It shouldn't be a problem to have the Chip-set from 2013 as long as everything works fine. Asus last Chipset package was for Windows 8.1 from 2013 which should work in Windows 10. There has been no other updates. Your Motherboard is EOL (End Of Line) and not supported anymore with updates from Asus.
There is a bug when trying to install AMD Chip-set on a motherboard with a NON-AMD GPU card installed. Were you able to install the Asus AMD Chip-set or did you get the same error? Seems like AMD doesn't support Motherboards with FM sockets or earlier with Chip-sets
