I've popped back to see what my latest addition to my small farm of computers will do.

It has two GPU's a GTX 960 and a GTX 970, yet is is only showing 1 GPU running at 0.2 CPU + 1 Nvidia GPU. Also twin Xeon Hex core processors (24 cores)

What I want is to use both GPU's and at 1 CPU + 1 GPU. I can do this at Seti@home with an App_config file.

Anyone got one for here?
I iz also got icons!

Since they are same brands, it should work. You may need to tell BOINC Client to use both and not only "best one" with use_all_gpus setting in the cc_config.xml file. (Please refer to https://boinc.berkeley.edu/wiki/Client_configuration for details.)

Hmm, looking at your computers, looks like you don't have OpenCL so we are only using cuda31 apps. This means our v1.3 app crunch on both cards with one process. I can see many WUs with "device: 2 x GeForce GTX 960" from our wrapper and "Automatic processor detection found 2 processors." from D.net Client so it was at least working for some WUs. Not sure what you have been trying to do configuration wise as some do indeed seem to see only one card.
