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.
