MTC40F2046S1RC64BD2R Crucial 1x64GB DDR5 RDIMM ECC RAM

High-Performance DDR5 RDIMM ECC Server Memory Module for Bandwidth-Driven Platforms with the MTC40F2046S1RC64BD2R

The MTC40F2046S1RC64BD2R is a 64GB DDR5 Registered DIMM engineered for DDR5-capable server platforms where predictable memory behavior and ECC protection are mandatory. Built as a JEDEC-compliant 288-pin RDIMM with a 72-bit data path, it is designed to integrate cleanly into modern CPU memory controllers and server BIOS policies without XMP/EXPO dependencies, supporting stable operation across validated configurations.

In contemporary virtualized and database-centric architectures, memory bandwidth and capacity scaling can be the dominant limiter rather than CPU core count. The MTC40F2046S1RC64BD2R operates at DDR5-6400 to increase per-channel throughput, while registered buffering enables higher DIMM loading and improved signal integrity in multi-slot server topologies. Dual-rank x4 organization supports efficient access patterns and RAS-oriented layouts, and ECC reduces the operational risk of soft errors under sustained load. The MTC40F2046S1RC64BD2R aligns well with PCIe Gen5 dense I/O systems by preventing memory bottlenecks that can starve high-speed storage and accelerator traffic.

Why Choose the MTC40F2046S1RC64BD2R?

The MTC40F2046S1RC64BD2R provides a straightforward path to higher memory density and bandwidth per node without changing the compute platform. For enterprises standardizing on validated DDR5 RDIMM ECC configurations, it supports consistent fleet behavior, scalable population across channels, and reliable uptime characteristics required for clustered deployments and mixed-production workloads.

Crucial focuses on server-grade memory engineering that prioritizes JEDEC adherence, signal integrity, and long-term platform compatibility. The result is a module profile aligned with contemporary data center requirements for controlled thermals, predictable training, and enterprise operational stability.
