Crucial CT4G3S1339M 4 GB (1x4GB DDR3-1333)

The Crucial CT4G3S1339M 4 GB arrives as a single module with 4GB of DDR3 on board. Operating voltage sits at 1.35V. It is rated at 1333 MT/s with a CAS latency of 9, working out to a true latency of about 13.5ns. As a budget DDR3 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 4GB on offer here is the spec that counts for esports and everyday use. At $19.99 it sits in the budget memory kit bracket.
