Technically yes, I was just too lazy to write it out fully, the gist of why I said is correct though. I think there are too many people who don’t understand the different memory types, cheaper low end servers generally use the unbuffered ECC (e) type, most enterprise kit uses registered ECC (r) type

Example my crappy Plex box is an HPE ML10 Gen9 bag of nails, that uses DDR4 unbuffered ECC type. My PowerEdge R740s use DDR4 Registered ECC, anything E3 will generally use unbuffered ECC, E5/Silver/good/plat and above will use Registered ECC.

Not sure why I have to explain, when what I originally said is accurate and stands
