I use CoreCycler to test my PBO. I started at -30 for all cores, and increased it by one for every error/crash. With the current configuration, I ran six iterations of Prime95, with "Large" and "Moderate". It is stable. However, I can not believe, that a -29 is reasonable. What do you think?

Stop using Ryzen Master.
IIRC my 5900X varied between -8 and -30 between its cores, so it’s not too far fetched. Although the -30 was only stable on one or two of the cores.
Basically you would also still need to test more, and also switch up the test settings, e.g. check with Prime95 SSE Huge, and y-cruncher with `19-ZN2 ~ Kagari`.
CoreCycler also has an automatic test mode now, which will reduce the CO undervolt on its own if it encounters an error. You could use this to let it run over night and abort and check the results in the morning.
