My CPU is working on AUTO ghz mode in bios, though in hard games like new forza 5 or assassins creed valhalla it seems to be throttling, though in forza horizon 5 it shows around 75 degrees, but ghz drops from 3.6 to ~2 ghz or even less, also CPU-Z benches to normal ryzen 5 1600 (not X model) my CPU shows much worse results, than it should be. What can be the problem? Why its lowering frequency even when it runs on 75 degrees max (according to msi afterburner)? Thanks in advance.
