MTC20F1045S1RC64BD2R

High-Performance DDR5 RDIMM Server Memory Module with ECC RAS architecture using the MTC20F1045S1RC64BD2R

The MTC20F1045S1RC64BD2R is a Crucial 32GB DDR5 RDIMM designed for enterprise server platforms that require deterministic memory behavior under sustained multi-core CPU loads. By combining Registered ECC operation with a single-rank x4 (72-bit) data path, the module supports stable scaling on modern CPU generations where memory bandwidth, queue depth, and error containment directly influence virtualization density and database latency.

Built to JEDEC DDR5-6400 (PC5-51200R) at 1.1V, MTC20F1045S1RC64BD2R complements PCIe 5.0/4.0 expansion and NVMe storage topologies by removing memory as a bottleneck for I/O-driven workloads. In balanced systems, the additional capacity enables larger page caches, higher VM consolidation, and reduced spill to storage, while ECC and RDIMM buffering improve signal integrity and reliability as DIMM counts increase across channels.

Why Choose the MTC20F1045S1RC64BD2R?

The MTC20F1045S1RC64BD2R delivers a pragmatic density-to-performance profile for production clusters where uptime and predictable scaling matter more than transient benchmarks. It is suited to standardized server builds that must expand memory without changing platform architecture, supporting consistent provisioning, controlled growth, and lower operational risk across distributed deployments.

Crucial focuses on disciplined DRAM qualification, adherence to JEDEC electrical specifications, and compatibility-oriented engineering to align with modern data centre reliability expectations. This approach supports long service lifecycles, repeatable fleet maintenance, and integration into enterprise change-control processes.

Key Applications:

Server memory expansion
Virtualization hosts
Database memory scaling
ECC-protected datacenter workloads
Private cloud consolidation
