Corsair ValueSelect 4 GB (1x4GB DDR4-2133)

The Corsair ValueSelect 4 GB arrives as a single module with 4GB of DDR4 on board. It is rated at 2133 MT/s with a CAS latency of 15, working out to a true latency of about 14.1ns. Operating voltage sits at 1.35V. 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.
