gigabyte X570S aorus master post code "FE"

[jakeabyte]

gigabyte X570S aorus master motherboard post code "FE". manual states "FE" is "FB-FF are reserved for future AMI error codes". though in multiple forums and other places, others with the same code have said it's a RAM seating/CPU cooler seating problem. i reseated my cooler, and reseated my RAM three times, the FE code still shows. i checked all my cables too. running most up to date BIOS (f5a), ran memtest86, no RAM errors, cleared CMOS, everything hardware related showing ok in device manager and BIOS, XMP enabled, showing advertised XMP speeds, but code still shows. not sure what to do.
