Overview
The Crucial CT4K16G4DFD8266 64 GB ships as 4 modules of 16GB each with 64GB of DDR4 on board. It is specced for 2666 MT/s with a CAS latency of 19, working out to a true latency of about 14.3ns. Operating voltage sits at 1.35V.
As a premium 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 $497.99 it sits in the premium memory kit bracket.
