[Correction] ASRock X470D4U2-2T

This motherboard requires ECC RAM, however is listed as incompatible with ECC RAM, therefore making it impossible to choose RAM

Supports 4x DDR4 ECC and non-ECC UDIMM, max. 128 GB

ECC is not required.

We do not show ECC memory as compatible with Ryzen consumer chipsets as it is not validated or tested by AMD and may not work correctly even if recognized.

You're right about ECC support on consumer Ryzen motherboards, it's done on a best effort basis by the motherboard manufacturer even thought all Ryzen CPUs technically support it, and YMMV. However this is made by ASRock Rack, their enterprise/workstation grade server brand. Although the X470D4U and X470D4U2-2T both use Ryzen X470 "consumer" chipsets, they have been explicitly designed and validated with ECC memory in mind. It's not mandatory, and non-ECC memory is not incompatible as @Ookgluk32 suggested in their original post.

I have several deployed systems built on this platform with ECC memory from ASRock Rack's QVL and it works perfectly, and I haven't seen any of the symptoms or issues in HardwareCanucks' thorough article in my testing.

As this is the first in (hopefully) a long line of future Ryzen-based server motherboards, can PCPartPicker please review their policy on ECC support and memory compatibility for server components?
