Task Manager show my 2nd gpu is not running, can anyone help?
I did turn off my SLI, and make sure I check "use all GPU"

Be sure by doing render tests for selecting the one vs. two gpu on renders. You can compare render speed and times.

My 2nd GPU showed 0%, and 1st gpu is the only one running from 15% to 90%.

I mean be sure that's really not used by renderer. How do u know octane is not using second gpu? You can check gpu usage in render image. Check bottom line of render image for green gpu bars.

oh thanks Aoktar, I downloaded GPU-Z to check, an realize both GPUs are running.
Just curious why task manager only show 1st gpu running, but not the 2nd gpu.
