Product Overview

The Micron DDR5 RDIMM 96GB 2Rx8 6400MT/s CL52 (V5CB) Tray module represents the cutting edge of enterprise server memory technology. Engineered by Micron — one of the world's leading semiconductor manufacturers — this registered dual in-line memory module delivers an exceptional combination of capacity, speed, and reliability for mission-critical computing environments. With a 96GB capacity per module, a blazing 6400MT/s data transfer rate, and CL52 timing, this DDR5 RDIMM is purpose-built for modern data centres, AI inference and training platforms, high-performance computing (HPC) clusters, and cloud-native infrastructure deployments.

DDR5 represents the most significant generational leap in DRAM technology in over a decade. Compared to DDR4, DDR5 effectively doubles the per-pin bandwidth, integrates on-die ECC for improved signal integrity, and introduces a dual-channel architecture within a single DIMM slot — all of which translate directly into measurable real-world gains for workload-intensive enterprise applications. The 2Rx8 configuration (dual rank, x8 organisation) optimises interleaving performance and makes this module an ideal choice for platforms demanding high memory throughput alongside enterprise-grade reliability.

Offered in tray format, this module is ideal for system integrators, OEM builders, hyperscalers, and enterprise IT procurement teams sourcing memory at volume for server builds or infrastructure refresh cycles. Each module ships brand new and direct from authorised stock, ensuring full authenticity and compatibility assurance.

Key Features & Benefits

• 96GB Density per Module: Enables extremely high memory-per-socket configurations, reducing the number of DIMMs required to populate a server and lowering total power consumption per gigabyte.
• 6400MT/s Data Rate: Delivers outstanding memory bandwidth that directly accelerates data-intensive applications including AI/ML model training, database transactions, and in-memory analytics.
• CL52 Latency: Optimised CAS latency tuned for the 6400MT/s speed grade, balancing access timing with raw throughput for real-world server workloads.
• 2Rx8 Dual-Rank Architecture: The dual-rank, x8 bit-width organisation enhances memory interleaving efficiency, improving effective bandwidth utilisation in multi-DIMM configurations.
• Registered (RDIMM) Design: The register component buffers the command and address signals between the memory controller and the DRAM dies, enabling stable operation in high-density configurations and reducing electrical load on the CPU memory controller.
• On-Die ECC (ODECC): DDR5 natively incorporates on-die error correction on each DRAM device, improving data integrity at the silicon level before signals even reach the system-level ECC layer.
• System-Level ECC Support: Fully compatible with ECC-enabled platforms, providing an additional layer of error detection and correction critical for enterprise uptime and data integrity requirements.
• Tray Packaging: Supplied in bulk tray format without retail packaging, making it cost-effective and logistics-efficient for large-scale deployments, system builds, and OEM integration workflows.
• Micron V5CB Silicon: Built on Micron's advanced DRAM fabrication process (V5CB die revision), ensuring consistent yield, binned performance characteristics, and long-term supply reliability.

Technical Architecture

The MTC40F204W51RC64BC1 is built on the JEDEC DDR5 standard, leveraging a fundamentally redesigned electrical and logical architecture compared to its DDR4 predecessor. DDR5 modules operate at a reduced voltage of 1.1V (compared to DDR4's 1.2V), improving energy efficiency at scale. The on-module voltage regulator (PMIC — Power Management IC) is integrated directly onto the DIMM PCB, offloading power regulation from the motherboard and enabling more precise, stable voltage delivery to the DRAM devices.

The 2Rx8 topology means the module contains two independent ranks of DRAM, each composed of x8 (8-bit wide) DRAM packages arranged in a 64-bit wide data bus per rank. This configuration supports rank interleaving at the memory controller level, allowing the CPU to pipeline memory accesses across both ranks simultaneously — effectively hiding access latency and increasing sustained bandwidth. With 96GB of total capacity, this is achieved through high-density 16Gb (2GB) DRAM die stacking or large-die configurations within each package, depending on the specific die revision deployed in the V5CB build.

The registered buffer (RCD — Registering Clock Driver) on this RDIMM re-drives the command, address, and control signals, isolating the memory controller from the electrical load of multiple DRAM chips. This is essential in multi-DIMM-per-channel (MDPC) configurations and in servers with high DIMM slot counts, where signal integrity would otherwise degrade at high speeds. The result is that 6400MT/s operation remains stable even in fully populated memory configurations across dual- and quad-socket platforms.

Performance & Capacity

At 6400MT/s, this DDR5 RDIMM delivers a theoretical peak bandwidth of approximately 51.2 GB/s per channel. In a dual-channel CPU configuration (common in modern server sockets), two modules can collectively provide up to 102.4 GB/s of memory bandwidth per socket — a figure that directly benefits large language model (LLM) inference, OLAP query engines, and real-time streaming analytics platforms where data movement between compute and memory is the primary performance bottleneck.

With 96GB per module, a typical 2-socket server with 24 DIMM slots (12 per socket) can be fully populated to deliver 2.304TB of DDR5 memory — enabling in-memory datasets of extraordinary scale without relying on slower NVMe or storage tiers. For platforms with 8 DIMM slots per socket, a single-socket system can achieve 768GB, sufficient for most enterprise database and virtualisation workloads.

Latency at CL52 with a 6400MT/s data rate results in an absolute latency of approximately 16.25 nanoseconds — competitive with high-speed DDR4 modules operating at lower absolute clock speeds, while delivering substantially greater bandwidth. This makes the module well-suited for latency-sensitive workloads such as financial trading systems, real-time fraud detection engines, and high-frequency transactional databases.

Compatibility & Integration

This module is compatible with server platforms based on Intel Xeon Scalable (Sapphire Rapids and Emerald Rapids) and AMD EPYC (Genoa, Bergamo, and Siena) processors — all of which natively support DDR5 memory channels. It adheres to JEDEC JESD79-5 DDR5 standards, ensuring broad platform interoperability across major server OEMs including HPE ProLiant Gen11, Dell PowerEdge 16th Generation, Lenovo ThinkSystem V3, Supermicro X13 series, and Gigabyte server platforms.

The module is compatible with Linux (RHEL, Ubuntu, SUSE), Windows Server 2022 and later, VMware vSphere 8.x, and all major hypervisor and container orchestration platforms. As a JEDEC-standard RDIMM, it does not require proprietary firmware or platform-specific configuration beyond standard BIOS memory training sequences. ECC functionality is automatically enabled on ECC-capable platforms.

Ideal Use Cases

• AI & Machine Learning Training: Large transformer model training workloads require massive memory bandwidth to feed GPU compute pipelines. High-capacity DDR5 RDIMMs reduce memory bottlenecks in CPU-GPU hybrid training nodes and CPU-only inference servers.
• In-Memory Databases & OLAP: Platforms such as SAP HANA, Oracle TimesTen, Redis, and ClickHouse benefit enormously from 96GB modules enabling terabyte-scale in-memory datasets with sub-millisecond query response times.
• High-Density Server Virtualisation: VMware vSphere, Microsoft Hyper-V, and KVM environments running hundreds of virtual machines per host require maximum per-socket memory. 96GB DIMMs dramatically increase VM density without adding physical servers.
• HPC & Scientific Computing: Computational fluid dynamics, genomics pipelines, weather modelling, and molecular simulation workloads are memory-bandwidth-bound. DDR5 at 6400MT/s provides the throughput these applications require.
• Cloud & Hyperscale Infrastructure: Hyperscalers and private cloud operators deploying at scale benefit from the tray format, high density, and consistent Micron binning quality to maintain predictable performance across large server fleets.
• Real-Time Analytics & Financial Services: Trading platforms, fraud detection engines, and real-time risk calculation systems demand both low latency and high bandwidth — characteristics this module delivers at enterprise scale.
• Containerised & Microservices Architectures: Kubernetes clusters and container runtimes benefit from higher per-node memory availability, reducing pod eviction rates and enabling larger container memory limits per node.
