Question Struggling to get the max out of my CPU

[Phosfr]

im sorry if this is posted elsewhere.

I have a 7800X3D and am currently trying to use ryzen master (taboo i know) to OC.

when i set all my parameters to max (PPT 420W , TDC 280A and EDC 350A) and run a multi-thread stress test with Cinebench its maxing out at 20% usage on PPT, 19% on TDC and 17% on EDC, which to my untrained brain makes me think the CPU isnt working anywhere near as hard as it can...

1. Does anyone know why?
2. Can somebody point me in the right direction if yes

Let me guess:
7800X3d is a gaming specific processor.
It has a huge cache that can be used to speed up the master thread of a game.

When you run multithreaded benchmarks, that cache is constantly emptied, and performance is not even as good as the underlying 7800 processor.
