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.

If the system is working properly, it may just be a place holder for no issue that Gigabyte uses. I'd check your event viewer logs, make sure nothing is going on like WHEA_Uncorrectables. If everything looks good, ignore it, or disable it in the BIOS after POST. Make sure the debug LED's are clear. I've seen manufacturers use AO, or FF as debug codes for no issue. Additionally, important to remember that the debug codes are for POST, after the system does POST, the LED is used for op codes by the OS. My guess is the FE being displayed is just a bug and there is no issue. Likely a BIOS bug, updating the BIOS may clear it.
just checked event viewer "hardware events", and there are no events, so i'm guessing the hardware is ok. let me know. also, will try to update BIOS, though it's running the latest version. i'll just overwrite it again. but now i need to buy another flash drive, it's not working haha.
nevermind, just checked system error logs, i'm guessing some of these matter, or are causing the FE code? they are:
i think the only one that matters is the first one in the list, since it's hardware.
sorry for me being confused again, that first one has nothing to do with C:, i was trying to fix a USB drive. so nix my whole reply above haha. will get another flash drive and just flash overwrite my existing BIOS.
The latest BIOS is F37b is a beta. You might want to rollback to F36 instead. It's probably just a bug with the beta BIOS. OS is reporting an op code it can't interpret.
i have the x570s aorus master, not the x570 aorus master. current is F5a.
another thing i could be thinking is, my ram kit isn't in the QVL list, but others are running it, same board, and says it's fine, and it's even posting the XMP profile as stable at the advertised XMP profile.
Might try F4 in that case. Doesn't indicate a memory problem. If the memory were unstable, you'd be seeing BSOD's. I really think this is a bug with the beta BIOS interpreting an op code incorrectly.
