly you need to keep temps around 70c for hitting those 1250+ mhz overclocks. with the accelero you should be able to keep temps below 70c on max fan speed. the accelero fans are very quiet. so max them out and get your temps as low as possible. for stability at high overclock keeping temps as low as possible is essential.

Oh wow, I didn't know that about the temps! That would explain the problems I've been having recently.

I was running 1225mhz @ 1.37v stable on one screen, but as soon as I moved up to eyefinity it started ****ting bricks. Thats prob cause multiple monitors cause higher temps...

Is there a cheap-ish way to keep temps down on this card? I thought about the accelero, but even at 80$ thats pretty steep

edit: Im still on 12.6 catalyst, should i update

Get 12.11, pretty big performance boost for several games. About the cooling, if the Accelero is too expensive, i doubt there is something cheaper to cool them. Make sure your case has good airflow, that sure helps.

I've been tempted to give this one a try myself:

Seems to perform quite well:

yeah get the latest 12.11 beta 8 drivers and 12.10 CAP 1.

http://support.amd.com/us/gpudownload/windows/Pages/radeonaiw_vista64.aspx

as for cooling the accelero xtreme is the one to get. if you are serious about 1200 mhz clocks thats the minimum quality of cooling you will need to maintain stability especially with multi monitor.

www.newegg.com/Product/Product.aspx?Item=N82E16835186064

http://www.xbitlabs.com/articles/coolers/display/arctic-accelero-xtreme-7970_5.html#sect1

60c core temps, 68c VRM temps , 60c memory temps on HD 7970 Lightning at 1140 Mhz at max fan speed of 2100 rpm. but the card is quiet even at max fan speeds.

http://www.xbitlabs.com/articles/coolers/display/arctic-accelero-xtreme-7970_6.html#sect0

with multi monitor the temps will be higher. but you should still be able to keep core temps around 70c or lesser.

This is old news to most probably.

But I was just cleaning my computer and noticed, I have a Dual BIOS switch on my TF3 7950. Huh!. Never noticed it before.
Who can tell me which position is which BIOS or which one is flashable?
