I didn't consider embedded CPUs (I guess that's about an embedded EPYC, not a server one), those look neat. But there's no official ECC support (i.e., it's similar to Ryzen CPUs), is there?
Edit: as detaro mentioned in the reply, there is, and here's the source [0] -- that's what they mean by "RAS" on promotional pages [1]. That indeed looks like a nice option.

- loeg 6y agoRAS covers more than just DRAM, but yes. Historically, the reporting interface is called MCA (Machine Check Architecture) / MCE. I think both AMD and Intel have extensions with other names, but MCA/MCE points you in the right direction.
- detaro 6y agoAll EPYC, including the embedded ones, do officially have ECC support
- adrian_b 6y agoFor embedded applications, there is official ECC support for all CPUs named Epyc or Ryzen Vxxxx or Ryzen Rxxxx. There are computers in the Intel NUC form factor, with ECC support (e.g. with Ryzen V2718), e.g from ASRock Industrial.
