Kingston KCP421ND8/16 16 GB (1x16GB DDR4-2133)

The Kingston KCP421ND8/16 16 GB ships as a single module with 16GB of DDR4 on board. Operating voltage sits at 1.35V. It is specced for 2133 MT/s with a CAS latency of 15, working out to a true latency of about 14.1ns. Builders shopping for older AM4 and LGA1700 boards that top out at DDR4 will find this high-end DDR4 option easy to justify.

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. Expect to pay around $129.98, which lands it among high-end options.
