G.Skill Ripjaws V 64 GB (8x8GB DDR4-4000)

The G.Skill Ripjaws V 64 GB arrives as 8 modules of 8GB each with 64GB of DDR4 on board. It is specced for 4000 MT/s with a CAS latency of 15, working out to a true latency of about 7.5ns. Operating voltage sits at 1.35V.

As a high-end DDR4 kit, it slots naturally into older AM4 and LGA1700 boards that top out at DDR4. 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. At $176.90 it sits in the high-end memory kit bracket.
