SAMSUNG M471A5244CB0-CTD_UA 4GB DDR4 2666MHz SO-DIMM accessory

SKU CH-X86H-5SWP6 MPN M471A5244CB0-CTD_UA

A 4GB DDR4 SO-DIMM laptop memory module running at 2666MHz with CL19 latency and 1.2V operation

  • Adds 4 GB of DDR4 memory for smoother multitasking
  • Runs at 2666 MHz for responsive system performance
  • Low 1.2 V operation reduces laptop power draw
  • CL19 latency keeps data access quick
  • 260-pin SO-DIMM fits standard laptop slots

Capacity and fit

This is a 4GB DDR4 SO-DIMM module built for laptops that accept 260-pin memory. It suits owners who need a single stick to fill one slot or to add capacity to an empty bay.

Sustained behaviour

The module runs at 2666MHz with CL19 latency and 1.2V voltage, delivering steady throughput for everyday multitasking. Non-ECC operation means data integrity relies on the system controller rather than on-module correction.

Thermals and power

Low-voltage DDR4 architecture keeps heat output modest during normal workloads. The slim SO-DIMM profile fits tight chassis spaces without obstructing airflow or adding audible noise.

Questions about this item

How much heat and power does this 1.2 V DDR4 SO-DIMM add when the laptop runs all day?

At 1.2 V the module draws minimal power and produces little extra heat during continuous use.

What must the laptop already provide for this 260-pin DDR4 module to work?

The system needs a free DDR4 SO-DIMM slot that accepts 260-pin PC4-21300 memory at 2666 MHz.

Will this CL19 2666 MHz stick run correctly alongside the original module I keep installed?

The memory controller will set both sticks to the lowest common speed and latency, so the original module remains usable.
