    This is my first ever double video card setup. 2 x 5850. 11.9 cats. Crossfire enabled. No messages in Diagnostics.

    in both CCC and GPUz the second card readings are strange. like zero clocks when idle and 157 gpu / 400 mem / 0% load when run a 3D application .... is that normal or i should be seeing the same clocks (725 / 1000, stock 5850 clocks) in both GPUs and some load on the second card ?

    sometimes CCC will show zero or 157 on second GPU while a 3D application is running while for example GPUz will be showing for the same card, 400 GPU speed, again no GPU load ...

    Thanks!

    Its normal, and also CrossfireX only becomes active in full screen games, if they are Windowed it will drop back to 1 card only ;)

    There's a power saving function, who disable the second video card when not in use ( UPLS in register windows ) ... when you are under normal windows operation, the second card is power off ( power saving ) ...

    So basically, when you are under windows and just browse internet, only the first gpu will work , when you enter an intensive task ( game or software who need it ) the second gpu will wake up.


    By editing the register, you can set UPLS to off, and so both cards are acting //power on, all the time......... ( 157mhz / 300 inidlle and full clock when needed )
