Apparently my CPU has low utilization, a low score on cinebench R23, and have PPT TDC maxed out at ~25% and EDC maxed out at 40% under load ?
What are you considering 'max performance'?
Low CB23 scores could be inadequate cooling since Ryzen is so temperature sensitive.
Memory running at default clocks (2133) can also hurt performance. Try resetting CMOS and then enabling XMP or DOCP profile.
I'd also suggest dumping RyzenMaster. It's known to harm performance, especially if running at the same time you're running a benchmark. Uninstall it since it's service is also a problem even if the app isn't running. For monitoring get HWInfo64 instead.
