This 64 GB DDR5-4800 Registered ECC DIMM is purpose-built for enterprise servers and demanding workloads such as virtualization and in-memory databases, where its hardware error correction and registered signal buffering deliver uncompromised data integrity and bank-level stability under heavy load. The module’s 1.1 V low-voltage operation and CL40 latency further optimize power efficiency and thermal performance in dense, mission-critical deployments.
1. A 64 GB dense module allows servers to host more virtual machines and larger in-memory databases per node, directly raising consolidation ratios without compromising responsiveness.
2. DDR5 technology elevates delivered memory bandwidth to keep multiple CPU cores saturated, accelerating throughput for real-time analytics and large-scale enterprise workloads.
3. Integrated ECC proactively detects and corrects data errors, eliminating silent corruption and safeguarding financial, scientific, and mission-critical database transactions.
4. The registered buffer architecture stabilizes signal integrity across high-capacity DIMM populations, enabling reliable operation in fully loaded server boards under 24/7 uptime demands.
5. A 4800 MT/s transfer rate supplies the sustained data conduit required by heavy virtualization I/O and AI inference engines, shrinking latency for time-sensitive processing.
The Micron MTC40F2046S1RC48BA1A is a server-grade DDR5 memory module engineered for mission-critical enterprise environments, where every bit of data integrity and system uptime counts. Its four defining characteristics directly address the real-world pain points of IT infrastructure managers. First, the 64 GB capacity per DIMM allows you to provision significantly more virtual machines per physical host, reducing server sprawl and optimizing your VMware vSphere or Proxmox cluster density. Second, the onboard ECC technology continuously detects and corrects single-bit memory errors caused by cosmic radiation or electrical noise, which is non-negotiable for financial transaction databases and in-memory analytics platforms like SAP HANA, where silent data corruption can lead to cascading financial discrepancies and unplanned downtime. Third, the Registered signal buffer stabilizes the command and address lines when populating multiple DIMMs per channel, enabling you to scale to 2 TB or more of system memory across 16 or 24 slots without signal degradation, a genuine concern during heavy multi-tenant workloads. Fourth, the DDR5-4800 speed and dual 40-bit sub-channel architecture deliver breakthrough bandwidth for large dataset processing, ensuring your Redis or Memcached layers respond with consistent sub-millisecond latency even under peak load. In essence, this module transforms your server platform into a resilient, high-density, and high-throughput compute node where data fidelity and performance scale in lockstep.
General Virtualization
This 64GB DDR5-4800 Registered ECC DIMM is ideal for dense virtualization hosts. A single module allows you to start with moderate capacity and scale by populating additional channels later. For balanced performance in dual-socket systems, deploy at least one DIMM per memory channel—typically eight identical modules—to maximize bandwidth and avoid NUMA penalties.
In-Memory Database
In-memory databases demand both capacity and data integrity, making registered ECC mandatory. With 64GB sticks, you can reach 512GB or 1TB in an 8- or 16-slot server while maintaining low-latency CL40 timings. Always configure identical modules across channels to sustain the throughput required for Redis, Memcached, or SAP HANA workloads.
High-Performance Computing (HPC)
HPC clusters benefit from the reliability of registered ECC and the bandwidth of DDR5-4800. Populate all memory channels evenly to feed vectorized CPU instructions without bottlenecks. For memory-bandwidth-bound simulations, a fully balanced configuration of eight or twelve 64GB modules delivers both massive capacity and the consistent speed necessary for MPI-based parallel jobs.

Q: Can I mix this MTC40F2046S1RC48BA1A with other memory modules of different brands or speeds?
A: Mixing is not recommended for server environments. Differing SPDs or ranks may cause instability. For mission‑critical platforms, use identical modules validated together to maintain signal integrity and guaranteed uptime.
Q: Is this memory compatible with my system?
A: This 64GB DDR5-4800 Registered ECC DIMM is designed for dual‑socket Intel Xeon Scalable and AMD EPYC 9004/8004 platforms. Verify your server board’s QVL list and ensure DDR5 RDIMM support before purchase.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your motherboard manual's balanced‑channel population. Typically, install matched pairs starting with slots farthest from the CPU, filling symmetrical channels to maximize memory interleaving and bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC‑compliant server module. Registered ECC memory prioritizes data integrity and stability over overclocking. XMP profiles are not supported; the module runs at standard DDR5-4800 CL40 timings.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one‑year warranty. Built to JEDEC standards with stringent screening, its typical failure rate is extremely low, earning an annualized AFR well under 1% in properly cooled server environments.
