Corsair Vengeance LPX 16 GB (2x8GB DDR4-4000)

The Corsair Vengeance LPX 16 GB ships as 2 modules of 8GB each with 16GB of DDR4 on board. It is rated at 4000 MT/s with a CAS latency of 19, working out to a true latency of about 9.5ns. Operating voltage sits at 1.35V.

Once memory clears 3600 MT/s, frequency gains taper off, so the 16GB on offer here is the spec that counts for modern AAA titles.
