Here is my setup:
CPU: AMD Ryzen 7 3700X
Motherboard: ASRock X470 TaiChi
GPU: Asus RTX 2070 Super Turbo 8GB Evo
Storage: Samsung 970 Pro 512GB M.2 (MZ-V7P512BW)
I’m looking for 32GB (2x16GB) ECC memory kit for ASrock x470 Taichi (non ultimate) with AMD Ryzen 7 3700X setup that will be running without problems.
*For Ryzen Series CPUs (Picasso and Raven Ridge), ECC is only supported with PRO CPUs.Please refer to below table for DDR4 UDIMM maximum frequency support.
Does anyone run ECC memory with that setup?
Can anyone recommend me suitable ECC memory kit?
They aren’t specifically listed in any of ASRock’s QVL reports for the motherboard, but reports from other X470 Taichi owners suggested they work just fine. My testing under Windows confirm these reports.
If I’m following this discussion correctly, it appears as though EDAC support for Zen 2 processors is in the process of of being accepted into the kernel. Which almost certainly means it doesn’t exist in the kernel I’m using. Could also explain why other users with Zen/Zen+ CPUs get full EDAC output from dmesg; support was added for those processors a while back.
Somewhat related: proper temperature reporting for Zen 2 won’t be added until 5.4
Looks like we were on the right track. This is from the current Fedora Rawhide live environment

Hopefully the formal release of 5.4 (and the uptake by various distributions) isn’t too far away. Now if only AMD hadn’t gimped the ability to intentionally corrupt memory, I might actually know if it was working properly.
