MTC40F2046S1RC64BH1 Crucial 1x64GB DDR5 RDIMM ECC RAM

High-Density DDR5 RDIMM Server Memory Expansion featuring ECC Registered Architecture with the MTC40F2046S1RC64BH1

The MTC40F2046S1RC64BH1 is a 64GB Crucial DDR5 RDIMM engineered to scale modern CPU platforms where memory bandwidth, latency consistency, and error resilience directly determine host efficiency. Designed for enterprise rack and tower servers, it supports JEDEC DDR5-6400 operation to sustain higher core counts and consolidated virtualisation ratios while maintaining predictable behavior under sustained load.

Built as an ECC Registered DIMM, the MTC40F2046S1RC64BH1 strengthens signal integrity for populated memory channels and reduces controller loading compared to unbuffered modules, enabling more stable capacity growth per socket. Its dual-rank x4 (72-bit) organisation aligns with server-class memory controllers for balanced throughput and fault detection/correction, which is critical when PCIe Gen5 expansion, high-speed networking, and NVMe storage stacks drive continuous I/O and higher memory pressure. This makes the module a practical choice for capacity expansion in nodes where storage acceleration and faster PCIe fabrics must be matched by memory performance and reliability.

Why Choose the MTC40F2046S1RC64BH1?

The MTC40F2046S1RC64BH1 provides a strong density-to-performance profile for enterprises standardising on DDR5 RDIMM memory, combining 64GB capacity with ECC Registered operation for controlled scaling across fleets. It supports predictable rollouts in clustered environments by adhering to JEDEC server profiles, helping reduce integration risk and simplifying validation across server generations.

Crucial focuses on server-grade engineering discipline, emphasizing platform compatibility, consistent component selection, and reliability aligned with data centre operating standards. This approach supports repeatable deployment outcomes and long-term serviceability for production infrastructure.
