Consumer Ryzen requires unbuffered ECC RAM so most usual RAM options are not compatible.

SUPPORTS ECC RAM, but does not require it. You can use plain old RAM chips with it.

Grandparent's point, presumably, was that _buffered_ ECC RAM would not work. Which is definitely correct. I'm not sure if the sticks in question are buffered or not though.

Likely registered, not buffered - FBDIMMs fell out of favor some time ago. Technically still “buffered”, but only the control lines and it maintains electrical compatibility with UDIMMs.

Ah, thanks for that. I looked up the difference, I'll have to update my terminology.
