I am currently looking for a biostar 5870 bios. I flashed it with new bios, but did not save the old one. I tried other bios but the clocks aren't the same as them. clocks are 850/1250 and nowhere can i find a stock bios like that. Im trying to run the card in tr-fire with 5970. It was previuiosly running in crossfire with a 5850. when booting and the card is detected in windows, it freezes.
