Genuine Samsung DDR4 SO-DIMM module

This Samsung M471A1K43BB1-CTD is an 8GB DDR4 laptop memory module rated at 2666MHz with a CAS latency of CL11. It operates at the standard 1.2V voltage and uses a 1Rx8 single-rank configuration across 288 pins. The module is new and intended as a direct replacement or upgrade for compatible notebook systems requiring DDR4 SO-DIMM memory.

Suitable for standard DDR4 laptop upgrades

This module suits users upgrading a laptop that accepts DDR4 SO-DIMM memory at 2666MHz with CL11 timing and 1.2V operation. It is not for systems requiring ECC registered memory, modules with different pin counts, or voltages other than 1.2V. Buyers needing higher capacities per slot or different form factors such as DIMM should look elsewhere.

2666MHz DDR4 speed rating confirms compatibility

The decisive specification is the 2666MHz (PC4-21300) speed rating combined with CL11 latency and 1.2V voltage. Verify that your laptop's memory controller supports this exact speed and timing before purchase. The 1Rx8 organization and 288-pin SO-DIMM interface are fixed characteristics of this specific module.

Questions about this item

How can I confirm the module runs at 2666 MHz CL11 after installation?

Open Task Manager or BIOS and verify the speed shows 2666 MHz with timings at CL11; the module operates at 1.2 V so no extra voltage setting is needed.

What is included and what must be sourced separately?

The box contains one 8 GB DDR4 SO-DIMM (model M471A1K43BB1-CTD, 1Rx8); a compatible laptop slot and any tools for opening the chassis are not supplied.

Which version should I pick if my laptop only accepts 1.2 V DDR4 SO-DIMMs?

This single 8 GB stick is 1.2 V DDR4 with 288 pins and CL11, matching that requirement exactly.
