Corsair CMV4GX4M1A2133C15 4 GB (1x4GB DDR4-2133)

The Corsair CMV4GX4M1A2133C15 4 GB comes as a single module with 4GB 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. Once memory clears 3600 MT/s, frequency gains taper off, so the 4GB on offer here is the spec that counts for esports and everyday use.
