I am wondering, as I returned to Milkyway, with my two GTX 780 ti cards, why am I able to run only one of them on Milkyway at a time? On all the other projects it runs both. Perhaps I did not check off a box?
Appreciate any help.

Have you tried putting an app_config file into your MW project folder?

Thank you for your reply. But, all the other projects(Seti, GPUGrid, PrimeGrid and Rainbow) recognize both GPU's.

SOME projects don't like 2 Nvidia gpu's in one machine, I don't remember if this is one of them or not. What you could do is have one gpu crunch for here and have the other one crunch for some other project thru an exclusion file like this:

<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
<exclude_gpu>
<url>http://www.primegrid.com/</url>
<device_num>0</device_num>
</exclude_gpu>
<exclude_gpu>
<url>http://milkyway.cs.rpi.edu/milkyway/</url>
<device_num>1</device_num>
</exclude_gpu>
</options>
</cc_config>

The above file will exclude gpu #0 from Prime Grid and exclude gpu #1 from Milkyway, that should get one of your gpu's working here.
