That absolutely does mean it's enabled on all parts. They also don't validate the chips against FreeBSD - does that mean you can't run FreeBSD on their chips? Or do you think it would be ridiculous to expect them to test scenario's outside of the market they're targeting?

Do you have any idea the cost of running validation tests? I'm not the least bit concerned that they haven't "validated" the ECC functionality. It's enabled, they know it works, it's the same ECC they use on server class chips, and if someone found a bug I have no doubt they'd issue microcode to fix it.

I should have perhaps included the article which tried _enabling and using_ ECC on a Ryzen CPU+MB. [1]

Page 5 is perhaps the most important one, where it observes that neither Windows nor Linux appear to react by halting to a UE, and Windows can't quite figure out that ECC is enabled on the platform and parse the notifications it gets as such.

So, sure, I should concede that it is "enabled" on all parts, I was wrong. But that doesn't mean it should be trusted on any of them.

I guess we can agree to disagree. AMD implementing it, motherboard mfgs implementing it, but Windows not having an updated driver to handle it in all situations isn't on AMD. And it doesn't mean it's not there - it means that Windows is lagging slightly behind on a brand new platform. Something that's been fairly common with AMD for decades now. There's a reason the acronym Wintel became a thing.
