AMD 7950 3GB Linux Mint 19.3 no open cl

It seems that a lot of GPU problems revolve around specific versions of drivers. Though AMD has their own support structure, you can often learn from information reported by others who fold.

Steam would be using OpenGL, not OpenCL. People have mentioned some utilities such as clinfo, but those I never got into using. To se if the GPU can do basic OpenCL as used by folding, there is FAHBench. It is a benchmark based on the Core_21 code and has a copy of an olde WU to process. If drivers and support installed can run that, it is a start towards getting a GPU to process for F@h.

It seems to me that you never installed ocl-icd-opencl-dev -package.

Just google where you can download it and just double click it in downloaded folder just like in windows. If that is the place you saved it (default).

Screenshot of the fahbench.

It won't detect my 7950.

To be honest, I'll probably just put Windows 10 on it. I created a bootable usb in linux mint, so that will probably be it.

I wish linux was really ready for everything because I love how fast and responsive linux mint 19.3 is. It's a great OS, just not with AMD GPU's and f@h.

Have you checked from driver manager if there is another driver to install? (You must remove recent first).

I run Mint on all of my CPU/Nvidia folding rigs. Tried to build an AMD GPU rig and quit after two days of fighting it. I think the key is finding an older version of AMD's official drivers that have OpenCL and that will work. Sadly, I'll just have to install Windows for now.
