You are just lucky, and your hardware appears to be working without any problems ;) Some/most(?) AM4 boards can enable "PCIe AER" (Advanced Error Reporting) in their firmware, which will tell you about stuff going awry while components are communicating over said bus (but every instance of PCIe error I have ever seen, even on rather faulty hardware, was recoverable/correctable), and rasdaemon will also persist those. I do not know what "Memory errors" are supposed to be, since ECC-related problems will be dropped into the "MCE errors" bucket. Neither do I know what "Extlog errors" are.
