Amber20 no longer supports the Fermi architecture:

We did not take this step lightly, but the C2050 dates from 2011, and the
internals of GPUs have changed so much since then that it was not feasible
to continue such support. The performance of more modern GPUs, say going
all the way back to the GTX1080Ti, is at least an order of magnitude better
than the C2050. If money is tight, you might be able to find some bargains
out there for replacement GPUs.
