All I want is a single socket CPU and a motherboard that supports ECC/isn't total garbage. AMD has said it's on the motherboard manufacturers, and I haven't been able to get a straight answer as to whether ECC works as it should on motherboards that support Ryzen - https://www.reddit.com/r/Amd/comments/80wpd1/ryzen_2_ecc_sup...

Here's a list of Ryzen motherboards that people have tried and succeeded in using ECC with: http://www.overclock.net/forum/11-amd-motherboards/1629642-r...

Additionally, you can check the QVL for each motherboard, and then test it by hand.

Thanks!

*Edit - $750 is a lot for the cheapest threadripper + mobo. I'd be happy with 48 PCI-E lanes around $400 (CPU+Mobo).

You can get a non-Threadripper Ryzen CPU+mobo with ECC support for far less than $400. Obviously it lacks the PCIe lanes of the TR setup. These are both ridiculously cheaper than you could get similar capability for before Ryzen launched. If you really want 48 PCIe lanes for $400 you can get a used Xeon X99 setup for that much.

$750 for "workststation" class is really inexpensive.

$400 is really cheap even by consumer standards.

Really? I don't need high clock speeds, I'm looking for a reasonable (48) number of PCI-E lanes and ECC support.

That's called workstation class. Most consumers need barely 24.

To me that overclock post was just further demonstration of the sad state of affairs re. ECC

Ryzen Threadripper and the TR4 socket are advertised with ECC support on the AMD website¹², in contrast to regular Ryzen/AM4. This may mean that all motherboards support it. I can't be sure, however, ECC seems to work fine on ASRock X399 Taichi.

Why not buy a server board? Edit: Its on the motherboard manufacturers not really the chip makers.

The C236 chipset is old as hell (2015) - they're holding back on adding PCI-E lanes, because they can.

My hope is that Ryzen 2 shakes things up / Xeon 'Entry' offers a decent board.

The Xeon D chips are a total frigging racket.

Totally agree regarding Xeon D statement
