I have 3 video cards in my machine yet only two of them are showing up with tasks running. Is there anything I can do to make it utilize all my GPU's?

What projects do you have running? Even though your two nVida cards are from the same family, they may have different features (memory, OpenCL compatibility, double-precision, etc) that prevent them from running the same projects. You could use the results at WUprop to see what other people are successfully running on each of your cards.

You'll need a cc_config file with a <use_all_gpus> tag in it to get the two Nvidia cards working. See the doco for details. I would cut and paste one except I'm typing this on a phone in a moving bus :-(

How many GPUs does Boinc detect? You may need to extend your desktop onto one of them to get Boinc to detect it.

Creating a cc_config with hose values worked. Thank you.
