This Micron 64GB DDR5-5600 Registered DIMM, with its ECC and 1.1V operation, is purpose-built for enterprise servers handling memory-intensive workloads such as virtualization and in-memory databases, where registered signaling ensures stable operation across densely populated memory channels. The module’s 2Rx8 organization (as implied by its part number MTC40F2046S1RC56BD1R) provides a balance of capacity and rank interleaving performance, while ECC hardens data integrity in 24/7 mission-critical environments.
1. A large 64 GB module footprint allows dense memory configurations, enabling aggressive server virtualization and smooth operation of memory-hungry in-memory databases without sacrificing host count.
2. Next-generation DDR5 technology doubles the internal bank groups, delivering substantially higher sustained bandwidth that prevents stalls in real-time analytics and AI inference pipelines.
3. The high 5600 MT/s transfer rate shrinks data access latencies, directly accelerating transactional throughput and response times in latency-sensitive financial or telecom workloads.
4. On-die ECC and side-band ECC work in concert to detect and correct both internal and external bit errors, preserving data integrity for long-running mission-critical applications and reducing silent data corruption risks.
5. Registered clock and command buffering stabilizes high-capacity DIMMs under fully populated channels, ensuring consistent uptime and reliable memory signaling even as core counts and module counts scale in dense rack servers.
Built as a registered server memory module, the MTC40F2046S1RC56BD1R leverages 64GB capacity, ECC, Registered buffering, and 5600MT/s bandwidth to address data center pain points. In dense virtualization clusters, Registered buffering stabilizes electrical loads across fully populated memory channels, letting you maximize VM density without signal instability or crashes. ECC continuously corrects single-bit errors from background radiation, preventing silent data corruption in transactional databases and VM state files—this means ultimate data integrity and zero unplanned downtime from memory faults. The 64GB per DIMM capacity enables building servers with multiple terabytes of RAM, essential for in-memory databases like SAP HANA or Redis to hold entire working sets for real-time processing. Paired with 5600MT/s speed, query latency drops sharply, so critical business analytics and financial transactions execute with uncompromised responsiveness.
General Virtualization
For dense virtualization hosts, this 64 GB Registered ECC DDR5 module allows you to build high-capacity, reliable memory pools. Install six to eight such modules in a dual-socket server to comfortably run 100+ lightweight VMs, while ECC corrects single-bit errors and Registered logic maintains signal integrity across large DIMM counts. Prioritize balanced memory across all memory channels to maximize throughput, and avoid mixing capacities to prevent NUMA imbalances.
In-Memory Database
In-memory databases demand both capacity and data integrity, making this RDIMM a strong fit. Deploy a fully-populated configuration—typically 16 modules across 16 DIMM slots—to reach 1 TB of RAM for Redis or SAP HANA workloads. The ECC feature prevents silent data corruption, and the 5600 MT/s speed delivers the low latency needed for real-time analytics. Always configure memory mirroring or sparing if absolute uptime is critical.
High-Performance Computing (HPC)
For HPC clusters running MPI-based simulations or AI training, populate all eight memory channels per CPU socket with these modules to achieve optimal bandwidth. A four-socket node with 32 DIMMs yields 2 TB of ECC-protected capacity, ideal for large datasets. The Registered architecture stabilizes multi-rank signaling in high-density deployments, while choosing 1 DIMM per channel (1DPC) at 5600 MT/s ensures peak frequency under load.
Rigorously tested, compatible with Dell PowerEdge R760, HPE ProLiant DL380 Gen11, Lenovo ThinkSystem SR650 V3.
Q: Can I mix this MTC40F2046S1RC56BD1R with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is not recommended. The server’s memory controller will downclock all modules to the slowest common speed, and mismatched ranks or timings may cause POST failures or stability issues.
Q: Is this memory compatible with my Intel Xeon or AMD EPYC server platform?
A: This 64GB DDR5-5600 RDIMM is compatible with platforms supporting DDR5 Registered DIMMs, such as 4th Gen Intel Xeon Scalable (Sapphire Rapids) and AMD EPYC 9004 series. Verify your server board’s QVL for this specific part.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server motherboard’s population guide. Generally, populate 1 DIMM per channel (1DPC) starting with the farthest slot from the CPU. Balanced configurations across all memory channels ensure maximum bandwidth and interleaving.
Q: Does this RDIMM support overclocking or XMP profiles?
A: No. As an enterprise-grade registered DIMM, it adheres strictly to JEDEC DDR5-5600 CL46 standards at 1.1V. Overclocking and XMP are not supported; stability and data integrity take priority in server environments.
Q: What warranty and typical failure rate can I expect for this Micron module?
A: It carries a 1-year warranty. Typical annualized failure rate (AFR) for Micron server memory is well below 0.5%, backed by rigorous screening and ECC error correction to ensure high reliability in 24/7 workloads.
