> For my business' workloads, Threadripper 3 (same gen 2 Zen, same IO chiplet, etc) would likely be a much better fit (and competitive with Intel) if AMD sold it with the same kind of enterprisey guarantees they do for Epyc (ECC, etc).

Threadripper has official support for ECC. Well, "optional" based off of the motherboard's support: https://www.amd.com/en/chipsets/str40

And just picking a random board: https://www.gigabyte.com/Motherboard/TRX40-AORUS-XTREME-rev-... you'll see it listed:

"Support for ECC Un-buffered DIMM 1Rx8/2Rx8 memory modules"

That it must be un-buffered is an annoying market segmentation thing that limits your max RAM in practice, BUT you can at least get ECC up to 256GB with official support and RAM modules that actually exist.

Yep, I'm familiar with all that.

Yeah, it's that "optional" part that is problematic for ECC in particular. But don't let that be a distraction; there are plenty of other enterprisey features in Epyc that are not present in TR, including registered memory support.

Re: 256GB ECC UDIMM on an 8-socket TR board, that's 32GB a DIMM. I guess you can find 32 GB ECC UDIMMs now, but that's pretty recent and expensive.

Then don't make your example be ECC specifically. It's the only thing you listed, I wasn't "distracted" by it. And I also even commented on the lack of registered memory support, so I don't know why you're repeating that back to me?
