Huge performance drop after CPU overclock

[sebback]

I overclocked my Ryzen 5 1600 and looking at benchmarks it looked like it was nice performance boost but once I tried to actually play a game I got unplayable framerates. 5-10fps in cyberpunk 2077 which before OC was a pretty stable 60fps at the same settings. I thought it might be unstable, but when I reset everything to normal settings the performance was still equally bad, even desktop apps are much slower. I overclocked to to 3.7GHz at 1.3V, ran kinda hot at 86C while running cinebench but as far as I could tell it didn't seem to be thermal throttling. Other games are also much laggier than before, CSGO and Witcher 3, but AC4 runs fine since it seem to not be very cpu heavy.

 

What really confuses me is that the performance was alright before, but now it's much worse even at the same default settings as before. If anyone could help identify and solve the issue I would greatly appreciate it.

Don't you mean 3.7 GHz?

3.7 MHz is around the speed of the ZX80.
