Key Features & Benefits

• Massive 128GB Capacity per DIMM: Enables extreme memory density configurations, allowing servers to reach multi-terabyte total RAM with fewer physical slots — critical for large VM consolidation ratios and in-memory analytics.
• DDR4-3200 Speed (PC4-25600): Delivers a theoretical peak bandwidth of approximately 25,600 MB/s per module, significantly accelerating data throughput for latency-sensitive enterprise applications and high-performance computing tasks.
• ECC (Error-Correcting Code) Support: Automatically detects and corrects single-bit memory errors in real time, preventing data corruption and system crashes — a non-negotiable requirement for financial systems, healthcare records, and enterprise databases.
• Registered (Buffered) RDIMM Architecture: The register chip on the DIMM acts as an electrical buffer between the memory controller and DRAM chips, enabling support for high-capacity DIMMs in multi-module configurations without compromising signal integrity or stability.
• Samsung Original DRAM: Fabricated using Samsung's own advanced DRAM process nodes, delivering industry-leading reliability metrics, tighter tolerances, and superior long-term operational consistency compared to modules using third-party DRAM.
• New Pulled Condition — Cost-Optimised: Sourced from professionally decommissioned OEM systems, fully tested and verified to meet original factory specifications, offering substantial cost savings without sacrificing enterprise-grade performance or dependability.
• Low-Profile 288-Pin DIMM Form Factor: Designed to fit standard DDR4 server motherboard slots across leading OEM platforms including Dell PowerEdge, HPE ProLiant, Lenovo ThinkSystem, Supermicro, and Fujitsu PRIMERGY server families.
• Optimised Power Efficiency: Operating at 1.2V, the DDR4 architecture consumes significantly less power than DDR3-based equivalents at comparable speeds, reducing total cost of ownership and cooling requirements in high-density rack deployments.

Technical Architecture

At its core, the Samsung 128GB DDR4-3200 ECC RDIMM is built on a multi-die stacking architecture, utilising Samsung's proprietary high-density DRAM packaging technology. The module features 288 pins conforming to the JEDEC DDR4 RDIMM standard and operates across a dual-rank or quad-rank configuration (depending on specific Samsung model variant), allowing memory controllers to interleave access across multiple ranks for improved sustained bandwidth.

The registered (buffered) design incorporates a Register Clock Driver (RCD) chip that re-drives command, address, and clock signals from the memory controller to the DRAM arrays. This buffering reduces the electrical load on the host memory controller, enabling the use of larger DIMMs and more modules per channel than unbuffered (UDIMM) designs would allow. This is why RDIMMs are the standard choice for enterprise server platforms that support 4–8 DIMMs per channel.

ECC functionality is implemented through additional parity bits stored alongside data bits. The ECC logic can transparently detect and correct single-bit errors (SECDED — Single Error Correction, Double Error Detection), ensuring that transient bit flips caused by cosmic ray interference, electrical noise, or manufacturing variability do not result in data corruption or unplanned system downtime. For workloads operating on financial, medical, or legally sensitive data, ECC is not optional — it is essential.

The module's DDR4 interface operates with a burst length of 8 and supports bank groups for improved command scheduling efficiency, contributing to higher effective bandwidth utilisation compared to DDR3 at similar clock rates. CAS latency characteristics at DDR4-3200 are optimised for server-class workload profiles, balancing throughput and access latency for both sequential and random memory access patterns.

Performance & Capacity

With a rated speed of DDR4-3200 (also denoted as PC4-25600), each module delivers a theoretical peak memory bandwidth of 25,600 MB/s. In a dual-channel configuration, this scales to approximately 51.2 GB/s of combined bandwidth — and in a quad-channel or octa-channel server platform (such as those based on Intel Xeon Scalable or AMD EPYC processors), total system memory bandwidth can reach hundreds of gigabytes per second when multiple modules are installed.

The 128GB capacity per DIMM makes it possible to populate a dual-socket server with 8 DIMMs and achieve 1TB of total system RAM — a configuration that was once reserved for purpose-built appliances but is now achievable on standard 2U rack servers. This level of memory capacity is transformative for workloads such as SAP HANA, Redis, Apache Spark, and large language model (LLM) inference tasks that benefit enormously from keeping entire datasets resident in DRAM rather than spilling to NVMe or SSD storage.

Real-world sustained memory bandwidth in typical server platforms running STREAM benchmark workloads ranges from 18,000 to 22,000 MB/s per module, depending on processor architecture, memory controller configuration, and the number of populated channels. Latency figures for DDR4-3200 at CL22 are approximately 13.75 nanoseconds of true latency — competitive within the DDR4 generation and well-suited for mixed read/write enterprise application profiles.

• In-Memory Databases (SAP HANA, Redis, VoltDB, MemSQL): In-memory computing platforms require terabytes of low-latency DRAM. Populating servers with 128GB RDIMMs is the most efficient path to achieving the required memory footprint.
• High-Performance Computing (HPC) and Scientific Simulation: Computational fluid dynamics, weather modelling, genomics, and finite element analysis all generate massive working datasets that must reside entirely in DRAM for acceptable performance.
• Big Data Analytics (Apache Spark, Hadoop, Presto): Distributed analytics frameworks perform dramatically better when shuffle data and intermediate computation results can be stored in memory rather than written to disk.
• Oracle Database and SQL Server In-Memory OLTP: Mission-critical relational databases leveraging in-memory table extensions and buffer pools require abundant, fast, and error-free DRAM to deliver sub-millisecond query response times.
• Cloud and Hosting Provider Infrastructure: Managed service providers, IaaS cloud operators, and colocation hosting companies require high-density, cost-effective memory solutions to maximise compute capacity per rack unit and deliver competitive VM instance pricing.
