After upgrading from v77 to v82 and then updating my graphics drivers from 384 to the latest, I’m getting
NVML: Driver/library version mismatch
when running nvidia-smi, and mining no longer works with ethminer just displaying “CUDA: Unknown error”.
Hello, I’ve got an issue similar to yours. nvidia-smi does not show me the error you mention, however, miner log shows me that ethminer does not work and
“CUDA: Unknown error
Error: No usable mining devices found”.
I have Nvidia driver 460.39 + Cuda 11.2.
2 GTX 1070
Does anyone have a clue about what’s going on? Your help will be deeply appreciated!
