Crucial CT51264BF186DJ 4 GB (1x4GB DDR3-1866)

The Crucial CT51264BF186DJ 4 GB arrives as a single module with 4GB of DDR3 on board. Operating voltage sits at 1.35V. It is rated at 1866 MT/s with a CAS latency of 13, working out to a true latency of about 13.9ns. Once memory clears 3600 MT/s, frequency gains taper off, so the 4GB on offer here is the spec that counts for esports and everyday use.

As a budget DDR3 kit, it slots naturally into older AM4 and LGA1700 boards that top out at DDR4. Expect to pay around $45.99, which lands it among budget options.
