I have a 3700x system (but running Windows) at home. Check with the motherboard vendor first? My board¹ has received three or four updates since I got it (which .. is an entirely different can of worms and doesn't exactly inspire confidence yet). At least they do seem to propagate things "quickly" I guess..
