> That's as opposed to "validated" ECC support in, say, AMD's Threadripper platform. In that case, if a company builds and markets a motherboard as compatible with Threadripper, and it lacks ECC support, they can expect to receive a nasty letter from AMD's legal team.

Are you sure about that? I'm only asking because the System76 Threadripper Thelio[0] doesn't support ECC (according to the response I received from their support people). Their response was actually that "Threadripper and our motherboard do not offer ECC" (TR obviously does support it though), but is it the case that they're actually contractually obligated to support ECC?

The Thelio Major uses a Gigabyte X399 Designare EX motherboard, which has ECC DRAM support. System76 may not offer or support ECC DRAM as an option, but you can add it yourself if you're so inclined.

Okay, that's actually great to know. Thanks!

It's EPYC that has ECC. Threadripper is for enthusiasts, not the professional market.

I'm running ECC memory on my R1700X... I'm fairly sure TR also has ECC memory. In fact, all of AMDs offerings except for APUs have ECC enabled, but AMD does not force motherboard manufacturers to implement it.

Threadripper and many Ryzen chips support ECC as well, and the professional market can use either and still be professionals.

EPYC has registered memory. While ECC is (traditionally) more common in RDIMMs, it's also available in UDIMMs.
