This is something that I've noticed is a problem with Asus. Intel and AMD come out with chipset updates every once in a while. I have a Ryzen 7 1800X CPU and an Asus ROG Crosshair VI Extreme motherboard. If I go to the Asus support page for my mobo the chipset driver there is out of date by months (February). It shouldn't be hard for Asus to keep these up to date considering how infrequently AMD/Intel release new chipsets.
In fact, Asus needs to do a better job updating their drivers in general. People like myself pay big bucks to get a top of the line motherboard. They should be supported with software and drivers for many years.
