I just bought ryzen 3 1200af for fun just to overclock it. I actually can to some point. Online i saw that others went to like 4.0 ghz or somerhing like that and i tried first 3.9. The multyplier is 39 but the actual clock is 3.45(max turbo clock). In task manager cpu usage maxes out at like 86% and wont go higher but it says that the base clock is 3.9. In HWMonitor is 3.45 and just locked in. I updated the bios, i changed the voltages and still cant move that.
