Greetings,

I've done various searches on these forums as well as google and cannot find any help for this issue..

I'm running BOINC 6.10.58

I have a homebuilt Core 2 Quad system with:
Primary Graphics: ATI Radeon 5870
Secondary: Nvidia Geforce GT 240

I have monitors enabled on both cards.

When I open BOINC, it detects the NVIDIA GPU no problem, but not the ATI GPU. Seti@Home will then process units for the Nvidia GPU.

If I go into Device Manager and disable the NVIDIA GPU, and re-open BOINC, it sees the ATI GPU and processes work units for it (Milkyway@Home). Of course, it does not detect the NVIDIA GPU when disabled.

Does anyone have any recommendations on how to fix this? I'm running Win 7 x64.

To recap:
- IF both GPUs are enabled, BOINC only sees the NVIDIA GPU.
- If the Nvidia card is disabled, BOINC THEN sees the ATI GPU.

Any/all help appreciated.

Thanks,
John H

OK, This worked - I guess I didn't read that thread thoroughly enough before. Thank you :)
