I'm just trying to get a definitive yes or no on whether or not the non-PRO Ryzen 5000 Series APUs (for socket AM4) support ECC memory. I know such support is dependent on the motherboard properly implementing this feature and the feature is not officially supported. I just want to know if it will work, given I'm running unbuffered ECC DDR4 RAM that is listed on a given motherboards QVL. This is no clear guidance on this issue. Asus's page on this topic is unclear:
https://www.asus.com/support/FAQ/1045186/
and this YouTube video from Wendell at Level1Techs implies that it >IS< supported, but not by every motherboard (comments start @8:45 mark):

In my particular case I am running a X570D4U-2L2T with the latest BIOS. Under Ubuntu 22.04 my Ryzen 7 3700X reports that the EDAC module is loaded, and dmi-decode -t memory spits out "Error correction: multi-bit ECC". But with my Ryzen 7 5700G (which runs fine otherwise) tells me "Error Correction: none" and "EDAC: no memory controller found". I suppose that gives me my answer right there, but I would like an official yes or no, so I know if it's just that this motherboard doesn't support these APUs for ECC operation, of if they are incapable of supporting ECC on ANY motherboard.
Thanks,
Steve Harper
