G.Skill Ripjaws X 4 GB (1x4GB DDR3-1333)

The G.Skill Ripjaws X 4 GB comes 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. 4GB gives you enough headroom for esports and everyday use; past 3600 MT/s, extra frequency brings diminishing returns.

DDR3 pricing in the high-end tier makes this a sensible pairing for older AM4 and LGA1700 boards that top out at DDR4. Its $169.99 price tag places it squarely in high-end territory.
