Corsair CMSX4GX4M1A2400C16 4 GB (1x4GB DDR4-2400)

The Corsair CMSX4GX4M1A2400C16 4 GB ships as a single module with 4GB of DDR4 on board. It is rated at 2400 MT/s with a CAS latency of 16, working out to a true latency of about 13.3ns. 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.
