Patriot Viper 4 GB (1x4GB DDR3-1866)

The Patriot Viper 4 GB arrives as a single module with 4GB of DDR3 on board. It is rated at 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. As a mid-range DDR3 kit, it slots naturally into older AM4 and LGA1700 boards that top out at DDR4.

4GB gives you enough headroom for esports and everyday use; past 3600 MT/s, extra frequency brings diminishing returns. At $95.44 it sits in the mid-range memory kit bracket.
