Pc won't work in games



I do agree ryzen likes faster ram, but in the case of 2400mhz v 3200mhz, the difference in gaming FPS is typically 5-10%. Sometimes more. But that often translates to just a few FPS, so that's not the problem here. It won't impact the overall performance of the GPU too much. If the games don't run at all, there is something else at play.

Agree, about which games the OP is playing.
