With the introduction of Intel's X79 Express chipset, enthusiasts must now consider quad-channel memory kits, and vendors like Kingston are rushing to assert themselves in this new market. Pushing 4GB DDR3 modules to a very high 2133MHz frequency, Kingston's new KHX2133C11D3K4 kit offers 16GB of high-performance memory for your new LGA 2011 rig. Benchmark Reviews runs it through our test suite to see how it performs.

High performance memory is one facet of a high performance system; a balanced approach to system performance considers processor speed, the amount of memory (as well as the speed), the GPU (for gamers), and the storage device (hard disk or SSD). Enthusiasts commonly concentrate on one or two of these items to the exclusion of others, which leads to systems that produce great benchmarks scores in some instances but drag in others.

Increasing CPU speed and on-chip cache memory has reduced the performance impact of high-speed system memory relative to older systems. Kingston's DDR3-2133 quad channel 16GB kit is much more expensive than the more common DDR3-1600 kits. Does this extra money buy a commensurate amount of extra performance? Let's run the tests.
