  > You mean flexibility to claim ECC support but not doing any validation to make sure it actually works? The actual ECC functionality is part of the memory controller, which is entirely AMD's domain. The ECC functionality of the memory controller is fully validated. Whether or not ECC support is present on the rest of the platform is the responsibility of the system builder. However, if the platform isn't fully ECC-capable (e.g., you're using non-ECC DIMMs, the motherboard doesn't have the necessary electrical traces, ECC support is disabled in the UEFI, etc.), this will result in the memory controller disabling ECC support, which is visible to the operating system and is something that you -- the end user -- can verify. > Does any AMD motherboard manufacturer actualy states that "ECC is supported and has been validated"? Yes. ECC support will be listed in the motherboard's spec sheet and manual. There also motherboards marketed for professional use where ECC support is explicitly advertised in the vendor's marketing. > I think the muddy waters that AMD has created would warrant such an explicit statement. AMD's official statement regarding ECC support on Ryzen is that it's supported if the motherboard also supports it. I'm not sure how they can be any clearer without making ECC a mandatory feature of the platform.
