I had the same problem but on my desktop setup. I followed the instructions above after trying a variety of things and this worked perfectly. It's really important to not let F@H client download the GPU.txt list, because for some reason, it doesn't update correctly and the client will be unable to detect any additional GPUs or a change in the GPU configuration.

Have you checked temps on your CPU? Perhaps removing and remounting the cooler? Also, if you are using XMP, try disabling this initially. If that works, try a lower speed for your ram, or looser timings than the ones the XMP suggests. Technically the CPU only supports up to 2666MHz, so you might just have a poor memory controller if you are using XMP to go above this. Then obviously, there's things like reinstalling your game(s), checking drivers are up to date, etc.
