Samsung M393A4K40CB2-CTD 32 GB (1x32GB DDR4-2666)

The Samsung M393A4K40CB2-CTD 32 GB arrives as a single module with 32GB of DDR4 on board. Operating voltage sits at 1.35V. It is specced for 2666 MT/s with a CAS latency of 19, working out to a true latency of about 14.3ns. As a high-end DDR4 kit, it slots naturally into older AM4 and LGA1700 boards that top out at DDR4.

32GB gives you enough headroom for gaming plus heavy multitasking and content work; past 3600 MT/s, extra frequency brings diminishing returns. At $199.00 it sits in the high-end memory kit bracket.
