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…

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.

That's awesome, I think this is the perfect CPU for my next ZFS NAS. If you try to find ECC support in Intel's lineup, it's hard to find much. Either the low end Pentium, or the high end Xeon ($$$).

Nonsense. Xeon e3 all have ECC AFAIK; the whole line. My old low end Xeon e3-1225 has it, and the latest e3-1225 v5 has it too. It's a $200 chip and is eminently suited for ZFS NAS (that's what mine is doing) - as well as desktop.

Yes, I still remember what a PITA it was to identify a motherboard that both supported ECC and allowed enabling it in the BIOS for my last AMD build (circa 2007). I still remember reading about boards that offered "ECC support", but had no way to enable it in the BIOS, change the scrubbing time, etc. And how relieved I was that whatever I wound up with did indeed have full ECC support. Then again, buying Xeon boards…

There are plenty of SuperMicro desktop boards that include sound (and support ECC).

Yes, I'm typing this from one (X10SRA) now. But there was some drawback to getting sound in ~2011. And even when I built this one, I wasn't really happy with the selection.

A poor selection and higher prices is a consequence of fragmenting the market and making workstations with ECC a fairly rare thing.

I wonder if they have. I don't know if this is water-cooler gossip, but I have heard they are going to have another release in 6-8 months and Kaby lake is simply a placeholder. I wonder if they are far ahead enough to drop something that beats Ryzen on every metric including price. Either way, that would push it up quick.

Evidently, while Cannonlake (the 10nm next gen chips for low-power SKUs) got punted to 2018 [0], Coffee Lake (the 14nm next gen chips for desktops) are still on for 2017 [1].

Didn't Intel release new CPUs last month? they'll be running out of lakes soon to overcharge us for 10% improvements.

That's demonstrably not true, AMD has supported ECC more or less across the board since the Athlon64. Enterprises may be professional cost cutters, but before that they're professional ass coverers, otherwise Oracle would have died 20 years ago.

AMD does not support ECC on consumer platforms after AM3+. Socket FM1 through FM2+ are all incapable of supporting ECC. For socket AM1 there are reports that it may be ECC capable, however no actual products exist that implement this support.

The socket can't support it, the processor most certainly can since the memory controller is built-in.

Desktop Kaby Lake launched last month, portable Kaby Lake started shipping to OEMs Q2 2016.

Intel used to try for a tick or tock every year - so Sandy Bridge in 2011, IVB in 2012, Haswell in 2013, then Broadwell was incredibly late except for a handful of SKUs in 2014, Skylake in 2015, Kaby Lake (mobile) in 2016...

Really the problem is that Intel ends up having these staggered releases, probably to address limited yield on their new processes and the most impact/value (since they've been so focused on improved work per watt, and mobile cares about that for a lot more than just heat dissipation reasons...)

ECC support in CPU is just a half of success. Now somebody have to convince motherboard manufacturers to enable it. It was the same thing with previous AMD CPUs. They all had ECC support but there was virtually no motherboards that would support it.

Yes, I still remember what a PITA it was to identify a motherboard that both supported ECC and allowed enabling it in the BIOS for my last AMD build (circa 2007). I still remember reading about boards that offered "ECC support", but had no way to enable it in the BIOS, change the scrubbing time, etc. And how relieved I was that whatever I wound up with did indeed have full ECC support.

Asus was the most forth-coming about that. If they mentioned ECC support on a motherboard's specifications page, then it supported ECC and it couldbe enabled, etc. If they didn't, then there was no ECC support. Other manufacturers were far less informative about that. Maybe because it was rare for them to support ECC. E.g. I think that none of Gigabyte AMD motherboards had ECC.

To be fair, that "ECC and non-ECC, Non-ECC" reads like they were still editing the page and hadn't made up their minds yet if the motherboard supported ECC. In other words, they were deciding between "ECC and non-ECC" and "Non-EC".

64GB is also the limit of Intels desktop i7 processors. I don't think Ryzen is intended as server processors, so 64GB should cover the target market very well.

Nope. X99 i7s support 128GB and quad channel memory. Most of X99 boards come with 8 slots as well. However the setup is way over-priced, so I'm going to preorder Ryzen on day 1 if available. It just seems like phenomenal value.

Sandy-E to Haswell-E i7's do not officially support 128gb, though there have been reports of it working.

Broadwell-E i7's now officially support 128gb.

All the Xeon equivalents (e5-1650/60,80, etc) support 256-768gb depending on the model, if paired with a consumer board that limit is usually 64-128gb.
