    4870x2 issue

    empty_knapsack
      Only first GPU goes full speed while 2nd stays in 2D mode

      Anybode else got that problem?

      Starting ATI Stream application on both cores of 4870x2 results in that only first core goes from 2D to 3D mode and so running at 750Mhz clock rate while 2nd core stays in 2D mode with only 507Mhz speed.

      2nd core can be forced to run with 750Mhz clock rate simply by starting in parallel some 3D application so driver starts to think that it needs both cores at max speed, not only first.

      I guess it's another driver issue...
