I'm using a Fuzion GPU block, 30ºC idle 33ºC full load. With the original BIOS it maxed out at 870-880, with this one I'm rock stable in games at 890 stock volts. Artifact free in ATITool is about 860-865. Temps are very important with this card, with the stock cooler the max was 820 or so. I'm also using the red plate where the stock cooler is attached to cool the RAM and the mosfets, no need for more. In fact I think this red thing is more efficient dissipating heat from the mosfets than the Enzotechs, but who knows.

BTW Overdrive is so much better than AMD GPU Tool/BIOS flashing for changing the clocks
