Corsair Vengeance LPX 64 GB (4x16GB DDR4-4000)

The Corsair Vengeance LPX 64 GB comes as 4 modules of 16GB each with 64GB of DDR4 on board. Operating voltage sits at 1.35V. It is rated at 4000 MT/s with a CAS latency of 18, working out to a true latency of about 9ns.

Once memory clears 3600 MT/s, frequency gains taper off, so the 64GB on offer here is the spec that counts for gaming plus heavy multitasking and content work.
