DDR4 Quad Channel 2666MHz RAM Memory Kits

DDR4 SDRAM is the fastest and most efficient consumer memory available. At present, it's only compatible with Intel's X99 motherboards, which run in quad-channel. That's what these modules are designed for, so they're sold in matching kits of four or eight. These are the most premium, fastest kits around, with speeds starting at 2,666MHz and reaching 3,333MHz.
