Processors

[eagle12426]

Hello to everyone, I am new to this AMD site, well I am new to any AMD site even though I have a PC with a AMD CPU. My question is what processors, besides the RYZEN PRO, will support ECC memory. I am going to be building my own. I already have a motherboard in mind, ASUS WS X570 for the build. I also have a Thermaltake Core X71 Tempered Glass case for everything to go into it. I am getting parts a little bit at a time. Thanks in advance for your help

All Ryzen chips support ECC memory.  But not all AM4 motherboards do.  If by "WS X570" you mean the Pro WS X570-ACE, then the board does support ECC.

I should add, it's only unbuffered ECC that's supported.  Registered ECC is only supported on EPYC and Threadripper Pro processors.

Thanny,

Thank you for your input. All I have to do now is decide on which RYZEN to get, along with the mobo. I'm not 100% sure on getting the Pro WS X570-ACE but I do know, which even board I do get, I want at least two GPU'S to go with the board and the CPU. YES it will be one heck of a build. If you have ANY suggestions about the build, by all means suggest them. Thank you again in advance and anyone that has any suggestions. Every little bit helps even though it's ultimately my decision on what to put into the build.

Thanks again  Eagle12426

FWIW:  

Running unbuffered Micron/Crucial w/2 channels dual rank 32GB sticks of ECC memory on a x570 Taichi w/5600x and memory @ 3600 with no problems.  I think I bumped the voltage up a 0.1v or so to give margin.  ECC seems to work ok, but haven't tested the poison features of the MB yet.  It does recognize and unlock the ECC features on the BIOS though.

thanks for the input

Thanny,  I just checked on the ECC memory that you had said all RYZEN chips support unbuffered memory. Unless I read it wrong. It had indicated that it does not. If you could send to me by email what AMD chips support ECC memory that would be GREAT!! thanks again.

It's as I said.  All Ryzen chips support ECC memory.  That means the memory controller on the chips (on the same die as compute with Zen and Zen+, on the I/O die with Zen 2 and Zen 3) support ECC, and that functionality is not artificially disabled with any models.

Whether or not ECC functionality is enabled depends on the BIOS.  On a motherboard which doesn't support ECC, unbuffered ECC memory will act as normal unbuffered memory, without ECC.  If the BIOS supports ECC properly, then you get the expected ECC functionality, which is correction of single-bit memory errors, and detection of multi-bit memory errors.

As near as I can tell, all Threadripper boards support ECC properly.  When it comes to AM4, the picture is muddier.  Pretty much all of them will support unbuffered ECC DIMMs, but not all of them will actually enable ECC functionality.  You need to look at the motherboard documentation itself to figure out which support ECC properly.  In all cases, if ECC doesn't work, it's the motherboard that is the limiting factor.

Oh OK,  I misunderstood or was mistaken by what you ha said. Now I understand what you said. Again my mistake. Thanks again.

Is ECC memory 'REALLY' needed? It's bloody expensive and a pain to get / find from what I have heard.

I believe Intel is mostly responsible for that..?

As for support. Most if not all the X570 Chipset boards should support it. Just check 'As you should anyway to ensure RAM support / compatibility in whatever short listed motherboards models you're leaning towards..'

** Also, as far as dual GPU's.. Personally I really wouldn't bother unless there's some weird or high end rendering or similar work machine. If just for personal use / high end gaming, save some $$'s and just get one high end GPU and save the money to upgrade to a new GPU 10 - 12 months down the road (Possibly sell off the old one too to regain some $$'s) A lot of games don't really SLI or benefit that greatly from having two GPU's and if you're talking high end. 5 to 6K (AUD) on just Graphics cards that will probably be a $600 odd card in 12 months or so, seems a little excessive in my eyes.. But again, if needed for a particular purpose or you have a phat wallet then hey, why not I guess..?

From what I've seen and the current GPU Wars that are only going to grow with intensity (Especially with AMD Chips in both the new consoles) I feel there's going to be some interesting releases / pricing on GPU's over the next 12 - 18 months.

Personally, I have no experience with this motherboard but the official QVL list includes Kingston's 16GB DDR4 RDIMM. It appears the motherboard works with both UDIMM and RDIMM. If you are building your own pc then I think UDIMM Memory from Crucial and Samsung are your best bet.
