nVidia CUDA with the wrong video card

In trying to build my first crypto rig I wanted to be able to get it functional with the GPU instead of the CPU.

I had originally installed an nVidia GeForce GT 710 but came to find out later that its not a supported GPU for use with CUDA per developer.nvidia.com.

Lucky for me I had a video card to “Upgrade” to, which was an nVidia GeForce GT 630, which supports Version 2.1 of CUDA-Enabled Compute Capability.

I did have to download and install the nVidia Linux X64 driver, and without knowing that the install required kernel-devel so it could built the driver correctly.

The only thing blocking me is it seemed my build of libxmrig-cuda.so was built with the CUDA 11.6 API and the Linux X64 driver does not support that. In fact, running nvidia-smi tells me that the driver supports CUDA version 11.4, so looks like i’ll have to rebuilt my driver with 11.4.
