My former colleague Christian Hirsch (not CCed) can reproduce the
problem reliably. He today switched the CPU to a Ryzen 7 7700 and later
to some Ryzen 9600X – and with those things worked just fine, e.g. no
corruptions. But they came back after putting the 8600G back in.

Ralph, can you please add this detail to the Asrock support ticket?

Ciao, Thorsten

[1] he described building a x600 machine in the c't magazine, which is
the reason why I and a few others affected and CCed build their x600 systems
