My fan's dont respond to the -tt -90 code. No idea what is going on. As long as my room is cooled, the xfx's will run 29 mhash. But when it gets hot they will (throttle?) run 25-27mhash.
I also have the issue with my sapphire's. I tried to mod the rom, went wrong, flashed the original bios rom back, cards are running smoothly 27mhash 80 watt but i cant see temp or clock's. HOW?
