DDR4 Single/Dual Channel 2400MHz RAM Memory Kits

DDR4 SDRAM is the fastest and most efficient consumer memory available. It's only compatible with Intel's Haswell E which run in quad-channel and Skylake CPUs which run in dual-channel. The latter is what these modules are designed for, so they're sold in matching kits of two modules for best performance or single modules for a cheap upgrade. These are the mid-range kits, with a speed of 2,400MHz.
