I thought that I read somewhere that the non-X Ryzen cpu's do not offer any ECC capability, but apparently your TrueNAS does show up with ECC.
Does anyone here know how to find error correction events in the logs of Truenas Scale?
Not sure if that ensures "full ECC" functionality but if I query:
Code:
dmidecode -t memory


In my proxmox shell I get "multi-bit ECC":
Code:
Handle 0x0018, DMI type 16, 23 bytes
Physical Memory Array

And for single slots shows also unregistered:
