16GB DDR4 2933 Desktop Module

This 16GB DDR4 module runs at 2933 MT/s with CL21 latency and standard 1.20V operation. It uses a 288-pin unbuffered DIMM form factor built with major brand chips. The kit is aimed at desktop owners who need a straightforward capacity increase for everyday workloads.

Replaces Dell RMWRN SNPRMWRNC/16G AA101831 AA103689

The stick is a direct equivalent for the listed Dell part numbers, so it fits the same slots without changes. Swapping an older 8GB or slower DDR4 module for this 16GB unit is worthwhile when the system supports 2933 MT/s and the board has a free DIMM slot. No benefit appears if the platform caps memory speed below the rated frequency.

Handles mainstream multitasking

The single 16GB rank provides comfortable headroom for office suites, web browsing with many tabs, and 1080p video editing timelines. Capacity runs out with large virtual-machine clusters, heavy 3D rendering, or datasets that exceed 16GB of physical memory.
