Micron 96GB DDR5 6400MHz ECC Registered RDIMM 2Rx4 PC5-51200 Server Memory Module

Data centers and enterprise servers running memory-intensive workloads—virtualization, in-memory databases, AI/ML training—need reliable, high-capacity RAM that won't bottleneck performance. The Micron 96GB DDR5 6400MHz ECC Registered RDIMM (MTC40F204WS1RC64BR) delivers exactly that: a dual-rank x4 module engineered for next-gen server platforms. With a massive 96GB capacity, it doubles the density of typical 48GB modules, allowing more VMs per host and larger dataset caching. Operating at 6400 MT/s with a PC5-51200 rating, it provides a 50% bandwidth increase over DDR4-3200, while ECC and registered buffering ensure data integrity and signal stability under heavy load. Built to JEDEC standards, this module is a drop-in upgrade for compatible servers and workstations.

Key specifications

• Capacity: 96GB
• Memory type: DDR5
• Speed: 6400 MHz (PC5-51200)
• Form factor: 288-pin Registered DIMM (RDIMM)
• Rank configuration: 2Rx4 (dual rank, x4)
• ECC: Yes
• Voltage: 1.1V
• Application: Server / Workstation

Why choose it

This module is built for mission-critical environments where downtime is not an option. Registered buffering reduces electrical load on the memory controller, enabling higher densities and more DIMMs per channel. ECC detects and corrects single-bit errors, protecting against data corruption. The 2Rx4 organization balances performance and compatibility, and the 6400 MHz speed unlocks the full potential of DDR5 platforms. Micron's rigorous testing ensures long-term reliability and consistent performance.

Ideal use cases

• Virtualization hosts running multiple VMs per server
• In-memory databases (e.g., SAP HANA, Redis)
• AI/ML training and inference servers
• High-performance computing (HPC) clusters
• Enterprise resource planning (ERP) systems

Good to know

This RDIMM is JEDEC-compliant and compatible with DDR5 server platforms that support registered DIMMs. It operates at 1.1V, reducing power consumption compared to previous generations. The 288-pin design is standard for DDR5 RDIMMs, ensuring easy installation in compatible servers. Micron is a trusted manufacturer of memory for enterprise environments, and this module is backed by their quality assurance.
