Corsair Vengeance LP 8 GB (2x4GB DDR3-2133)

The Corsair Vengeance LP 8 GB ships as 2 modules of 4GB each with 8GB of DDR3 on board. It is specced for 2133 MT/s with a CAS latency of 9, working out to a true latency of about 8.4ns. Operating voltage sits at 1.35V. Once memory clears 3600 MT/s, frequency gains taper off, so the 8GB on offer here is the spec that counts for esports and everyday use.
