G.Skill Ripjaws V 64 GB (2x32GB DDR4-4000)

The G.Skill Ripjaws V 64 GB comes as 2 modules of 32GB each with 64GB of DDR4 on board. It is specced for 4000 MT/s with a CAS latency of 18, 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. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current memory kit prices across retailers. Support and warranty service run through G.Skill, with terms that vary by region.
