Micron DDR5-6400 96GB RDIMM 2Rx4 Server Memory

The Micron DDR5-6400 96GB RDIMM (MTC40F204WS1RC64BB) is a high-density registered dual in-line memory module engineered for the most demanding next-generation server platforms. Built on a 2Rx4 (dual-rank, x4 organization) architecture, it operates at DDR5-6400 (PC5-51200) speeds, delivering substantial bandwidth improvements over prior DDR4 generations. The module conforms to JEDEC DDR5 RDIMM standards and is designed to pair with Intel Xeon 6 (Granite Rapids) and AMD EPYC 9005 Series (Turin) processors, both of which feature native DDR5 memory controllers capable of exploiting the full throughput of this speed grade.

At 96GB per module, this RDIMM occupies a single DIMM slot while providing a density previously achievable only through costlier or less efficient configurations. The 2Rx4 topology balances rank-level parallelism with per-die data width to support high-capacity, high-reliability operation suitable for RAS-critical enterprise environments. The module incorporates on-die ECC (ODECC) inherent to DDR5 architecture, alongside the registered buffer that improves signal integrity across the memory bus, enabling stable operation in multi-DIMM-per-channel configurations at scale.

This module is specifically positioned for workloads that require very large in-memory datasets within a constrained physical slot count. Platforms built on Granite Rapids or Turin with support for high-density DIMMs can achieve per-socket memory capacities exceeding 1.5TB using 96GB RDIMMs across all available channels. Launched in Q4 2024, the MTC40F204WS1RC64BB represents Micron's current high-density RDIMM offering for mainstream enterprise server deployment, though procurement lead times reflect its status as a newly ramping, high-density product.

Ideal for

• In-memory database deployments (SAP HANA, Oracle In-Memory, Redis Enterprise) requiring multi-terabyte addressable memory per server node
• AI and machine learning inference servers where large model weights must reside entirely in DRAM to minimize latency
• Virtualization hosts running high VM densities under VMware vSphere or Red Hat OpenShift, where maximizing memory capacity per socket reduces physical server sprawl
• High-performance computing (HPC) workloads such as computational fluid dynamics or genomics pipelines that require large working-set memory with high bandwidth
• Cloud service provider infrastructure deploying next-generation Granite Rapids or Turin-based multi-tenant compute instances with memory-optimized SKUs
• Enterprise ERP and analytics platforms (SAP S/4HANA, Microsoft SQL Server) benefiting from expanded buffer pool sizes and reduced disk I/O through larger in-memory caches
