PC3-14400 isn't a number we typically see. What we tend to find is most companies promote their higher end PC3-16000 kits or the more standard overclocked modules, the PC3-12800 ones. What PC3-14400 kits offer us over something like a PC3-12800 kit is a bit more performance and a small jump in price while not going to the extreme that PC3-16000 kits tend to carry.
