In drag racing there is a term : There is no substitute for cubic inches and in most cases this is true. The same can be said for memory : There is no substitute for speed. In my opinion the two are similar. We are playing a game of who can get there the fastest. The ADATA XPG DDR 3 memory kit clearly leads the tests at DDR3 2133. Our tests how that ADATA lags behind the Kingston kit when it is timed the same as the Kingston Hyper X kit. Here’s the thing, this kit was not designed to run at those settings and is non standard settings for this kit. Which for the most part, I expected. Running at DDR3 2133 the ADATA kit has the advantage. Although some lower timings would be nice, in reality unless you are on the extreme end of the scale, you most likely will not notice the higher timings but will benefit from the higher speeds. Best of all it fits under most high performance tower coolers!.
