Crucial CT2K2G3S1067M 4 GB (2x2GB DDR3-1066)

The Crucial CT2K2G3S1067M 4 GB ships as 2 modules of 2GB each with 4GB of DDR3 on board. It is specced for 1066 MT/s with a CAS latency of 7, working out to a true latency of about 13.1ns. Operating voltage sits at 1.35V.

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.
