Crucial Ballistix Sport 4 GB (2x2GB DDR2-800)

The Crucial Ballistix Sport 4 GB ships as 2 modules of 2GB each with 4GB of DDR2 on board. It is rated at 800 MT/s with a CAS latency of 5, working out to a true latency of about 12.5ns. Operating voltage sits at 1.35V. As a budget DDR2 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 $37.99 it sits in the budget memory kit bracket. PlanMyPC's builder flags compatibility problems automatically and tracks the latest memory kit deals from multiple stores.
