Kingston Blu 4 GB (1x4GB DDR3-1333)

The Kingston Blu 4 GB ships as a single module with 4GB of DDR3 on board. It is rated at 1333 MT/s with a CAS latency of 9, working out to a true latency of about 13.5ns. Operating voltage sits at 1.35V. As a budget 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. Its $23.81 price tag places it squarely in budget territory.
