How do i OverClock my PC, Here are my specs if it is even possible.

I am trying to run valorant at atleast a steady 60 fps, i can get upto 40- 45 at the momentI am not aware of a way to OC the A8 you have on hand. This is a CPU that wasn't particularly strong when released and certainly hasn't aged out well.
What are you trying to do with it that you feel an overclock is desirable?
