You mean server chips. The server Atoms also support ECC. For eg. https://ark.intel.com/products/97927/Intel-Atom-Processor-C3...

If I'm not mistaken there are a few Pentiums and i3 chips that support ECC. For example the G4560.

Even AMD think of it as such. Ryzen doesn't have it disabled on the desktop, but AMD haven't validated it either.

Didn't AMD employees confirm it a few times on the web already ?

ECC is working with AMD if the motherboard supports it, but you can't always be sure that the motherboard does support it correctly. You need to rely on user reports/what the motherboard producer promises, instead of it being a default feature that always works.

Still a lot more than what Intel offers in that space.

Thanks

I didn't say ECC doesn't work. It is enabled on Ryzen. But it's not something AMD go to the effort of validating to make sure it works properly and it doesn't get support. It's left in there as a footnote for enthusiasts.
