Micron DDR5 RDIMM 96GB 6400 MT/s

The Micron DDR5 RDIMM 96GB 6400 MT/s (MTC40F2046S1RC64BA1R) is a high-capacity registered dual in-line memory module engineered for the demands of modern enterprise servers, high-performance computing platforms, and AI/ML inference and training infrastructure. Built on DDR5 architecture, it operates at 6400 MT/s with a 64-bit wide data bus and incorporates on-die ECC (ODECC) alongside RCD (Registering Clock Driver) buffering to ensure signal integrity across high-density memory configurations. The 96GB capacity per module is achieved through advanced DRAM die stacking, enabling exceptional memory density per DIMM slot and reducing the number of slots required to populate large memory pools in dual- and quad-socket server platforms.

As a 1Rx4 or multi-rank registered module in the DDR5 generation, this DIMM supports the expanded voltage and power management improvements inherent to DDR5, including on-module power management integrated circuits (PMICs) that regulate voltage delivery locally on the DIMM, improving efficiency and reducing mainboard complexity. DDR5 RDIMMs at this speed grade are qualified against JEDEC standards and are compatible with platforms utilizing Intel Xeon Scalable (Sapphire Rapids and successors) and AMD EPYC (Genoa and successors) processors that support DDR5 memory channels. The module operates at 1.1V, consistent with DDR5 specifications, delivering improved energy efficiency relative to DDR4 at comparable capacities.

The MTC40F2046S1RC64BA1R is purpose-built for datacenter and cloud environments where per-socket memory capacity, bandwidth, and reliability are critical operational parameters. Workloads including in-memory databases, real-time analytics, large language model (LLM) inference, virtualized infrastructure with high VM density, and memory-bandwidth-sensitive HPC applications directly benefit from the combination of 96GB capacity and 6400 MT/s throughput. Micron's manufacturing and validation processes for this module class are aligned with enterprise-grade quality requirements, supporting deployment in mission-critical server environments operated by cloud service providers, hyperscalers, and enterprise IT organizations across EMEA and APAC regions.

Ideal for

• High-density virtualization hosts requiring maximum vRAM per socket to support large numbers of concurrent virtual machines without memory overcommit
• AI and machine learning inference servers where large model weights must reside entirely in system memory for low-latency real-time serving
• In-memory databases and real-time OLAP analytics platforms that depend on high aggregate memory capacity and bandwidth to eliminate storage I/O bottlenecks
• HPC cluster nodes running memory-bandwidth-intensive simulations in computational fluid dynamics, genomics, and financial risk modeling
• Datacenter consolidation initiatives where higher per-DIMM capacity reduces the total number of physical servers required to support existing workloads
• Cloud service provider infrastructure scaling out DDR5-based server fleets to meet growing demand for memory-optimized compute instances
