ASUS Expedition motherboards are made for non-stop action, engineered with non-stop durability to prevent damage from moisture, corrosion and overvoltages -- for immense longevity. Even the memory is locked down for superior security. Asus even tests them to the limits, with 144 hour of diskless-system tests and extensive checks for compatibility with top games and over 100 gaming peripherals. And for the ultimate audio, Expedition motherboards have Crystal Sound 2 to provide exhilarating non-stop gaming performance -- and the best stability, reliability, and value for you!
