System Tools Cannot Recognize K40c as the Second GPU

Accelerated Computing CUDA CUDA Setup and Installation
#1

I am using the Quadro K420 and Tesla K40c in my workstation. However, the K40c cannot be recognized and configured as the second GPU by some system tools, like nvidia control panel, nvidia inspector.

I try different versions of the display drivers, but they are not effective to recognize the K40c.

Any suggestion?

Thanks a lot.

It’s not clear what you are having difficulty with. Are you able to run the cuda deviceQuery sample code and see the K40c reported?
