Mushkin 991556 2 GB (1x2GB DDR2-667)

The Mushkin 991556 2 GB ships as a single module with 2GB of DDR2 on board. Operating voltage sits at 1.35V. It is rated at 667 MT/s with a CAS latency of 5, working out to a true latency of about 15ns. As a budget DDR2 kit, it slots naturally into older AM4 and LGA1700 boards that top out at DDR4.

Once memory clears 3600 MT/s, frequency gains taper off, so the 2GB on offer here is the spec that counts for esports and everyday use. Its $32.32 price tag places it squarely in budget territory.
