SKU CH-H9VJ-QRE0A MPN M471A2K43CB1-CTD_UA

A 16GB DDR4 SO-DIMM laptop memory module running at 2666MHz with CL19 latency and 1.2V operation

  • 16 GB DDR4 SO-DIMM expands laptop memory capacity
  • 2666 MHz PC4-21300 speed supports responsive multitasking
  • Dual-rank 2Rx8 organisation improves data throughput
  • CL19 latency at 1.2 V balances performance and efficiency
  • 260-pin non-ECC module fits standard laptop slots

Samsung 16 GB DDR4 SO-DIMM 2666 MHz

This Samsung memory module delivers 16 GB of DDR4 capacity in a 260-pin SO-DIMM form factor. It is built for laptops that require PC4-21300 speed at 2666 MHz. The dual-rank 2Rx8 organisation and CL19 latency suit everyday multitasking and office workloads.

Non-ECC 1.2 V operation

The module runs at 1.2 V without error-correction circuitry. This makes it compatible with standard consumer laptop memory controllers that expect non-ECC DDR4 SO-DIMMs. Systems requiring registered or ECC memory will not accept this part.

Suits mainstream laptop upgrades

Ideal for users adding a single 16 GB stick to a free slot or replacing an existing module in a compatible notebook. Not for desktops needing full-size DIMMs, for servers requiring ECC, or for platforms limited to lower DDR4 speeds.

Questions about this item

What does the 2666MHz rating mean once the module is installed in a laptop?

The 2666MHz speed sets the maximum data rate the memory can sustain when the system runs at its rated PC4-21300 bandwidth.

Which interface standard does this SO-DIMM use and what practical limit does it impose?

It uses the DDR4 SO-DIMM 260-pin interface, which caps the module at the PC4-21300 transfer rate and CL19 latency.

What physical slot and clearance does this module need to fit?

It requires a standard 260-pin DDR4 SO-DIMM slot and fits the low-profile height used in most laptops.
