Unable to stabilize 5900X running with PBO and Curve Optimizer

Motherboard: MSI B550 Unify running BIOS version 7D13v132 (beta)
Processor: 5900X

Problem: I am unable to get a stable system using PBO and Curve Optimizer with this system even setting the offset to a positive value for cores that throw MCE (machine check errors). 

If I disable PBO and CO entirely, the machine is stable so I am thinking that either PBO/CO is buggy or I do not have it set up correctly.

I initially set all cores to -15 and all other settings left alone.  It runs stable doing CPU intensive things like prime95 or compiling with gcc, but when I do very light work loads, I get MCE errors.  I have been reducing the negative offset of affected CPUs but ultimately changed from negative to positive and am still getting MCE errors on light workloads.

Is there some other setting I need to manually define beyond:

A-XMP profile 1 setting for the memory.

PBO to Advanced and defined the PBO Limits to Manual with following:

PPT=142

TDC=95

EDC=120

The only modification beyond that was setting Curve Optimizer to Per Core and settings all cores to -15 to start with.  Again, I have been giving the affected CPUs +15 values but am still getting MCEs.
