Crucial 32GB DDR5-5600 RDIMM ECC Registered

The Crucial CT32G56C46R2 is a 32GB DDR5-5600 Registered ECC DIMM (RDIMM) engineered for server and workstation platforms that demand high memory bandwidth, expanded capacity, and enhanced data integrity. Built on DDR5 architecture, this module operates at 5600 MT/s with on-die ECC and registered command/address buffering, enabling stable operation at elevated speeds across multi-DIMM configurations. The CL46 primary latency and 1.1V operating voltage reflect DDR5's efficiency-forward design compared to prior generations, making it well-suited for compute-dense environments where thermal and power budgets are tightly managed.

As an RDIMM, the CT32G56C46R2 incorporates a register (RCD) on the command and address bus, reducing electrical load on the memory controller and allowing more DIMMs per channel than unbuffered alternatives. This is particularly valuable in server platforms built on Intel Xeon (Sapphire Rapids and successors) or AMD EPYC (Genoa and successors) that expose DDR5 memory channels natively. The module's ECC capability detects and corrects single-bit errors while detecting multi-bit errors, a foundational requirement for enterprise uptime expectations in production server deployments.

Crucial positions this DIMM within its server memory portfolio targeting small-to-medium business infrastructure, edge compute nodes, and departmental server refreshes where DDR5-5600 platform compatibility is required. The 32GB capacity per module strikes a practical balance between per-slot density and per-server total memory scalability, supporting configurations from moderate-memory application servers up to memory-intensive analytical or virtualization workloads when populated across available DIMM slots.

Ideal for

• Virtualization hosts running VMware vSphere or Microsoft Hyper-V where multiple VMs require reliable, error-corrected memory pools at scale
• Edge data-center servers handling real-time analytics or inference workloads that benefit from DDR5's higher bandwidth relative to DDR4 platforms
• Database servers running MySQL, PostgreSQL, or Microsoft SQL Server where ECC protection reduces risk of silent data corruption in large working datasets
• SMB file and application servers being refreshed onto DDR5 platforms requiring registered DIMMs to meet multi-DIMM-per-channel stability requirements
• High-performance computing (HPC) nodes in departmental clusters where memory bandwidth is a primary constraint for scientific or engineering simulation workloads
• Containerized microservices infrastructure on Kubernetes clusters where per-node memory density expansion reduces total server count while maintaining ECC reliability
