AMD Ryzen 7 1700 (14nm Zen)

I really don't think you understand the position of Ryzen 7 CPUs. They're high margin parts. They're intended for prosumers, not gamers. Watch the launch presentation - or any of AMD's info presentations about Ryzen 7 - and you'll see that they make a big thing of the app performance first - gaming is almost an afterthought.

And yet, there is *NO* ECC-enabled Ryzen motherboard on the horizon (but plenty of "gaming" motherboards) and ECC support in Ryzen is almost mentioned as an afterthought, if at all.

Yeah, I know. I should shut up about ECC, but it's somewhat of an obsession with me.

Oh, and sorry for taking your reply a bit out of context. It just fit so well with my pet peeve that I felt compelled to do it.

The Asrock taichi has ECC support. Naples has ECC support but the consumer version has the support but no official validation as far as i am aware, if you have the Asrock board you shouldn't have a problel

Are you absolutely sure about that? There's a single blurb about ECC both in the specs and in the manual for the TaiChi. There's no mention of a BIOS option or anything and the whole thing seems a bit vague. I've checked the specs and manuals for most X370 boards and have pretty much come up short.

We discussed ECC in the Zen chipchat thread.
Mainly referring to this thread over on AT
https://forums.anandtech.com/threads...t-and.2500613/
which in turn referred to someone on HardwareLuxx.de who had managed to force an ECC error

The HardwareLuxx guy used an Asus Prime X370, but apparently the ASRock TaiChi has ECC scrub options in the BIOS.

The HardwareLuxx link was very informative, as was the Anandtech one, which correctly brings up the following requirement for ECC:

If board supports ECC (if all wires for 72bit memory channel are physically present) and BIOS supports it, then you should be able to see configuration in UEFI/BIOS once you slot-it ECC UDIMMs (at least auto/off as on "basic" Asus boards)

At lot of people seem to think it's merely a BIOS/UEFI setting if the MMU of the processor supports it, but that is far from true, which is why I usually take those vague "ECC supported" statements in the specs with a huge grain of salt.

I have FM2 socket boards that merely tolerate ECC ram but offer no protection. Sounds like the IMC on the chip can do ECC, but AMD left out the extra data traces on the consumer socket.

Worse still, my Wife's PC had an AM3+ ASUS board with ECC ram but swapping to an Asrock when the Asus failed the ECC ram is now just run as normal.

I guess most people are cheapskate and/or don't run home servers as ECC doesn't seem to get talked about much.

Well, it *seems* as if it's a question of having the necessary traces on the motherboard and having an option to enable ECC on the new Ryzen systems. As I understand it both the CPU and the socket (AM4) are capable of using ECC.

Seems like a nice upgrade for my i7-2600k ... oh wait.. DDR4.
Ain't gonna throw the 32GB DDR3 I already have and paid a fortune for out the window.

At some point you have to. Perhaps right now the DDR3 has some second hand value so you could sell it before it is worth as little as DDR2.

It seems to me, u r doing a piece on overclocking, but at an unambitious 2666MHz clocked ram?

3,000 MHz seems common even in these early days.

Ryzen I hear, is v affected by mem clock, as the northbridge is clocked to .5 memory speed.

Just to clarify, the on-die fabric is clocked *at* memory clock, not half. People confuse clocks and transfer rate with DDR, where as its name implies, has transfer rate at twice the clock speed.

E.g. 2400 'MHz' DDR4 is actually 2400 MT/s, and its clock is 1200MHz.
