L3 cache read speed punished by PBO

5950x, B550 Unify, GSKILL F4-3600C14-16GTZN
With PBO disabled


With PBO enabled


I realize my secondary timings were sloppy, that's just what you get when everything is left on auto.
Well, here is what happens when the timings are tuned


It improves a little but still considerably worse than with PBO disabled.


Can someone enlighten me a little as to how to fix this?

PBO has been tested by a number of reviewers and found to be pretty worthless. Just marketing hype.

Were you running 51x (all core) with that first PBO disabled screen shot?

Have you tried to run run/stabilize your memory with higher 3733/3800 speeds 1/1 @C16?

I'm currently trying to dial in settings @3733C16... I have doubts about being able to stabilize my chip @3800MHz.

This is PBO (4x8GB):

That's tastefully disgusting

That L1 performance is pretty sick
