Crucial Ballistix 4 GB (1x4GB DDR3-1866)

The Crucial Ballistix 4 GB arrives as a single module with 4GB of DDR3 on board. Operating voltage sits at 1.35V. It is specced for 1866 MT/s with a CAS latency of 9, working out to a true latency of about 9.6ns. 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.
