The GT 520 was marked down and the GTX 570 is mark available and used for computation

You can tell BOINC which GPU to use by setting up a cc_config.xml file. Look for <use_all_gpus> and <ignore_cuda_dev> or <ignore_nvidia_dev>, respectively (depending on your BOINC version).

I used the following configuration file in the BOINC data directory to mark the GT 520 as Not Used:

<cc_config>
<options>
<ignore_nvidia_dev>1</ignore_nvidia_dev>
</options>
</cc_config>

LOL... Only NVIDIA would mark a $60 dollar GPU higher than the $350 dollar GPU. To alleviate my problem, I bought another GTX 570 SC for SLI and will use it as my secondary video card. Hurt the pocket, but BOINC wins with an additional job with GPU power of 1530 GFLOPS

Thanks for Info

I don't know where to find my cc_config.xml. I searched my installed drive and did not find file that file name.

BOINC 7.0.11 also declared the wrong GPU Not Used.

When I added a second video card(GT 520) to system, my first video card(GTX 570) is marked as NOT USED during the initialization of BOINC program. BOINC then uses the second video card for the single job.

When I disable the GT 520 via the device manager, BOINC marks the GTX 570 as okay during initialization and uses the video card for the job.

Currently using version 7.0.8 of BOINC. I don't think the problem occurred when I had a secondary video card of a GT 220.
