Mushkin Proline 4 GB (1x4GB DDR3-1866)

The Mushkin Proline 4 GB arrives as a single module with 4GB of DDR3 on board. It is specced for 1866 MT/s with a CAS latency of 13, working out to a true latency of about 13.9ns. 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.
