    I have a 6 Core PhenomII CPU + a AMD HD5850 GPU...running Win7x64.

    When all 6 CPU cores are working, the GPU comes up to 2% load. When 5 CPUs working, GPU comes to 65%.

    How can I configure BOINC for the maximum? (6CPUs + 100% GPU load)

      Short answer: You can't get 100% GPU and 100% CPU

      Long answer: A GPU application will always need help from the CPU when running. Some applications need more help than others. The E@H BRP5 application need a lot of help.
      To optimize your machine I suggest you turn off all CPU tasks. Then you add GPU tasks until you reach 90%+ utilization on your GPU (or you run out of memory on the GPU). After that you can start adding back CPU tasks until you notice the GPU utilization starts dropping. That is your maximum.

        My recommendations for a Phenom II X6: leave 2 CPU cores idle and run 2x GPU WUs.
