6850 Overclocking

post #1 of 2
Thread Starter 
Hello OCN,
I just bought a Sapphire 6850 Radeon for my computer, because my 3870 just doesn't cut it anymore. I wanted to know what kind of overclocks you guys have been able to get with this card or and 6850 for that matter, and what kind of performance boosts do you see with your overclocks? Also throw in other relevant information such as temps, after-market cooling if used, and the setting you run you benchmarks on. Thanks.

When I get my 6850, I will do some overclocking and post my results on this thread too.

Max stable OC I achieved was 900mhz on stock volts and 930mhz with a slight voltage bump. My card is a stinker. I spent one day on it so I should be able to bump it up some more when I get my PC back. With an OC and voltage bump this card gets up to about 85C in my oven for a case.

But my card has a VID of 1.149 and I was able to undervolt it all the way down to 0.987v stable on stock clocks. Runs extremely cool at these settings, about 70C in furmark after 15 mins.
