Doesn't look like the 3000G supports it. https://en.wikichip.org/wiki/amd/athlon/3000g

AFAIK, all ryzen cpus UNofficial support ECC, its up to the motherboard IIRC.

No, the 3XXXG series do not support ECC; which simply do not work. This is because the iGPU doesn't support ECC RAM.

What, how? The only part of the chip that touches the ECC bytes should be the memory controller itself. The reads and writes going across the internal fabric should be exactly the same.

Also the PRO versions support ECC and seem to have the same iGPU.
