Product Overview

The SK hynix 96GB DDR5-4800 ECC RDIMM is a flagship enterprise server memory module engineered for organisations that demand the highest levels of memory capacity, bandwidth, and reliability in a single DIMM slot. As data centre workloads continue to evolve — from in-memory databases and virtualised environments to large-scale AI and machine learning training — the need for high-density, high-speed memory has never been more critical. This module addresses that need directly, offering 96GB of capacity per slot at DDR5-4800 speeds with full ECC (Error-Correcting Code) protection and registered buffering (RDIMM), making it a premier choice for mission-critical deployments across enterprise IT, cloud service providers, high-performance computing (HPC) centres, and telecommunications infrastructure.

SK hynix is one of the world's leading semiconductor manufacturers, consistently recognised for exceptional DRAM quality, innovation in memory technology, and rigorous validation processes. The HMCGM4MEBRB233N module reflects that pedigree, delivering a product that is fully compliant with JEDEC DDR5 standards, designed for long-term operational stability, and validated for compatibility with leading server platforms from Intel and AMD. Whether you are scaling a virtualisation cluster, deploying a new SAP HANA node, or expanding an AI inference rack, this module delivers the performance headroom and reliability that enterprise applications demand.

Key Features & Benefits

• 96GB High-Density Capacity: Maximise memory per server by populating fewer slots while achieving extraordinary total system RAM — critical for workloads that benefit from large in-memory footprints, such as in-memory analytics and large language model inference.
• DDR5-4800 Speed: Operating at 4800 MT/s, this module delivers approximately 1.5× the bandwidth of DDR4-3200, significantly accelerating memory-bound workloads and reducing latency in data-intensive applications.
• ECC (Error-Correcting Code) Protection: On-die ECC combined with registered buffer ECC ensures that single-bit memory errors are automatically detected and corrected in real time, preserving data integrity and system uptime in 24/7 operational environments.
• RDIMM (Registered DIMM) Architecture: The registered buffer reduces electrical load on the memory controller, enabling support for higher DIMM counts per channel and improving signal integrity at high frequencies — essential for multi-socket server configurations.
• DDR5 Native Power Efficiency: DDR5 operates at 1.1V compared to DDR4's 1.2V, resulting in measurable reductions in power consumption per gigabyte — directly translating to lower TCO and reduced cooling requirements at scale.
• JEDEC DDR5 Standard Compliance: Full compliance ensures broad compatibility across certified Intel Xeon Scalable (Sapphire Rapids and beyond) and AMD EPYC (Genoa/Bergamo and beyond) server platforms without additional configuration overhead.
• On-Die ECC (ODECC): Built-in on-die error correction within the DRAM cells provides an additional layer of reliability at the silicon level, complementing the system-level ECC for a robust, multilayer data protection approach.
• Enterprise-Grade Build Quality: Manufactured in SK hynix's state-of-the-art fabs using leading-edge process nodes, each module undergoes rigorous qualification testing to meet the demanding reliability and longevity standards expected in enterprise and carrier-grade environments.

Technical Architecture

The HMCGM4MEBRB233N is based on SK hynix's advanced DDR5 DRAM die technology, leveraging a high-density monolithic or multi-die package configuration to achieve the 96GB capacity within a standard DIMM form factor. DDR5 introduces a fundamentally redesigned architecture compared to DDR4: the memory bus is split into two independent 32-bit sub-channels per DIMM (versus a single 64-bit channel in DDR4), effectively doubling the command and address bandwidth and improving parallelism for concurrent memory access requests.

The registered clock driver (RCD) on this RDIMM buffers the command, address, and control signals between the memory controller and the DRAM chips, reducing the fanout load and enabling stable operation at higher frequencies even with full memory channel population. DDR5 RDIMMs also integrate a power management IC (PMIC) directly on the module, shifting voltage regulation responsibilities from the motherboard to the DIMM itself — resulting in cleaner, more precise power delivery and improved signal quality.

ECC functionality operates at two levels: on-die ECC within each DRAM chip silently corrects single-bit errors before data is transferred off-chip, while the system-level ECC (SECDED — Single Error Correct, Double Error Detect) provides an additional layer across the full 72-bit data path (64-bit data + 8-bit ECC), ensuring that any errors that escape the on-die correction are caught and handled before reaching the processor or application layer.

Performance & Capacity

At DDR5-4800, each sub-channel delivers a peak theoretical bandwidth of approximately 38.4 GB/s, with the two sub-channels per DIMM combining to provide up to 76.8 GB/s of aggregate bandwidth per module under optimal conditions. In practical multi-channel server configurations — such as an 8-channel Intel Xeon Scalable platform fully populated with these 96GB RDIMMs — total system memory bandwidth can exceed 300 GB/s, a dramatic improvement over equivalent DDR4 configurations.

The 96GB capacity per module means that a dual-socket server with 16 DIMM slots can achieve up to 1.5TB of total system memory, enabling workloads such as SAP HANA, Oracle in-memory databases, and large-scale Kubernetes clusters to operate entirely in RAM with no reliance on slower storage tiers. For AI and machine learning inference workloads, the combination of high bandwidth and high capacity reduces data stall cycles and keeps GPU and CPU pipelines fully fed, directly improving throughput and reducing time-to-result for batch inference jobs.

The CAS latency profile at DDR5-4800 is optimised for enterprise use, balancing raw throughput with acceptable access latency for mixed read/write workloads typical in virtualised environments and OLTP databases. Memory power consumption at 1.1V operating voltage is significantly lower per-gigabyte than comparable DDR4 configurations, with the integrated PMIC further improving power delivery efficiency under varying load conditions.

• Enterprise Virtualisation & VDI: High-density memory reduces the number of physical servers required to host large virtual machine counts, directly lowering hardware acquisition costs and data centre footprint while improving VM density per rack.
• In-Memory Databases (SAP HANA, Oracle IMDB, Redis): Applications that rely on keeping entire datasets in RAM for sub-millisecond query response times benefit enormously from the combination of 96GB capacity and DDR5-4800 bandwidth.
• High-Performance Computing (HPC) & Scientific Simulation: Computational fluid dynamics, molecular dynamics, weather modelling, and financial risk simulation all benefit from the low-latency, high-bandwidth characteristics of DDR5 memory at maximum capacity per node.
• Cloud & Hyperscale Data Centres: Cloud service providers and hyperscalers building next-generation compute nodes can maximise workload density per server, improving revenue per rack and reducing power and cooling overhead at scale.
• OLAP & Data Warehousing: Analytical query engines such as ClickHouse, Snowflake on-premises deployments, and columnar databases leverage large in-memory datasets to accelerate complex aggregations and joins — use cases where 96GB per DIMM is a genuine operational advantage.
• Telecommunications & Edge NFV: Network function virtualisation (NFV) platforms and 5G core infrastructure require high-reliability, high-density memory to support large numbers of concurrent virtual network functions with deterministic latency and zero tolerance for memory errors.
