Kingston HyperX Blu 4 GB (2x2GB DDR3-1600)

The Kingston HyperX Blu 4 GB arrives as 2 modules of 2GB each with 4GB of DDR3 on board. It is specced for 1600 MT/s with a CAS latency of 9, working out to a true latency of about 11.3ns. Operating voltage sits at 1.35V. Builders shopping for older AM4 and LGA1700 boards that top out at DDR4 will find this budget DDR3 option easy to justify.

4GB gives you enough headroom for esports and everyday use; past 3600 MT/s, extra frequency brings diminishing returns. Its $49.99 price tag places it squarely in budget territory.
