SAMSUNG 16GB DDR4 2666 260 Pin SODIMM M471A2K43CB1-CTD

SKU CH-KCMZ-CPWRS

A 16 GB DDR4 SODIMM running at 2666 MHz with CL19 latency for notebook upgrades

  • Total capacity16 GB
  • 16 GB capacity upgrades notebook performance for demanding workloads
  • DDR4-2666 speed delivers 21300 MT/s bandwidth for responsive multitasking
  • CL19 latency and 1.20 V operation balance quick access with low power draw
  • 260-pin SoDIMM form factor fits standard laptop memory slots without adapters
  • Non-ECC unbuffered design keeps data flowing for everyday computing tasks

Capacity and form factor

This is a 16GB DDR4 SODIMM module built to the PC4-21300 standard with a 2666 MHz clock and CL19 latency. It uses a 260-pin edge connector and operates at 1.20 V, matching the electrical requirements for modern notebook memory slots. The stick measures 1.2 inches wide by 2.7 inches long.

Who this suits and who it does not

The module is intended for notebook owners or system integrators adding or replacing a single 16GB stick in a laptop that accepts unbuffered, non-ECC DDR4 SODIMMs. Buyers who need ECC error correction, registered signal processing, or a higher total capacity than one slot can provide should look at other configurations. Systems limited to lower DDR4 speeds will still run the module, but only at the platform's maximum supported rate.

Deciding specification

The critical figure is the 2666 MHz speed rating combined with the 260-pin SODIMM form factor; the laptop must support DDR4 at this frequency and accept the physical dimensions of 1.2 by 2.7 inches. If the machine requires a different pin count, a lower voltage, or a faster data rate, this module will not be compatible.

Questions about this item

Does the 1.2 V DDR4 module run cool and quiet inside a laptop chassis all day?

The SODIMM operates at 1.20 V with no moving parts, so it adds negligible heat and makes no audible noise during continuous use.

What must my notebook already provide for this 260-pin stick to be recognised?

A free DDR4 SODIMM slot that accepts 260-pin modules at 1.2 V and supports the PC4-21300 standard.

If I keep an existing DDR4 SODIMM, will this CL19 module run at the same speed?

The system will clock both modules to the lowest common speed and the loosest timing, so this stick will match the slower module automatically.
