This 64GB DDR5-4800 Registered ECC RDIMM is engineered for enterprise servers and high-density compute platforms, making it ideal for memory-intensive workloads such as virtualization, large-scale in-memory databases, and mission-critical applications that demand uncompromising data integrity. Its dual-rank x4 organization and registered signal architecture enhance signal stability and channel utilization under heavy loads, while ECC ensures single-bit error correction for robust 24/7 reliability.
1. ECC error correction rigorously protects data integrity, essential for preventing costly silent errors in transactional databases and financial processing.
2. Registered signal buffering ensures electrical stability across densely populated server boards, enabling reliable operation with fully loaded memory channels in large-scale virtualization hosts.
3. 64GB per DIMM dramatically increases memory capacity per server node, allowing higher virtual machine density and smoother consolidation without compromising performance.
4. DDR5 technology boosts memory bandwidth and energy efficiency, directly accelerating throughput for AI training pipelines and memory-hungry analytics workloads.
5. Dual Rank x4 organization sustains peak channel utilization through rank interleaving, giving latency-sensitive enterprise applications predictable responsiveness under heavy concurrent access.
The MTC40F2046S1RC48BR server-grade DDR5 RDIMM addresses critical data center demands. Its ECC technology continuously corrects memory errors caused by background radiation, which is non-negotiable when a flipped bit could crash your in-memory database like SAP HANA or corrupt a financial transaction. The registered signal buffering stabilizes this 64GB module under heavy loads, allowing you to populate multiple DIMMs per channel in a dense virtualization cluster without signal integrity degradation—keeping hundreds of VMs responsive. Moreover, the dual-rank x4 design enables rank interleaving that boosts effective bandwidth; during periods of simultaneous VM migration and large-scale database queries, that extra throughput reduces latency and prevents bottlenecks. With 64GB of DDR5 running at 4800MT/s, you gain the capacity to house expansive Redis datasets or entire virtual desktop pools in RAM, accelerating real-time analytics while the 1.1V low-power operation helps rein in energy costs in always-on deployments. This is the reliability and headroom your enterprise infrastructure demands.
General Virtualization
For a dual-socket server with eight channels per CPU, deploy one 64GB DDR5-4800 ECC RDIMM per channel (16 modules) to achieve 1TB of balanced capacity. Keeping 1DPC maintains the full 4800MT/s speed and ensures end-to-end data integrity. For lighter consolidation, eight modules (512GB) on a single CPU still offers strong headroom.
In-Memory Database
Maximizing capacity is critical for in-memory platforms. Populate two 64GB RDIMMs per channel (2DPC) across both CPUs — 32 modules yield 2TB to house entire datasets in RAM. Expect speed to step down to DDR5-4400, but the massive density and registered ECC protection far outweigh the bandwidth trade-off.
High-Performance Computing (HPC)
HPC workloads demand peak bandwidth and low latency. Install one 64GB DIMM per channel to sustain 4800MT/s and avoid 2DPC penalties. An 8-channel node with 8 modules (512GB) or a 16-channel dual-socket node with 16 modules (1TB) delivers optimal throughput for simulation and modeling. If more capacity is required, move to higher-density DIMMs rather than populating a second DIMM per channel.

Q: Can I mix this MTC40F2046S1RC48BR with other memory modules of different brands or speeds?
A: Mixing registered ECC modules from different brands or with different speeds is not recommended. It may cause instability, reduced speed, or system boot failure. For guaranteed performance, use identical modules across all channels.
Q: Is this memory compatible with my Intel Xeon or AMD EPYC server platform?
A: This DDR5-4800 RDIMM is compatible with servers based on Intel Xeon Scalable (4th Gen+) and AMD EPYC 9004 Series processors. Verify that your motherboard supports registered ECC DDR5 and 4800 MT/s speed.
Q: What is the recommended DIMM population order for optimal performance?
A: Balance capacity evenly across memory channels. Typically populate 1 DIMM per channel first, then fill symmetrically. Consult your server board manual for exact slot ordering to optimize interleaving and maintain rated 4800 MT/s speed.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a server-grade registered ECC module built to JEDEC DDR5-4800 standards. It does not implement XMP or overclocking profiles, prioritizing data integrity and stability over frequency tuning.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Enterprise DDR5 RDIMMs have an annualized failure rate (AFR) typically below 0.4% under specified operating conditions, ensuring strong long-term reliability in 24/7 server environments.
