G.Skill Ripjaws Z 16 GB (4x4GB DDR3-1866)

The G.Skill Ripjaws Z 16 GB ships as 4 modules of 4GB each with 16GB of DDR3 on board. It is specced for 1866 MT/s with a CAS latency of 9, working out to a true latency of about 9.6ns. Operating voltage sits at 1.35V. 16GB gives you enough headroom for modern AAA titles; past 3600 MT/s, extra frequency brings diminishing returns.

Builders shopping for older AM4 and LGA1700 boards that top out at DDR4 will find this high-end DDR3 option easy to justify. Its $128.02 price tag places it squarely in high-end territory.
