The G.Skill F4-4200C19Q2-64GTZKK 64 GB ships as 8 modules of 8GB each with 64GB of DDR4 on board. It is rated at 4200 MT/s with a CAS latency of 19, working out to a true latency of about 9ns. Operating voltage sits at 1.35V.

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.
