Samsung M426R4GA3BB0-CQK 32GB Overview

The Samsung M426R4GA3BB0-CQK 32GB 4800MHz PC5-38400 1.1V DDR5 SDRAM 262-Pin SODIMM CL46 ECC 2Rx8 Memory Module sits at the intersection of modern DDR5 performance and enterprise-class reliability. This detailed category description explores the technical features, compatibility considerations, installation best practices, and real-world use cases for retailers, system integrators, and technical buyers comparing memory modules for compact high-performance systems. The content below emphasizes keyword-rich phrases and long-tail search terms such as DDR5 SODIMM ECC 32GB 4800MHz, PC5-38400 ECC memory for compact workstations, and Samsung server-grade SODIMM modules, designed to improve discoverability on search engines for category pages and product listings.

Core Specifications

Capacity and Density: 32GB Single Module

A single 32GB module provides a substantial memory footprint for multi-tasking, virtualization, and memory-critical applications. For category shoppers, highlight how 32GB DDR5 SODIMM modules are increasingly the baseline for advanced mobile workstations and compact servers that must run modern operating systems and memory-hungry workloads without relying on swap.

Speed and Bandwidth: 4800MHz (PC5-38400)

The 4800MHz data rate — marketed as PC5-38400 — defines raw memory bandwidth and is a key differentiator between legacy DDR4 solutions and current DDR5 SODIMM offerings. Explain that 4800MT/s improves throughput and lowers latency for bursty memory access patterns in database caching, scientific computation, and content creation workflows.

Latency: CL46

The CAS Latency of CL46 is characteristic of DDR5 at this clock speed. While absolute latency numbers may be higher than lower-frequency DDR4 timings, the effective performance is elevated by wider internal banks, burst lengths, and DDR5 architectural improvements. For shoppers focused on latency-sensitive tasks, explain latency in plain language: CL46 indicates the number of clock cycles to access requested data; combined with higher frequency, effective read/write times remain competitive for real-world applications.

Voltage and Power Efficiency: 1.1V

Operating at 1.1V, DDR5 SODIMM modules improve power efficiency compared to some DDR4 variants. Lower voltage reduces thermal output and is beneficial in thermally constrained compact systems. This feature supports long battery life in mobile workstations and reduces cooling requirements for small chassis servers.

Form Factor and Pin Count: 262-Pin SODIMM

The 262-pin SODIMM form factor is the standard physical configuration for modern DDR5 compact system memory. Clarify compatibility considerations: motherboards explicitly designed for DDR5 SODIMM are required; this module will not physically fit or operate in DDR4 slots. Using phrases like 262-pin DDR5 SODIMM compatibility helps connect search intent for buyers seeking form-factor guidance.

Error Correction: ECC and 2Rx8 Organization

ECC (Error-Correcting Code) support elevates this module to enterprise-class reliability by detecting and correcting single-bit memory errors. The 2Rx8 ranking indicates a dual-rank organization with 8-bit wide DRAM chips, relevant in server and workstation BIOS/UEFI settings. For category copy, emphasize how ECC SODIMM modules are increasingly supported by mobile server platforms and workstation motherboards that prioritize data integrity, making the module suitable for professional environments where reliability is non-negotiable.

Compatibility and Use Cases

Compatible Systems and Platforms

The Samsung M426R4GA3BB0-CQK targets DDR5-capable compact workstations, embedded systems, and certain small-form-factor servers that accept 262-pin DDR5 SODIMM modules with ECC support. Use this module in any platform that explicitly lists support for DDR5 ECC SODIMM memory — common in enterprise R&D workstations, and edge servers. Note that many consumer may accept non-ECC SODIMMs only; always cross-reference motherboard specifications and BIOS release notes.

Use Cases

• Virtualization & Container Hosts: 32GB modules enable greater virtual machine density on compact systems that otherwise would be memory-limited.
• Edge and Embedded Servers: Compact servers in edge deployments benefit from ECC at SODIMM form factor for increased uptime and data integrity.
• Professional Content Creation: Video editing, 3D rendering, and multitasking benefit from high frequency and large capacity.
• Scientific and Financial Applications: Memory bandwidth and ECC improve determinism and data correctness in simulations and analytics.

Performance

Real-World Throughput vs. Theoretical Numbers

Marketing figures such as 4800MHz and PC5-38400 represent theoretical throughput; real-world performance depends on CPU memory controller, dual-channel configurations, and software behavior. Offer practical guidance for technical buyers: pairing two identical modules in matched channels (e.g., two 32GB DIMMs) maximizes throughput and enables full-channel interleaving, which is critical for bandwidth-limited tasks.

Thermal and Power Profiles

The 1.1V power envelope reduces thermal stress on modules and host systems. Emphasize the importance of thermal headroom in thin-and-light mobile workstations, where passive cooling is common. For dense deployments, advise administrators to monitor operating temperature under sustained load and consult server vendor thermal profiles to ensure long-term reliability.

Comparison

DDR5 SODIMM vs DDR4 SODIMM

Articulate the clear generational improvements: higher frequency potential, improved channel architecture, on-die ECC capabilities in some designs, and power efficiency. For buyers considering upgrades, explain that DDR5 modules cannot work in DDR4 slots and vice versa — compatibility is strictly determined by the host memory controller and physical slot.

ECC SODIMM vs Non-ECC SODIMM

Distinguish the use-cases for ECC: mission-critical systems, servers, and professional workstations that require error correction. Non-ECC SODIMMs may suffice for consumer gaming machines where cost and raw peak performance often take precedence over data integrity.

Buffered vs Unbuffered Modules

Clarify that SODIMM modules, including the Samsung M426R4GA3BB0-CQK, are typically unbuffered or registerless for SODIMM form factors. Buffered (registered) memory is more common in large-scale server DIMMs. Describe how registered memory differs and why SODIMMs target mobile and compact server platforms.
