Engineer's Note

This DDR5-4800 RDIMM with ECC and registered signaling is engineered for enterprise servers and memory-intensive workloads such as virtualization and in-memory databases, where the dual-rank x4 configuration boosts memory bandwidth and the integrated error correction ensures data integrity under sustained, mission-critical operation.

Technical Specs & Insights

1. 64 GB capacity per module maximizes memory density in server nodes, allowing heavier virtual machine consolidation and larger in-memory datasets without scale-out latency.
2. 4800 MHz speed provides the elevated DDR5 throughput required by multi-core server CPUs, eliminating data starvation in real-time analytics and transactional databases.
3. ECC protection silently corrects single-bit errors and detects multi-bit corruption, preserving data integrity through the months-long uptime demanded by mission-critical workloads.
4. Registered signal buffering stabilizes command and address lines across fully loaded memory channels, making large-footprint deployments reliable without sacrificing population capacity.
5. Dual Rank x4 organization combines rank interleaving for sustained bandwidth under heavy load with x4 DRAM width, enabling chipkill-class resilience that strengthens overall system uptime.

Why These Specs Matter

The MTC40F2046S1RC48BA1 is a 64GB DDR5 RDIMM purpose-built for modern server infrastructure, where every millisecond of latency and every bit of data integrity translates directly into business continuity. In a virtualized cluster running dozens of VMs, its ECC technology silently intercepts random bit flips triggered by background radiation at scale—errors that would otherwise corrupt a financial record or crash a hypervisor, costing hours of troubleshooting. The Registered signal type buffers the command bus so you can populate all channels with these high-density modules and maintain rock-solid signal stability, eliminating the memory-related reboots that plague dense virtualization hosts. For in-memory databases or real-time analytics, the dual-rank x4 design feeding 4800MHz bandwidth ensures that massive datasets are accessed in parallel, accelerating complex queries without a storage bottleneck. Meanwhile, the 1.1V low-voltage operation cuts thermal output across a rack of blazing-fast servers, directly reducing cooling overhead and extending the life of your deployment. This module means predictable performance and peace of mind for mission-critical workloads.

Endurance & Reliability

General Virtualization
Install one 64GB RDIMM per memory channel to maintain the full 4800 MT/s speed, delivering low latency and consistent performance for multiple virtual machines. A dual-socket server with eight channels per socket provides 1TB of capacity when fully populated with these modules, comfortably supporting 50 or more general-purpose VMs with room for growth.

In-Memory Database
Maximize capacity by fully populating all DIMM slots, even if using two DIMMs per channel reduces the speed to 4400 MT/s. A 24-slot server filled with these 64GB RDIMMs yields 1.5TB, allowing entire Redis or SAP HANA datasets to reside in RAM for near-instant response. Balance memory across all memory controllers to avoid controller bottlenecks.

High Performance Computing
For bandwidth-sensitive workloads, use a single 64GB module per channel to run at the full 4800 MT/s, giving 512GB per socket with peak throughput for floating-point and simulation tasks. If capacity is the primary constraint, populate two modules per channel to reach 1TB per socket, accepting a slight frequency drop. Benchmark the configuration to confirm that the capacity uplift outweighs any speed reduction for your specific HPC application.
