Continual improvements in CPU technology have limited the potential of high-speed system memory as a means of increasing performance for everyday tasks. Better-specified RAM does make sense if you're intent on running integrated graphics, however, as they pull their framebuffer from the main pool of system memory.

Appreciating that there aren't quantum leaps in performance for systems housing discrete graphics cards, faster memory therefore makes sense if it can be purchased as a relatively cheap upgrade over generic RAM. Taiwanese manufacturer G.Skill splits its desktop range into no fewer than 12 brands, which are further differentiated into various speeds, latencies and modules. The RipjawsX line is home to a veritable cornucopia of modules ranging from DDR3-1,333MHz to DDR3-2,400MHz speeds. Today, we're taking a look at a quad-module pack rated at DDR3-2,133MHz.
