Yes. Eg. https://www.asrock.com/MB/AMD/X470%20Taichi/index.asp#CPU
Seems like a good question for this thread.

I tried to merge it but failed.

The effort is appreciated nonetheless. I am also interested in the answer though, but I can’t imagine Zen+ going without ECC considering Zen’s origins and usage in Epyc as well.
All I can say right now is BEEEEEEP

This.
Not only what the system reports but also at what point does the chip begin to throttle.
Is that one beep or multiple beeps?

What are the IOMMU groupings like on the x470 boards?
What is the Linux support like?
Does StoreMI work with Linux?
Those are the things i’m wanting to know.
ready to pull the trigger on a 2700x in the next couple of weeks with a view to replacing my E3-1231v3 haswell box. I definitely want to run looking-glass.
Taken from here:
I second this questions about ECC memory. Everything else about the product seems to be an open book already.
Will it blend?
I’m a little more interested in chipset differences rly.

That’s the big one, I agree.
If it’s like previous AMD CPUs then ECC compatibility will be there on the CPUs, it’s up to the motherboard manufacturers to implement the feature however.
IIRC it’s like that on Ryzen, Bulldozer, Phenom II, and I think before were like that. Unregistered/Unbuffered only either way.

Try running kill-ryzen.sh on it for shits and giggles

I don’t believe AMD have built a CPU that DOES NOT support ECC memory in over a decade. Even my lowly Turion micro-server does.
But you don’t know. That is why the question is valid. 
Oh for sure.
But just saying, it would be very much out of character for AMD to do so. Especially given its a minor bump of the Ryzen platform, which does.
I think more interesting will be which motherboards support it.
Got something. From the spec site of the Taichi Ultimate:
I am guessing there is a copy & paste oversight and it should read:
For Ryzen Series CPUs (Raven Ridge / Pinnacle Ridge), ECC is only supported with PRO CPUs.
So that would mean proper support only with Ryzen Pro. (at least official)
APUs have no support for ECC of course.
I doubt that, as we know ECC is supported for Summit Ridge (1000-series) already and that chart lists them correctly. Most reasonable assumption is that this motherboard supports ECC on both Pinnacle and Summit Ridge but not Raven Ridge.
Furthermore we know that Raven Ridge does unofficially work with ECC, but it needs motherboard support.
Well certain motherboards will support ECC.
But of course Ryzen and Ryzen + are platforms geared towards mainstream desktop use and gamers,
on which ECC doesnt really play much of a role.
Its nice that it sorta kinda works but yeah.
Motherboard manufacturers probablly wont pay too much attention to it.
People that really have a need for ECC memory support,
generally dont look at mainstream type hardware,
but rather HEDT and or workstation enterprise hardware stuff.
Its nice that ECC support is sorta kinda there but yeah…
99.9% of the users wont need it or even bother about it.
