I have ECC RAM installed on my Gigabyte B550I system. dmidecode shows the 72 bit width (Total Width: 72 bits) and dmesg | grep -i EDAC does show a bunch of info suggesting ECC is enabled. But this command's output is empty:
No Memory errors.
No PCIe AER errors.
No Extlog errors.
No MCE errors.
Do I need to enable something so these errors get logged or have I been misled by dmidecode and dmesg?
- c0l0 3y agoYou 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.
