Corsair XMS3 12 GB (6x2GB DDR3-1333)

The Corsair XMS3 12 GB comes as 6 modules of 2GB each with 12GB of DDR3 on board. It is specced for 1333 MT/s with a CAS latency of 9, working out to a true latency of about 13.5ns. Operating voltage sits at 1.35V. Once memory clears 3600 MT/s, frequency gains taper off, so the 12GB on offer here is the spec that counts for esports and everyday use.
