Well, that's a different segment, you won't find Dell selling you a 3900X and ECC in a server or workstation either. But OEMs like SuperMicro and Asrock Rack do officially support this, and sell barebones or pre-configured systems like this. https://www.supermicro.com/en/products/motherboard/X11SCH-LN4F https://www.supermicro.com/en/products/motherboard/X11SCH-LN... https://www.supermicro.com/en/products/system/1U/5019/SYS-5019S-WR.cfm https://www.supermicro.com/en/products/system/1U/5019/SYS-50... Workstation: https://www.asrockrack.com/general/productdetail.asp?Model=C236%20WSI https://www.asrockrack.com/general/productdetail.asp?Model=C... (and to be fair, Asrock Rack does have a few AM4 server boards and barebones, and these are among the few I would count on to actually validate ECC. It really just is something you have to explicitly go out of you way to find support for in the AMD ecosystem, whereas it's "free" on any C2xx server board in the Intel ecosystem, the default assumption is that it works because it's considered a supported configuration and that's not the case with AMD.) https://www.asrockrack.com/general/productdetail.asp?Model=X470D4U#Specifications https://www.asrockrack.com/general/productdetail.asp?Model=X... https://www.asrockrack.com/general/productdetail.asp?Model=1U4LW-X470#Specifications https://www.asrockrack.com/general/productdetail.asp?Model=1...
