SAMSUNG M471A1K43EB1-CWE_UA 8GB DDR4 3200MHz SO-DIMM accessory

SKU CH-GRE5-Q4BA4 MPN M471A1K43EB1-CWE_UA

An 8 GB DDR4 laptop module running at 3200 MHz with CL22 latency and 1.2 V operation

  • Adds 8 GB DDR4 capacity for smoother multitasking
  • Runs at 3200 MHz PC4-25600 for faster data throughput
  • Low 1.2 V operation reduces power draw and heat
  • CL22 latency and 1Rx8 rank deliver responsive performance
  • 260-pin SO-DIMM fits standard laptop memory slots

Laptop Memory Upgrade

This Samsung SO-DIMM module adds 8GB of DDR4 memory to compatible laptops. It runs at 3200MHz with CL22 latency and operates at the standard 1.2V voltage. The non-ECC, unbuffered design suits mainstream consumer notebooks. Buyers who need error-correcting code memory for workstation tasks cannot use this module.

Build Integration

The 260-pin form factor fits standard DDR4 SO-DIMM slots in laptops. Installation requires no extra cables, adapters or drivers beyond the system BIOS recognising the PC4-25600 speed. The single-rank 1Rx8 organisation leaves a second slot free for a future capacity increase. Systems limited to lower DDR4 speeds will downclock the module automatically.

Upgrade Context

This part replaces an existing 4GB or 8GB DDR4 stick to raise total system memory. The jump is worthwhile when current usage regularly exhausts available RAM and causes paging. It does not add a second channel if the laptop has only one soldered module and no empty slot. Matching the original part number ensures compatibility.

  • Low 1.2 V operation reduces power draw and heat
  • CL22 latency and 1Rx8 rank deliver responsive performance

Questions about this item

Will the CL22 latency bottleneck performance during long rendering sessions?

CL22 is the rated CAS latency at 3200 MHz; sustained workloads run at this timing without further degradation.

Does the 1.2 V module run hot or loud inside a thin ultrabook chassis?

The SO-DIMM operates at 1.2 V with no moving parts, so it adds negligible heat and zero noise during all-day use.

My laptop only has one free SO-DIMM slot — will this single 8 GB stick work alone?

Yes, the 1Rx8 unbuffered module is designed to run as a single stick in any compatible 260-pin DDR4 slot.
