The table below shows list of Ryzen processors that support memory modules with ECC functions, along with their official names, and if they are supported by B550 and/or X570 chipsets. Please note that when it comes to APUs (Ryzen 3000/4000 G-series), only PRO processors (e.g. Ryzen 3 PRO 3200G) will support ECC memory.       If the problem still cannot be fixed, please contact ASUS Product Support
