If you often wonder why your CPU never seems to achieve the boost clocks it’s advertised for, its power limits might be the reason. The way your motherboard manufacturer tunes the BIOS can hold your CPU back, even if you have a capable cooling solution on your PC. Your CPU has multiple power limits that work in tandem to determine the boundary conditions within which it operates. You can often tweak these limits in the BIOS/UEFI, changing your processor’s behavior. However, you need to understand how they function before you can do that.
