Although the memory controller built into Intel's Socket 1156 processors only supports DDR3-1333 speeds officially, any enthusiast knows that there's more than a bit of overclocking headroom there. DDR3-1600 memory is increasingly common, and recently a number of memory vendors have upped the ante even more, with DDR3-2000 and higher speeds becoming available. G.SKILL has entered the enthusiast memory market with a broad selection of high-speed and low-latency memory kits, and Benchmark Reviews tests their new DDR3-2133 memory kit (F3-17066CL7D-4GBPIS) to see what kind of performance benefits it will yield when overclocked.
