In this round-up we primarily looked at the overclocking potential, and this differs per module. It could very well be that a certain brand RAM module overclocked very well in our test, but that when you buy one from the store it doesn't perform the same, perhaps better or perhaps worse. It comes with the territory.
That said, we are impressed by the Kingston kit. It is the most affordable DDR3-2133 kit that we know of, and with the exception of a more expensive CL9 kit also the most overclockable. Win-win in other words, and therefore this kit earns the Hardware.Info Silver Award.
