nouveau doesn't support compute at all on those... (as in OpenCL).
Also, as far as I remember, rechecking work on Fermi didn't seem to be implemented the last time that I played with one (it is implemented for the later generation, Kepler, though)

If your app is compiled against CUDA 8.0 or earlier, targeting compute capability 2.1, it'll work on Fermi. That excludes any kind of modern binaries.
(the newest compiler that CUDA 8 supported was GCC 5.3...)
More recent apps can either be built with an old compiler + C++ library... or use OpenCL instead.
Thanks again - I appreciate these details. Blender's not seeing cores available for OpenCL, either.

I'll research Fermi for OpenCL and Cycles Render Devices. Blender's working well, so I'll resist the urge tweak until that's no longer the case, and hope to spend more time exploring 2.92.
