AVX instructions or software have additional targets and limitations that don't take note of these available settings and behaves in their own way. What settings we have available ONLY set the targets for non-AVX loads. There are additional Limits on performance other than the available settings exposed in AMD_CBS & AMD_OVERCLOCKING BIOS pages. Sadly I myself have noted PBO is gimped and performing beyond subpar to expectations. There is TDC & PPT as well, PBO uses these limits to set boosting targets and characteristics. In case of a Ryzen 7 3800X EDC would have a limit of 140A EDC. I have found a little flexibility with this setting but not as flexible as it was previously. Basically only stock or 0 value which equals the processor fused setting is used. Some have complained that it would not work period. Some folks have probably noted there have been a bug in regard to EDC in the newer AGESA 1.0.0.4B BIOS. PPT & TDC aren't important as they can be set whatever you want really but the key aspect here is EDC.

*EDC 20 is for 3950X, EDC 30 is for 3960X, see bottom of post for other samples LINKĬnQ enabled* *board maker specific, not all brands use it Some posters over at the X570 Crosshair VIII thread came upon a way to get PBO to boost like never before.
