M425R2GA3BB0-CQK Samsung 1x16GB DDR5 Unbuffered SO-DIMM RAM

High-Density DDR5 SO-DIMM Memory Expansion with the M425R2GA3BB0-CQK for Space-Constrained Platforms

The M425R2GA3BB0-CQK is a Samsung DDR5 SO-DIMM designed for enterprise notebook-class and small form factor systems that require predictable JEDEC behavior and efficient power delivery. As a 16GB, 262-pin low-profile module, it targets DDR5-capable CPU platforms where memory bandwidth and latency consistency directly impact virtualization density, container scheduling, and edge analytics responsiveness.

Built as an unbuffered, single-rank x8 DDR5 SO-DIMM, the M425R2GA3BB0-CQK operates at 4800MT/s (PC5-38400S) with CL40-39-39 timings at 1.1V to support modern DDR5 memory controllers without proprietary tuning. DDR5’s native on-die ECC enhances signal integrity within the DRAM array, helping maintain stable operation in compact chassis with constrained airflow. The 30mm low-profile height supports dense SFF deployments, while the SO-DIMM form factor preserves PCIe expansion and storage bay layouts by avoiding larger DIMM real estate.

Why Choose the M425R2GA3BB0-CQK?

The M425R2GA3BB0-CQK delivers a balanced density-to-power profile for DDR5 SO-DIMM platforms that must scale memory capacity without increasing thermal load or redesigning the enclosure. It enables straightforward capacity uplift in fleet-managed systems, supports repeatable configuration baselines, and reduces qualification complexity for standardized DDR5 4800MT/s deployments across edge nodes and mobile workstations.

Samsung memory engineering emphasizes controller compatibility, consistent SPD programming, and manufacturing discipline aligned with enterprise lifecycle planning. The module design supports modern data center and edge standards where validated component sourcing, long-term availability, and stable electrical characteristics are essential for operational continuity.

Key Applications:

• DDR5 SO-DIMM notebook and mobile workstation upgrades
• Edge appliances and embedded compute nodes
• Small form factor virtualization hosts
• General-purpose DDR5 SO-DIMM capacity expansion
