There never is a reason to OC a system unless you are trying to see when a system breaks down.
If you want more speed, change settings, don’t run things when not really needed etc so the system can use as much resources as possible to do what yo want.
If that isn’t enough for you, get better/faster hardware.
If you can’t afford/are not willing to pay for it, learn to live with the limitations.

A OC’ed system can cause all kinds of problems.
If unwanted things happen, don’t be surprised.
You have taken a gamble and it can turn out badly.

The power management settings don’t “see” if a system is OC’ed or not.
You can’t expect them to work.
