Wait, what? ECC RAM for a consumer CPU? Does anyone sell motherboards like that?

Asrock Rack and Supermico sell AM4/AM5 motherboards with support for ECC UDIMMs. Other vendors might state official support on workstation-class motherboards, and in general it might work even on motherboards without official support.

Literally first Asrock motherboard I happened to click on has it listed as a feature: https://www.asrock.com/mb/AMD/X870%20Taichi%20Creator/index.asp#Specification https://www.asrock.com/mb/AMD/X870%20Taichi%20Creator/index.... Asus has options as well such as https://www.asus.com/motherboards-components/motherboards/proart/proart-x870e-creator-wifi/techspec/ https://www.asus.com/motherboards-components/motherboards/pr... I think it was more rare when AM5 first came out, there were a bunch of ECC supported consumer boards for AM4 and threadripper.

AMDs I/O die supports ECC RAM, but up to motherboard vendor to run the required traces. Some do, some don't.

"Consumer" shouldn't mean garbage. Between random bit flips in an environment where you have 16 GiB of RAM or more (common in gaming setups now) and Rowhammer, ECC should be the standard. It's only not so that chip and RAM vendors can bin and charge a premium for the good stuff.

I have 2 Supermicro H13SAE-MF with Ryzen 9's and ECC UDIMM RAM. It's not registered or LR ECC RAM like a mainstream server though, and not as fancy as Chipkill-like ECC systems. This particular board also accepts EPYC 4004 / 4005 series. I'll probably replace the Ryzens with EPYC 4585PX once they get old enough and cheap enough on the secondary markets. These boxes are 100 Gbps network test nodes. (I'm currently in the midst of refanning my CSE847-JBOD with bigger, quieter fans and swapping PSUs.)
