I'm new , I don't know anything about OC (I'm stupid :))))) )

This guy uses this method to cheat in the game, I want to ask how to do it to see if it's special if done in the game.

he uses a K chip and a Z main, does anyone know how to keep the clock speed at a certain number without changing like that on Intel and can you guide me? I'm currently using B650 + 7800x3d, is it possible or do I need a chip that supports overclocking (as far as I know, 7800x3d cannot be unlocked for overclocking). Thanks everyone.
