The B550 chipset is for AM4/DDR4 boards. For newer AM5/DDR5 motherboards, the ECC support is a lot less clear. As in: several motherboard vendors have claimed ECC support in the past, but no longer do, without publicly stating a reason. Also, some boards do list ECC memory modules in their QVL, but do not claim ECC support; whether this means that the board supports ECC or only that the memory module functions without ECC, nobody knows.
