SAMSUNG M471A1K43DB1 16GB 2x8GB DDR4 2666MHz CL19 laptop RAM

SKU CH-VB6A-AP472 MPN M471A1K43DB1

A 16 GB dual-channel DDR4 laptop memory kit running at 2666 MHz with CL19 latency and 1.2 V operation

  • 16 GB total capacity from two 8 GB modules
  • DDR4 SO-DIMM runs at 2666 MHz PC4-21300 speed
  • Low 1.2 V voltage reduces power draw
  • CL19 CAS latency for responsive timing
  • 260-pin non-ECC laptop form factor

Kit Composition

This kit supplies 16 GB of DDR4 laptop memory in a matched pair of 8 GB SO-DIMM modules. Each stick uses a 1Rx8 organisation and runs at 2666 MHz with CL19 latency at 1.2 V. The 260-pin form factor fits standard DDR4 SO-DIMM slots found in many notebooks and compact workstations.

Ideal Users and Limits

The kit suits owners who need to reach 16 GB total capacity in a system that accepts DDR4 SO-DIMMs and can operate at the rated speed and voltage. It is not for machines that require ECC error correction, modules with a different pin count, or a higher-density single-stick upgrade beyond 8 GB per slot.

Capacity and Headroom

The 16 GB total provides comfortable headroom for everyday multitasking, office suites, web browsing with many tabs and light creative workloads. Demanding tasks such as large video timelines, heavy virtualisation or extensive data-set processing will exhaust the available memory and require a platform that supports a larger total capacity.

Questions about this item

Does this 260-pin SO-DIMM kit need anything beyond a free DDR4 laptop slot to work?

It fits a standard 260-pin DDR4 SO-DIMM slot and runs at 1.2 V, so a compatible laptop with an empty slot is all that is required.

Will the CL19 timing on this 2666MHz kit slow down my existing DDR4 memory?

The system will run all installed DDR4 modules at the lowest common speed and latency, so existing memory will match this kit's 2666MHz CL19 settings.

How can I confirm both 8GB modules are detected at 2666MHz after installation?

Check the memory section in your BIOS or a system-information tool; it should show 16GB total, 2666MHz, and CL19 timings.
