Samsung 16GB DDR4 PC4-21300 2666MHz 288 Pin DIM Desktop Memory Module

The Samsung M378A2K43CB1-CTD is a 16 GB DDR4 memory module for desktop computers that use 288-pin DDR4 DIMM slots. It delivers PC4-21300 bandwidth and moves data at 2666 megatransfers per second while drawing only 1.2 volts. The module follows a dual-rank x8 organization built from sixteen 1 G x 8 components, and it reaches CAS latency 19 to keep everyday tasks running smoothly without the overhead of error correction.

This module is an easy drop-in upgrade for users who need more headroom in office desktops, home workstations, or entry-level gaming rigs. A single 16 GB stick preserves additional slots for future expansion, and the design is non-ECC and unbuffered, so it works with the vast majority of consumer Intel and AMD motherboards without special BIOS adjustments. If your current system slows down when multiple browser tabs, productivity apps, or light creative tools are open, replacing lower-capacity RAM with this Samsung module can restore the responsiveness you expect.
