Overview

Samsung Electronics' 16GB DDR5-5600MHz SODIMM module, model M425R2GA3BB0-CWM, is an excellent choice for laptop users seeking a fast and reliable memory upgrade. This module supports the latest DDR5 standard, offering data transfer speeds of 5600MHz with a PC5-44800 bandwidth rating. It features a single-rank (1Rx8) configuration and operates at a low voltage of 1.1V, minimizing impact on battery life. As a JEDEC-standard Non-ECC unbuffered module, it is compatible with a wide range of mainstream laptops and all-in-one PCs. Upgrading to 16GB significantly improves system responsiveness for everyday multitasking, office work, and even light creative tasks.

Compatibility Guide

Form Factor: 262-pin SO-DIMM (Small Outline Dual Inline Memory Module). Memory Standard: DDR5-5600 (PC5-44800). However, not all systems support 5600MHz; the module will run at the highest speed supported by the CPU and motherboard according to JEDEC SPD. Compatible Devices: Laptops, mini PCs, and all-in-one PCs with DDR5 support, typically based on Intel 12th Gen (Alder Lake) or later, and AMD Ryzen 6000 series (Rembrandt) or later. Note: This SODIMM is not compatible with DDR4 slots. Ensure your system has DDR5 SO-DIMM slots. Also, some ultra-thin laptops require single-rank modules; this module is single-rank (1Rx8), which helps with compatibility.

Product Info

This Samsung OEM module carries the model number M425R2GA3BB0-CWM. It is a 16GB single stick, running at 5600MHz with CAS latency CL46, voltage 1.1V, and a single-rank x8 configuration (Non-ECC unbuffered). In the market, it sits in the entry to mid-range segment for DDR5 SODIMMs, offering a solid balance of price and performance. The product has been available since 2023 through major retailers like and electronics stores. Warranty typically covers one year from Samsung or the reseller, depending on the purchase channel.

Best Use Cases

Upgrading from 8GB to 16GB in a laptop used for daily multitasking—running many browser tabs, office applications, and light productivity software. The extra memory and speed noticeably reduce lag and improve responsiveness. Creative professionals using laptops for photo editing or basic video editing. The 5600MHz bandwidth helps with faster data transfers, making previews and export times shorter. Users building or upgrading a compact or portable PC who value low power consumption and heat generation. Single-rank modules like this one are ideal for power-efficient builds.

Things to Consider

This is a single 16GB module. For dual-channel operation, you must install two identical modules in the correct slots. Running only one stick halves memory bandwidth, which can impact performance in memory-intensive tasks. The 5600MHz speed is only guaranteed if the CPU and motherboard support it natively. Older DDR5 platforms may downclock to 4800MHz. Check your system’s maximum supported memory speed before purchase. CL46 is standard for DDR5-5600, but faster kits with CL40 or CL34 exist. The real-world performance difference is small for most applications, but latency-sensitive workloads may see a minor benefit from tighter timings. Some laptops have physical constraints (height, PCB thickness) that may prevent installation of certain SODIMMs. Always consult your laptop’s service manual for approved memory part numbers. Pricing is around ¥45,675 (approx. $320 USD at time of writing, reference). This is slightly higher than competing brands but reflects Samsung’s reputation for reliability and consistent quality.
