I am running a Windows 10 machine with a NVIDIA GTX 750 TI and recently added a second GPU, a NIVIDA GTX 1050 TI. It is not recognized by BOINC and Windows Device Manager shows a "Code 43" error. And windows does not find it as a second display. I installed a new NVIDIA driver -- no change. Tried running it with and without a "dummy" HDMI plug -- no change. It seems to be recognized by GPU-Z, but it shows the same GPU usage as for the 750 which I don't believe is correct. I don't see any BIOS settings dealing with multiple GPU cards.

Here is a copy of my cc_config.xml file:
<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
<exclude_gpu>
<url>asteroidsathome.net/boinc</url>
<device_num>1</device_num>
</exclude_gpu>
</options>
</cc_config>
I don't want Astroids to run in the 750 because it impacts the display too much.

Any suggestions??

I have decided that the board is defective and will return it for a replacement.

Update?

Received a replacement GTX 1050 TI -- Runing fine along with my old GTX 750 TI.
