from my experience i used msi afterburener to overclock my pc but my pc crashed every time and stopped working, luckily after i fixed it i found out ThrottleStop
I've used it for the past 2 years, and i freaking mean it my cpu went from barely running anything to running many modern games… from 1.5 GHz to 3.58 GHz with no overheating is quit impressive. so i js here helping if anyone wants to overclock their cpu safely , i recommend ThrottleStop
