Alright guys, for a starter I know my 4870x2 setup works fine with both cores. I see confused people in this thread so I made 2 screenies of my CCC:
It IS correct that you see only 1 graphics adapter for the 4870x2.
For GPUs it should list 2 GPUS. One has the monitor [Syncmaster] attached, the other has nothing attached. So yes, correct. Only 1 monitor.
Current clockspeeds shown are those of an idle card, nothing wrong with this.
I've slightly overclocked both cores to 777 core, 950 memory. Don't try to match my settings, they may not work with your card (run too hot).
