The Gigabyte X470 Ultra Gaming lasted a total of two weeks. The X570 ASUS was DOA out of the box. My Gigabyte Z370's have been going strong for about 2 years (the one with the 8600 and the 9600 is probably only a year and a helf). I have had an Asrock board last me 5 years before. My MSI B350 is still going strong and I purchased a 1700 for it right when the Ryzen processors were introduced. I have an X300 (unknown chipset for a midget system) ASROCK A300 with an AMD 3400G in it right now as well. That's 6 months to a year old and I have changed the processor on it 3 times. So, I have been flexing the hell out of the motherboard. I suppose it really comes down to how much love the motherboards got at the factory. Sounds kind of odd, however, almost any piece of hardware can fail.
