Kingston KHX1866C11D3P1K2/4G 4 GB (2x2GB DDR3-1866)

The Kingston KHX1866C11D3P1K2/4G 4 GB arrives as 2 modules of 2GB each with 4GB of DDR3 on board. Operating voltage sits at 1.35V. It is specced for 1866 MT/s with a CAS latency of 11, working out to a true latency of about 11.8ns. 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.
