I'm looking for input from anyone in the club who may be knowledgable, eyeballing, or has purchased a "workstation" system recently with ECC memory. (Note, ECC is imperative!) I don't need dual-socket, crazy speed, just something like a mid-range modern i7 with modern RAM, slots, etc. (i3 speeds won't cut it.) By "workstation" I mean it has to have at least one PCIe x16 (full 16 electrical) slot so it can have a good video card installed (and handle upgrades in the future). So some "servers" will qualify, although most do not have a true x16 slot (they'll say x16 but the small print will say x8 or x4 electrical), especially on the low end. I also need tower form factor, as rackmount will (unless 4U) be a pain to fit cards in, etc. Lastly, I really want a DIY setup where I buy the board, cpu, etc individually, though if a perfect premade system (i.e. Lenovo) exists that fits the bill I might consider it (must use no propreitary form factor parts, including mobo & PS). It's basically impossible since the discontinuation of the Intel D975 chipsets (nearly 10 years ago) to do Intel with ECC without buying a Xeon CPU. So I'm probably stuck buying a Xeon CPU and getting slower than i7 for double the price. Ugh. I'd really love to hear from the AMD nuts out there if there are any good AMD options, especially ones that are more enthusiast/desktop oriented rather than same-price-as-Xeon competitors. If I'm going to spend big bucks, I'll buy Intel: AMD needs to offer a compelling price advantage to pull me over. I still believe AMD could carve a niche for itself by offering desktop enthusiast chips / mobos with ECC at desktop, rather than server, prices. Maybe add $50 each to a mobo and cpu as the price premium. Not the 100% premium Intel wants just to get ECC. (I miss the old days when getting ECC was cheap/easy.) If AMD already has such a thing (I'm hoping!), great! I know I'm not the only one in the club interested in these answers. P.S. being a computer reseller, I don't need prices or store suggestions, I can just buy it all wholesale :-) It's the "this chipset plus that CPU" that I'm really looking for. Thanks!
Just for the record here (i.e., moral support for you, Trevor), I too have always been a strong believer in ECC.

Ah, so the original PC did simple parity checking only. And I believe that the PC AT did the same (definitely not less). However, very many PC clones right from the beginning never did even simple parity checking (and often had no DMA either, which the PC and PC AT had), and that set the trend toward no checking at all in the whole realm of consumer computers. By the time laptops came along, this was the norm, and only a few really high-end laptops ever did even simple parity checking (let alone ECC). By the way, ECC in the PC realm uses the same 9-bit RAM as for simple parity checking, but uses the parity bits over a whole block of bytes to do ECC. Doing ECC on a per byte basis would require 11-bit RAM.

Ya, pretty much everything was parity in 30-pin SIMM days, and even mahy/most 72-pin. So it was during/after the 486 days that parity disappeared. So the Pentium was the first to make it "difficult" to get ECC. This if from my personal experience/memory.

Off the top of your head, are these types of boards "normal" "desktop" prices plus a bit ($100-$200 CAD) or are they like Xeon "server class" board pricing ($250+)? Does AMD position these as enthusiast class or strictly business?

The AMD FX series is definitely "enthusiast" as are the AM3+ boards that support it. The AMD Opterons are the server-class models. The FX series definitely supports ECC; I use them with ECC with no trouble. The FX-9590 (8 cores) is the top of the line (unlocked so you can play with clock multipliers), but is rated to run at 4.7 GHz with Turbo mode to 5.0 GHz. Priced around $300. Most AM3+ boards are $100-$200 with a few outliers. Though if you wait for the Ryzen series, performance will be even better.

I spent some time reading more about the upcoming Ryzen stuff and the consensus regarding ECC support on "desktop" and "power user" boards is that nobody knows. Most people think there will be ECC options because some previous gen boards did, but no company has committed to saying the support will be in Ryzen. It does appear that ECC is guaranteed if you use a "server" or "workstation" board (i.e. probably over $200, or without x16 slot), but then that puts Ryzen in the same boat as Xeon and for the same money I'll just buy a Xeon. So I guess we can hope, and wait and see. It's like the world is a big conspiracy to keep ECC out of "affordable" boards, when (from my reading and MUUG discussions) ECC on the desktop is desired by tons of people. You'd think there'd be a niche in there somewhere if some enterprising company can realize it...
Now that Ryzen has been officially released, I've found some answers. Ryzen does support ECC. The current batch of models does. However, AMD has not "certified" it to work in the same way they test their server models (of previous gens). Future Zen-architecture models for the server market will be "certified" by AMD to work with ECC. This is no different from past architectures, meaning that like in the past motherboard manufacturers will produce AM4 boards which fully support ECC (at a reasonable price) and are "certified" to work with ECC *by the motherboard manfacturer*. So, I'm just going to wait a few months for the dust to settle then buy a Ryzen with an ECC-capable motherboard. Kevin On Tue, Feb 14, 2017 at 1:49 AM, Trevor Cordes <trevor@tecnopolis.ca> wrote:

Do you know offhand which mobo makers usually "certify" (or at least make very clear) their support of ECC? I know in the past I've had issues with chipsets/cpus that support ECC and boards that *purport* to, but really didn't. Also, do you know if these "enthusiast" AMD chipsets/chips usually get support in the edac package (which can query the chipset and report ECC error counts)? It seems to cover only about 75% of the ECC chipsets/chips out there, even ones that have been around a while. (It takes someone who cares to write in support for it.)
So, I'm just going to wait a few months for the dust to settle then buy a Ryzen with an ECC-capable motherboard.
Sounds great, I'll keep my eyes out (and you keep us posted too!). Maybe when the time comes I'll price out a Xeon vs Ryzen comparison and post it.
Long ago, when I was doing hardware, the Asus motherboards that properly supported ECC were clearly identified by Asus as such. Hartmut W Sager - Tel +1-204-339-8331, +1-204-515-1701, +1-204-515-1700, +1-810-471-4600 On 4 March 2017 at 16:56, Trevor Cordes <trevor@tecnopolis.ca> wrote:
