Mushkin Essentials 4 GB (1x4GB DDR2-667)

The Mushkin Essentials 4 GB ships as a single module 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. Expect to pay around $16.99, which lands it among budget options.
