I disagree with the title, I don't think it says all Ryzen will support ECC.

>>4 x DIMM, Max. 64GB, DDR4 2666/2400/2133 MHz ECC and non-ECC, Non-ECC, Un-buffered Memory

That looks like a motherboard spec - because it is. And it supports Ryzen processors of various types. I read that as: One CPU supports "ECC and non-ECC", another CPU specifies "Non-ECC". At least that's how I read it. Otherwise there is no reason to put non-ECC in there twice.

The second one doesn't say Ryzen. I'm not up to date on AMD, but are you sure it's the same thing?

But it's a AM4 socket and is that only compatible with Ryzen atm?

AMD Ryzen™ Processors

4 x DIMM, Max. 64GB, DDR4 2666/2400/2133 MHz ECC and non-ECC, Non-ECC, Un-buffered Memory

AMD 7th Generation A-series/Athlon™ Processors

4 x DIMM, Max. 64GB, DDR4 2400/2133 MHz Non-ECC, Un-buffered Memory

That seems pretty clear to me that there's AM4 Ryzen and also there will be an AM4 A-series and an AM4 Athlon line. AMD has said repeatedly that AM4 is going to be the one socket for all their new chips from the server through to mobile. Look for the Opteron (or its replacement if the new server chips get a name change), the A series, the Athlon series, and Ryzen all to use the same socket but offer different memory and PCI configurations based on both the chipset and the CPU/APU.
