    Please forgive my poor Englinsh.

    I'm a supporter of Einstein@home. I am running on 10 computers to Einstein@home.

    I changed my computer to Lenovo z585 yesterday.

    This computer have APU so it have GPU unit on CPU, and it have another GPU.

    (AMD A8-4500M APU, RADEON 7640G + 7670M DUAL GRAPHICS)

    I installed BOINC , and turned GPU opttion to ON, I'm plaesed with processing Speed with GPU.

    But, I think that only 1GPU is working, and another GPU is in idle.

    It seems that GPU unit in APU(7640G) is working but independent chip(7670M) is not working.

    How can I let the independet chip work?

    And Can I control the GPU on crossfire X?

    For example, User turn GPU unint on APU to off and independent Chip to on.

    I think there is no contol option to GPUs In BOINC in current version.

      Hi!

      A good FAQ for tweaking GPU support in BOINC can be found here:

      http://boincfaq.mundayweb.com/index.php?language=1&view=471

      Scoll down to "I have 4 GPUs" for your specific question, but the rest of the FAQ is very useful as well.

      Cheers
