Kingston KCP421SD8/16 16 GB (1x16GB DDR4-2133)

The Kingston KCP421SD8/16 16 GB comes as a single module with 16GB of DDR4 on board. Operating voltage sits at 1.35V. It is rated at 2133 MT/s with a CAS latency of 15, working out to a true latency of about 14.1ns. Once memory clears 3600 MT/s, frequency gains taper off, so the 16GB on offer here is the spec that counts for modern AAA titles.
