Ryzen's apparently have ECC support but I went to have a look at a motherboard to suit and the only ECC RAM it takes is unregistered which unlike the usual registered ECC found in servers is uncommon and there's not a lot of choice available and furthermore is more expensive than both standard RAM and registered ECC. Question 1. Are there any Ryzen motherboards that take registered ECC, I suspect the answer to this question is no. Question 2. Is there anyone here that uses even unregisterd ECC in a large way e.g. for content creation or VM's where they actually do have a need for ECC? Question 3. Does the ECC function actually work or is it just the case that it accepts unregistered ECC and works in non-ECC mode?
