    Dual 5870's

    I have two of them, one is a 1GB and the second is a 2mb. Is there a way for Moo to recognize both of them? I scanned through the board and I see others doing it but I didn't find a thread that indicated how to do it. Currently the 1GB is crunching and the other is sitting on my desk

    Thanks,

    Philly/Dan

    Does BOINCmanager see them both? Check the messages, scroll back to the beginning. It will tell you what HW it sees.

    A dumb question: When you brought the 2nd card up did you "extend" the desktop to the 2nd card so it would be found by Windows? You MUST have a VGA dummy plug or a monitor on the 2nd card also.

    Also, when multiple GPUs are present, BOINC may only use the faster one. Since yours are not exactly the same, that may be the case. In the <options> section of your cc_config.xml file you can add:

    <use_all_gpus>1</use_all_gpus>


    That might do the trick.

    I went to the directory for moowrap.net and there are two xml files: job-ati14-1.00.xml and job-win32-1.2, no cc_config.xml. Should I create one with that line?

    I'm not sure what 'extend' means, sorry, but Windows does recognize both cards.

    I don't have a 2nd monitor so, where might I acquire a dummy plug?

    Re: Dual 5870's

    Also, any idea why the file dnetc518-win32-x86-stream.exe is using 90%+ of the cpu? I don't seem to remember any file doing that in the past. I'm not crunching any WU's on the processor, just the GPU.

    EDIT: I took one of the GPU's out and the file went back to 0% to 2%. Hmmmmmm.

    EDIT AGAIN: This work unit took similar run time to all my other ones, but when that file was using the cpu @ 100% the CPU time equaled the run time, which is not consistent with my other WU's, which were much lower.

    http://www.geeks3d.com/20091230/vga-...ga-dummy-plug/ ... you still will have to Enable the Second Card in the ATI Catalyst Control Center to get them both to work ...

    EDIT: Forgot to mention that the Resistor's can be bought at any Radio Shack Store ...

    We have some good info in the FAQ under GPU crunching, including how to make a dummy plug.
