ASRock Rack EPYCD8-2T Makes For A Great Linux/BSD EPYC Workstation - 7-Way OS AMD 7351P Benchmarks

ECC memory, mainly. AFAIK not officially supported on Ryzen or TR.

Both CPU platforms support ECC, but, not all motherboards do.

The fact they have a 7000 series 'big' EPYC for large servers, and a 3000 series 'small' EPYC for embedded, certainly leaves open the possibility of future 5000 series 'medium' models, with desktop/workstation oriented 65w and 95w TDP's.

I don't disagree there could be 65W parts; in fact I find it likely. What I'm disagreeing with is whether they're going to make 8-core Epycs in the future. AMD is really pushing multi-core pretty hard.

Ok. But as I said earlier, AMD just this month, Feb 2019, released a bunch of new EPYC 3000 series chips that include a new 8c model, and an 4c/8t model, and a 4c/4t model. This active development of new 8 core and 4 core EPYC models makes your prediction appear unfounded.

I'm still not sure if ECC for TR is really a gamble. I've looked through all of the 15 available TR4 boards and EVERY board has support for ECC modules mentioned in the specifications table. Listed and tested in the QVL is a different story, but in general every vendor states support for ECC on the X399 chipset. Do you have an example where ECC isn't working on any specific X399 board?

AM4 and Ryzen is really a different story, to be fair.

Someone needs to use this board + 10 Vega VII + a add-in board with at least 8 USB controllers to build 1 PC 40 Linux gamer monster.
DRM Lease is fun. Only problem is that radeonsi does not work. But Vulkan via RADV does.

If that's true, it sounds like the X399 board ECC support has improved considerably. As the links I posted illustrate, ECC support on X399 boards was at one time, spotty and inconsistent, leading to plenty of consumer confusion. Whether through firmware updates, or just better vendor support, it sounds like over time the situation has improved.

Sounds reasonable. Digging at bit deeper, at least Gigabyte, MSI and ASRock have actually tested and qualified ECC modules. Asus has many many modules tested but you can't see if it's ECC or not without looking for specific part numbers of ecc modules.

If I would have to buy a new TR4 board, I would go for ASRock (again) or would try MSI. Gigabyte is just disappointing on TR4. The bios support is more or less non-existent and I really regret taking the gigabyte road on TR4.

if only that were AM4.... I have an old X99 that spews AER errors like a mad dog, can't wait till a consumer AMD processor can handle 7 slots at least PCIEx8 in length each

Looks like a good board, but where did you buy it? The availability of this part appears to be negligible.

ECC on TR is official. https://www.amd.com/en/products/ryzen-threadripper


Quad-Channel DDR4 ECC Memory Support
With the most memory channels you can get on desktop, the Ryzen™ Threadripper™ processor can support Workstation Standard DDR4 ECC (Error Correcting Mode) Memory to keep you tight, tuned and perfectly in sync.

And most TR boards I know do support ECC.
