MTC40F2046S1RC64BR Micron 1x64GB DDR5 ECC RAM

High-Performance DDR5 RDIMM ECC Server Memory enabling bandwidth-focused scale-up with the MTC40F2046S1RC64BR

The MTC40F2046S1RC64BR is a 64GB Micron DDR5 RDIMM ECC module designed for modern server CPU platforms where memory bandwidth, signal integrity, and predictable behavior under load directly influence VM density and database latency. As a JEDEC-standard DDR5-6400 registered DIMM, it supports stable memory channel operation at scale, aligning with current-generation enterprise processors that depend on high-throughput DDR5 population for balanced core-to-memory performance.

With a registered architecture and ECC on a 72-bit data path, the MTC40F2046S1RC64BR reduces electrical loading per channel compared to unbuffered designs, enabling higher capacity footprints and improved platform-level reliability. The dual-rank organization supports efficient interleaving, while the 288-pin DDR5 DIMM form factor integrates cleanly into standard server memory topologies. For systems with heavy PCIe Gen5 I/O and fast storage tiers, this module helps keep the CPU feed rate aligned with NVMe and accelerator-driven data pipelines without introducing tuning complexity.

Why Choose the MTC40F2046S1RC64BR?

The MTC40F2046S1RC64BR provides a pragmatic density-to-performance step for enterprise nodes by combining 64GB capacity with DDR5-6400 throughput in a registered ECC profile optimized for 24/7 duty cycles. It scales consistently across multi-socket platforms, supports clean capacity planning per channel, and avoids overclocking dependencies by operating within JEDEC parameters for repeatable deployments.

Micron’s server memory engineering emphasizes validation depth, tight process control, and long-life supply alignment with data centre qualification cycles. This approach supports predictable interoperability, reliable error correction behavior, and compliance with contemporary platform requirements for DDR5 RDIMM infrastructures.
