There are no Ryzen CPUs with ECC support. There are no Ryzen motherboards with ECC support. It may work. It may not work. It may seem like it is working but not actually work. It is 100% unsupported and unvalidated.
Server density.
As I understand it, though, some motherboards do allow for ECC with Ryzen...? Or is that no longer the case?
Many seems to buy ECC for the soft single-bit error recovery feature. Which Ryzen has shown to do fine even on non-official boards.
All Ryzens have ECC support. But, it is up to the motherboard OEM's to validate it. Some do, most don't. Is ECC 'there' yet? No, probably not. But please ignore the FUD, and make a decision with a clear mind.There are no Ryzen CPUs with ECC support. There are no Ryzen motherboards with ECC support. It may work. It may not work.

*Hands you blue Koolaide*No, ZERO Ryzen CPUs have ECC support. It is untested and unvalidated. It *MAY* work. It *MAY NOT* work. If it doesn't, AMD owes you nothing. It isn't even an optional feature, it is unsupported. They can perfectly well sell Ryzen's where ECC gives incorrect results either knowingly or unknowingly.
Lol, do you think the fact Ryzen works with ECC is just a happy coincidence? Like somebody slipped while designing the memory controller and it just happened to enable ECC? Of course Ryzen was designed to run ECC.There are no Ryzen CPUs with ECC support. There are no Ryzen motherboards with ECC support. It may work. It may not work.

Plus there are motherboards with ECC support, so you are just flat out wrong with both of your claims. And yes, these motherboard partners have validated ECC works in order to support it. I'm surprised you bother to post so much about a subject you obviously know nothing about...
All Ryzen CPUs support ECC, it’s just that motherboard vendors and AMD haven't gone through the server-level validation to ensure ECC works across the board. There are motherboard vendors who have ECC memory listed in their QVL, people have got it working in the latest Linux kernel patches. It has it's quirks but like every server-level feature on a consumer platform, you have to do your own tinkering to make it work.Care to list a Ryzen CPU that AMD supports ECC on? Care to list a Ryzen motherboard that the MB supports ECC on? There is a world of different between not disabling something and actually supporting something. Neither the motherboard vendors nor AMD will refund your CPU if ECC has an issue, neither of them supports it. It is a completely unsupported feature. There is no guarantee of functionality, no validation, we don't even know if they do functional test of ECC for Ryzen parts. Its basically the same thing as claiming that because your 1800x runs at 4.4 Ghz, that AMD supports 1800x at 4.4Ghz.

Why are you so hung up on ECC support?
People have tested it, it works.No, that means that none of them support ECC, they simply haven't had it explicitly disabled. For ECC to be supported, it would require AMD to actually support it by putting it as part of the specifications and guaranteeing the functionality, which they don't do.
So, by your definition, Intel DOES NOT SUPPORT overclocking, on 'K' SKU CPUs. It's just a happy coincidence; they just didn't lock the multiplier setting during testing, and any success overclocking those CPUs is totally incidental.Care to list a Ryzen CPU that AMD supports ECC on?

This means motherboard manufacturers will support ECC as they see fit. Need ECC for a personal project? Choose a motherboard with this feature enabled and tested, some manufacturers already did this as pointed in this thread. Need ECC for a business project? Choose a CPU with official ECC support, maybe Ryzen Pro will make that cut early next year.AMD said:ECC is not disabled. It works, but not validated for our consumer client platform. Validated means run it through server/workstation grade testing. For the first Ryzen processors, focused on the prosumer/gaming market, this feature is enabled and working but not validated by AMD. You should not have issues creating a whitebox homelab or NAS with ECC memory enabled.

Here, right from AMD themselves
Every Ryzen CPU supports this, AMD doesn't artificially gimp their stuff. It's up to the motherboard vendors to enable the feature on AM4. Look for motherboards that have the feature enabled and you're done. A first suggestion there at launch (that AMA was done on launch day) was the ASUS X370 Prime. I'm sure more vendors have implemented the feature by now.
Literally their own words don't say it is supported. Just that it *SHOULD* work. *SHOULD* is not *WILL*.
That just plainly isn't true. What AMD didn't do is work with motherboard manufacturers for months after final silicon (before release) to validate a feature that wasn't the target of the market. That's it. It is the same ECC that is TR, the same that is in EPYC. The idea that it isn't doing its job just because AMD didn't test for that Platform is just a terrible thought process.Basically, it sounds like AMD doesn't want people building servers with the Ryzen "consumer grade" CPU platform. They want you to wait for the server chips for that.
It's kind of disappointing, because workloads like VMWare ESXi would LOVE a CPU with tons of cores like Threadripper.

As for cores they gave us 6 cores for $200, 8 cores for $300, and will be giving us 16c cores for $850. All on a Desktop environment. All AMD cares about is people buying cores. But they aren't going to spend millions validate products that less than 1% are going to use and wasn't a target feature of the market. That doesn't mean people can't create cheap servers. Doesn't mean they can't run ECC, which does work, it just means that in a corporate setting AMD didn't give it their stamp of approval. Doesn't mean it doesn't work but if for any reason it doesn't work you can't blame AMD when you DB corrupts.
I think that the point that I'm trying to make is that no business in their right mind would use system with a Ryzen processor to run a production workload when AMD says that ECC memory isn't officially unsupported. The kind of people that would are the same ones that store their data on RAID-0 arrays... crazy people
Besides, VMWare ESXi doesn't even seem to run on system with a Ryzen CPU right now (it PSOD's on boot), so I wouldn't try to build a system for that purpose anyway.
You do if you are playing with things at home and having known working ECC is worth it not officially being supported if you don't have to buy a 5k-10k server to support it. I wouldn't approve of an actual business of more than 3 people trying it. But again the people trying Ryzen with ECC are specifically trying it because it works and since they are the ones that have to support the computer, don't need validation. Lack of Validation doesn't mean lack of working. If it was really a lack of working, then EPYC is screwed since it is the exact same memory controller.I think that the point that I'm trying to make is that no business in their right mind would use system with a Ryzen processor to run a production workload when AMD says that ECC memory isn't officially unsupported.
