Folding Forum

I cannot add a GPU in the Configuration and this PC is only folding with the CPU.

You will need to keep a few things in mind:

1) Make sure you have the most recent AMD drivers for the Radeon series card. Windows users can go here to download a utility that will detect your AMD card, and help you download the package you need: https://www.amd.com/en/support. The OpenCL driver libraries will be part of this package (F@H and other distributive computing projects require v1.2).

2) AMD GPU's/iGPU's will **NOT** support CUDA--That is exclusively an NVidia GPU/iGPU technology at this time. Any error messages you see in the logs that are related to CUDA library files not being detected for your AMD card can be ignored.

3) You must be running F@H at full power, and have removed the expert configuration option in FAHControl: 'gpu false'.

Hope this helps.

Also, if it is still not folding on the GPU (or folding performance appears sluggish) after you have checked all of the above, you may need to go into the advanced Windows 10 settings for power saving and select "High Performance". Also, look deeper for other power control option settings--focus on the ones that are related to PCI Express Link State Power Management (turn it off); Minimum and Maximum processor power state (set both for 100%).

I am standing corrected here. The AMD Drivers Package does not include OpenCL. You can obtain it here: https://github.com/GPUOpen-LibrariesAnd ... ht_AMD.exe

Should one of the forum members who is using an AMD card to fold have a better source (or better information), I will let them follow up with you.
