Micron 2Rx4 PC5-38400 DDR5 RDIMM - 64 GB - DDR5

Server performance bottlenecks often stem from memory constraints—insufficient capacity, slow data rates, or lack of error correction can cripple virtualization, database, and high-performance computing workloads. The Micron MTC40F2046S1RC48BA1 directly addresses these pain points with a 64GB DDR5 Registered DIMM engineered for enterprise reliability and throughput.

Who is it for

This module is built for IT administrators, data center managers, and system integrators deploying or upgrading rack servers, blade systems, and workstations that demand high memory density and data integrity. It is ideal for memory-intensive applications such as in-memory databases, virtualization clusters, AI/ML training, and real-time analytics.

Main features

• 64GB capacity in a single module, enabling up to 512GB per 8-slot server or 1TB per 16-slot system.
• DDR5-4800 speed (PC5-38400) delivers 38.4 GB/s peak bandwidth per module, a significant leap over DDR4.
• ECC (Error-Correcting Code) detects and corrects single-bit errors, preventing data corruption and system crashes.
• Registered (RDIMM) design with on-board registers reduces electrical load on the memory controller, allowing higher densities and stable operation.
• Dual-rank, x4 configuration (2Rx4) optimizes bank interleaving for improved performance under heavy load.
• Low 1.1V operating voltage reduces power consumption and heat generation compared to DDR4's 1.2V.
• On-Die ECC (ODECC) enhances internal data integrity, a key DDR5 feature.
• 288-pin standard DIMM form factor fits all DDR5-compatible server boards.
• JEDEC and RoHS compliant for assured compatibility and environmental safety.

Tips

Verify that your server's motherboard supports DDR5 RDIMMs and check the maximum memory speed supported by your CPU—some platforms may downclock to 4400 MT/s or 4000 MT/s depending on the processor. For optimal performance, install identical modules in matched sets across all memory channels. Always handle memory modules by the edges to avoid electrostatic discharge; use an anti-static wrist strap during installation.
