SAMSUNG M471A2K43DB1-CWE_UB 16GB DDR4 3200MHz 2Rx8 SO-DIMM 260-Pin 1.2V accessory

SKU CH-P3A0-QM5SP MPN M471A2K43DB1-CWE_UB

16 GB DDR4 SO-DIMM laptop memory running at 3200 MHz with CL22 latency and dual-rank 2Rx8 configuration

  • 16 GB DDR4 capacity for multitasking headroom
  • 3200 MHz PC4-25600 speed for responsive performance
  • Dual-rank 2Rx8 organisation improves throughput
  • 2 V low voltage reduces power draw
  • 260-pin SO-DIMM fits standard laptop slots

16 GB DDR4 SO-DIMM for laptops

This Samsung module delivers 16 GB of DDR4 memory in a 260-pin SO-DIMM form factor. It operates at 3200 MHz with a CAS latency of CL22 and runs at the standard 1.2 V. The dual-rank 2Rx8 design suits notebooks that accept unbuffered non-ECC PC4-25600 memory.

Ideal for single-slot upgrades.

Builders adding capacity to a compatible laptop will find this module fits the standard SO-DIMM slot. Systems that require ECC error correction or registered DIMMs cannot use this stick. Buyers needing more than one module should verify their board supports multiple ranks.

Dual-rank 2Rx8 organisation at 3200 MHz

The memory is organised as 2Rx8, meaning two ranks of eight-bit wide chips. This rank structure affects compatibility with some laptop chipsets that limit the number of ranks per channel. Confirm the platform accepts dual-rank SO-DIMMs before purchase.

Questions about this item

Should I pick the 16GB 2Rx8 module or a single-rank alternative?

The 16GB 2Rx8 dual-rank module can improve throughput on memory controllers that benefit from rank interleaving, while single-rank sticks may allow higher frequencies on some platforms.

What does the 3200MHz rating deliver in a laptop?

The module runs at 3200MHz with CL22 latency, providing a peak transfer rate of PC4-25600 when the system memory controller supports that speed.

Does the 260-pin SO-DIMM DDR4 interface limit the usable speed?

The 260-pin SO-DIMM form factor carries DDR4 signals at 1.2V; actual operating speed is capped by the laptop's memory controller and BIOS, not by the socket itself.
