Corsair XMS3 4 GB (1x4GB DDR3-1600)

The Corsair XMS3 4 GB arrives as a single module with 4GB of DDR3 on board. It is rated at 1600 MT/s with a CAS latency of 7, working out to a true latency of about 8.8ns. 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.
