Mushkin Essentials 4 GB (2x2GB DDR2-667)

The Mushkin Essentials 4 GB ships as 2 modules of 2GB each with 4GB of DDR2 on board. It is specced for 667 MT/s with a CAS latency of 5, working out to a true latency of about 15ns. 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.

Builders shopping for older AM4 and LGA1700 boards that top out at DDR4 will find this budget DDR2 option easy to justify. At $16.99 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.
