I read that all these new AMD CPUs support ECC, but it’s been hard finding verification. Can any one recommended a motherboard that both supports and uses ECC RAM with this new CPU?
It seems like ECC support is pretty widespread, I know for a fact that my Asus Prime X570-PRO has an option for ECC memory in the bios and it's a midrange board. Might depend on the board manufacturer to enable it. Asus seems to have it in most if not all of their boards.
