    ./CLinfo   Max clock frequency:                           0Mhz

    zeland

      why ./CLinfo shows

      Max clock frequency: 0Mhz

       I've uesd sdk 2.1(10.7) or sdk 2.2(10.7b, 10.8) OpenSUSE 11.2 x64, but in any case it shows  0Mhz

      My system two ATI HD5870 and NVIDIA gtx 470.

      It shows normal informations for cpu or NVIDIA GPU
