Crucial CT12864AA667 1 GB (1x1GB DDR2-667)

The Crucial CT12864AA667 1 GB ships as a single module with 1GB 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. Builders shopping for older AM4 and LGA1700 boards that top out at DDR4 will find this budget DDR2 option easy to justify.

Once memory clears 3600 MT/s, frequency gains taper off, so the 1GB on offer here is the spec that counts for esports and everyday use. Its $18.59 price tag places it squarely in budget territory.
