    Is that on idle? CCC will throttle down clock speeds when you are idle to save battery life and have less heat.

    thanks for the reply, well i left hwin32 running in the back round while i played crysis 2 to test is out, feels like theres no extra performance when cf enabled,, it says now gpu 2 clocks are 67 and memory at 54, guessing these are the 2d clocks, i have tried ati gpu tool to try and get them to running at 550/888 but it says clock settings failed, but it lets me change GPU 1 clocks but not GPU 2

    Are you using custom vbios's? Ever since I started using Custom vbios's for my 4870's gpu-z, hwinfo and other programs sometimes have trouble reading the correct clock speeds (even though the cards are operating correctly.)

    As far as I know there the standard vbios, gpuz is the only thing that reads the second gpu as 550/888, downloaded speccy, and it says crossfire is disable, but in ccc is enabled, in ati tool, it won't let me over clock the second gpu at all, fought I could see if it could run at 550/888,
    Tried doing 300/400 wouldn't let me but, it let's me do the first gpu

    As far as I know, you can't use ATI tool to OC the second gpu (might only apply to 4870's). You have to use Rivatuner.

    That's what i had to do b/c ATI tool wouldn't do it.

    Ive noticed ecaxctly the same on my second 4870 , i think its a glitch with Hw Info .
    GPU-Z shows the correct clock speed on mine , heres a screen image just taken .
