4GB DDR4 3200MHz SODIMM for Laptops

This 4GB DDR4 module runs at 3200MHz with CL22 latency and 1.20V operation. It uses the 260-pin SO-DIMM form factor and is unbuffered non-ECC. The stick is built as a compatible replacement for the Samsung M471A5244CB0-CWE module.

Fits Standard Laptop Memory Slots

The module installs into any DDR4 SO-DIMM slot that accepts 260-pin memory at 1.20V. No extra power cables or cooling are required. Adding this stick frees up system resources by reducing swap-file activity when the original capacity was lower.

Upgrade from 2GB or Slower DDR4 Modules

Replacing a 2GB stick or a slower DDR4 module with this 4GB 3200MHz unit increases available memory and bandwidth. The jump is worth it when the laptop supports DDR4 3200 and the current configuration leaves headroom for a single-module upgrade.

이 상품에 대한 질문

Will the CL22 latency become the bottleneck during long rendering sessions?

CL22 is the rated CAS latency at 3200 MHz; the module runs at standard 1.20 V DDR4 voltage, so latency stays consistent under sustained load.

Does the stick run hot or draw extra power when the laptop is on all day?

It operates at the standard DDR4 1.20 V with no ECC or registered circuitry, so heat and power draw remain at baseline SO-DIMM levels.

My notebook only has 260-pin DDR4 slots — will this module fit without an adapter?

Yes, the 260-pin SO-DIMM form factor matches every standard DDR4 laptop slot; no adapter is required.
