This is a single 16GB DDR4 laptop memory module from Samsung, part M471A2K43DB1-CTD. It runs at 2666MHz (PC4-21300) at 1.2V, is dual rank (2Rx8), non-ECC and unbuffered, and fits 260-pin SODIMM slots. It suits laptop owners adding or replacing memory to speed up multitasking, and Samsung's own-module build is generally trusted for stability where cheaper no-name sticks are a gamble. Dual rank gives slightly better bandwidth than single-rank sticks of the same speed, though some laptops prefer single-rank modules.
