Hi dehinson and Welcome to ROG
The dreaded FF qcode can be difficult to determine but usually means a fault has been found.
Should this error stop code persist, you will have to bench test outside your case, however you can initially try the following.
Ensure your Bios is up to date. Use the flashback port on your IO panel.
Ensurer both 8pin and 4pin sockets on the MB are populated.
Make sure your DIMMs are compatible and listed on the ASUS QVL.
Try installing just 1 Dimm in the A2 socket to initially post with.
Try to post with peripherals, GPU and drives disconnected, to see if QCode led advances or shows a different error.
