Im running smOS and have the have the same error when running “Mean 31 GTX”.
Driver version is: NVIDIA-SMI 415.13 Driver Version: 415.13 CUDA Version: 10.0
The miner is compiled by smOS so i dont have access to the "grin-miner/cuckoo-miner/src/cuckoo_sys/plugins/CMakeLists.txt ".
Please see my github page for more information.
edit: the cpu is getting an upgrade.
