You should always check that first.
The stock bios wasn't able to clock past the 862 limit, and I have successfully flashed and can clock up to 885 now.

Some wierd things are happening, GPU-Z can't identify Crossfire being enabled, and I am not able to clock the 2nd card with Rivatuner when in Crossfire mode.

3dMark06 scores are similar to the stock bios, at around 18,500, with Crossfire. Has anyone else had problems seeing their crossfire in GPU-Z, and/or being able to clock the 2nd card with Rivatuner?

I suppose I've been successful, enabling higher clocks - but I can't see any real-world benefits yet.

WTB voltmod?
