The Ryzen "ThreadRipper"... 16 cores of awesome

Server density.

As I understand it, though, some motherboards do allow for ECC with Ryzen...? Or is that no longer the case?

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.

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.

No, actually it hasn't. It is an unsupported and unvalidated feature that no one has shown to be actually working. For all you know, every time it is reporting an error correction, it is flipping more bits to the incorrect value. Unless it is an officially supported feature with validation and verification and post-si testing, it doesn't actually do anything because you don't know that it does.

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.

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.

Looks like it's supported and working just fine.

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.
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...

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.

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.

Why are you so hung up on ECC support?

 

[richaron]

ASUS PRIME X370-PRO was the motherboard I was looking at. I'll admit there aren't heaps of motherboards with both ECC support and DisplayPort. From Spec's relating to "AMD Ryzen™ Processors":
"4 x DIMM, Max. 64GB, DDR4 3200(O.C.)/2933(O.C.)/2666/2400/2133 MHz ECC and non-ECC, Un-buffered Memory".

Ryzen was designed to run ECC, AMD doesn't support it, but ASUS has validated and support their motherboards running ECC with Ryzen CPUs.

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.

People have tested it, it works.

You can do all the mental gymnastics to elaborate on what "support" means in this context, but the thing is people have got it to work as intended.

AMD has not made rigid definitions about what "support" means because it is up to the motherboard vendor to implement it.

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.

 

[coercitiv]

Can we end this ECC support debate? AMD has been crystal clear on this subject.

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.

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.

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.

Of course they don't. Overclocking is very much mileage may vary. They don't officially support running any processor outside of the specifications. Get a 7700k that won't overclock? Not Intel's problem. Same thing with Ryzen and ECC. It may work. It may not work. It may appear to work but not actually work. Its not a supported feature and the functionality isn't required to meet the specifications that AMD agrees to meet.

Is it in the specifications? If something goes wrong will AMD fix it? If there is a bug are they responsible? No. It is quite literally the same as saying the processor is unlocked and you can try to clock it at whatever frequency you want at whatever voltage you want, but if your particular CPU will work at a given frequency/voltage is not certain nor is it certain that you'll even be able to tell that it isn't working.

Literally their own words don't say it is supported. Just that it *SHOULD* work. *SHOULD* is not *WILL*.

Sometimes it's better to admit you are wrong and go to the next subject, it's obvious to every one else....

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.

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.

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.

Man, the dissonance is strong in here. Ryzen supports ECC, as demonstrated in this thread, from direct comments from AMD officials and spec sheets from motherboard manufacturers.

Seems to be devastating to Intel fanatics.

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.

People do unexpected things with their hardware. Always have and always will (unless manufactures disable features). Since AMD didn't disable this feature in Ryzen, some will use it and expect it to work.

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.
