SAMSUNG M471A2K43DB1-CWE_UA 16GB DDR4 SO-DIMM 3200MHz 2Rx8 1.2V accessory

SKU CH-A4Z1-04WS3 MPN M471A2K43DB1-CWE_UA

16 GB DDR4 SO-DIMM laptop memory running at 3200 MHz with 2Rx8 rank and 1.2 V operation

  • 16GB DDR4 capacity boosts multitasking headroom
  • 3200MHz speed delivers responsive data throughput
  • 2V operation reduces laptop power draw
  • 2Rx8 dual-rank layout optimises bandwidth efficiency
  • 260-pin SO-DIMM fits standard notebook slots

Capacity & fit

This is a 16GB DDR4 SO-DIMM built for laptop memory upgrades. It suits owners of compatible notebooks who need a single module to add or replace system RAM. Buyers whose devices require ECC, registered DIMMs, or a different pin count cannot use this part.

Deciding spec

The module runs at 3200MHz on a PC4-25600 bus with a 2Rx8 rank layout and 1.2V operation. Matching these exact figures to your laptop's memory specification is the only way to confirm compatibility. Systems that demand a different speed, voltage, or rank organisation will not accept this module.

Sustained behaviour

Samsung DRAM rated for continuous 3200MHz throughput maintains stable data rates during extended workloads. The 2Rx8 organisation and unbuffered design keep latency predictable when the memory controller is saturated for long periods. No thermal throttling or voltage drift occurs within the specified 1.2V envelope.

Questions about this item

How does the 3200MHz rating affect real laptop performance?

The module runs at 3200MHz, so the memory controller can transfer data at that clock rate when the platform supports it.

What does the PC4-25600 designation mean for compatibility?

PC4-25600 identifies the DDR4-3200 data rate; the laptop must accept DDR4 SO-DIMMs at that speed.

Will the 260-pin SO-DIMM fit my notebook slot?

It uses the standard 260-pin SO-DIMM form factor used by most DDR4 laptops.
