I have been so frustrated with my MSI X570-a PO that I have now removed it and I have gone back to my X470 Gaming Plus board.
The X470 works properly but I bought the X570 for performance reasons. I am now of mind to pester MSI to buy the board back as defective.
My RX 480 works on the X470 fine, not on the X570
