Hi all!
I got two toxic hd 6850, but as you may know the CCC oc limit is set to 850/1200 and if i try to use tools like afterburner and trixx i'll only get instant freezes (i'm in crossfire, i also tried to disable ULPS)

so i heard about a bios flash from 6850 to 6870, but i didn't found nothing intresting like guides etc.. and it is risky

the other option is to flash each card with their own bioses with a 6870 frequencies and voltages, or just unlock the overdrive limit

do you think that this is worth the efforts? wich is the best way in you opinion?

Cheers

Whoops... that was embarrassing...:banghead::ohwell:
I would leave it for now and see if any new breakthroughs or guides emerge, and that a good sized handful of people claim and show proof of that this could happen
