After publishing this post, I was alerted to the fact that there are some AM5 motherboards that do officially support ECC. ASRock's Rack line supports it, for example: https://www.asrockrack.com/general/productdetail.asp?Model=1U4LW-B650/2L2T#Specifications https://www.asrockrack.com/general/productdetail.asp?Model=1... This ASUS motherboard also claims to support ECC: https://www.asus.com/us/motherboards-components/motherboards/proart/proart-x670e-creator-wifi/techspec/ https://www.asus.com/us/motherboards-components/motherboards... Neither of those were out at the time I originally got my AM5 motherboard (which was right as they came out -- the performance numbers were so good I couldn't help but spring on one early.)

  The Asrock Racks, 1U4LW-B650/2L2T, 10g ports appear to be supported by VMWare ESXI 8: https://www.vmware.com/resources/compatibility/detail.php?deviceCategory=io&productid=43270 https://www.vmware.com/resources/compatibility/detail.php?de... I would be interested in hearing someones experience with getting this board running as a type 1 ESXI hypervisor.

It was really iffy and not clearly mentioned until this year. Also, it's confused with on-chip ECC which all DDR5 uses. DDR5 needs on chip ECC to correct errors that'll occur in normal operation but that won't provide ECC for transfers across the memory bus to the CPU.

> Had no idea that 7000s series doesn’t official state support of ECC. You've misinterpreted the author. All currently-available Ryzen 7000 series CPUs have official ECC support, but it requires motherboard support as well.[1] This conditional ECC support has been the case for all past AMD consumer CPUs going back to the original Athlon 64, but the Ryzen 7000 series is the first time I can recall that this support has been explicitly listed on AMD's marketing materials. What the author is saying is that mention of ECC support had disappeared from ASRock's motherboard documentation. This was a notable change for ASRock, as they had explicitly mentioned ECC support on their previous Ryzen motherboards.
