Samsung 8GB DDR4 PC4-21300 2666MHZ Memory Module

The Samsung M471A1K43DB1-CTD is an 8 GB DDR4 memory module built in a 260-pin SODIMM format for laptops and compact desktops that rely on notebook memory. With a clock speed of 2666 MHz and a PC4-21300 rating, it delivers the bandwidth required for smoother multitasking, faster application loading, and snappier overall system response.

This module draws just 1.2 V, so it helps keep power consumption and heat generation low, a detail that benefits battery-powered notebooks and small form factor systems with limited cooling. The single-rank 1R x 8 layout is widely supported, making it an easy drop-in replacement or addition to most systems that already use DDR4 2666 memory.

Whether you are a student juggling dozens of browser tabs, a professional working in office suites and virtual meetings, or a casual gamer looking to reduce in-game stutter, upgrading to this Samsung module can give an aging laptop a noticeable performance lift without replacing the entire machine.
