But yeah, when it came time to build my NAS, I went with a low-end EPYC, both for the PCIe lanes for NVMe drives, but also because it's guaranteed proper ECC without having to rely on some "Technically it works, if the board vendor's BIOS plays along, but don't ask for any help if it doesn't" situation with like consumer-Ryzen chips.
Does Intel support ECC? Last I checked it was only their enterprise cpus that did.
What about AMD, they claim to support ECC, but, then tell you that you need a compatible motherboard. Now go on Newegg and try finding an amd motherboard with documented support for ECC. It’s nearly impossible.
And im saying this as someone who has built a few AMD+ECC systems.
And yeah, AMD's Desktop ECC support is sketchy because it's basically "Good luck finding a motherboard that supports it, and also hope the BIOS supports it". That's why I went with EPYC, because it's guaranteed.
