This DDR4-2400 RDIMM with ECC and a registered signal type is server memory, purpose-built for entry-level virtualization hosts and lightweight in-memory database applications where data integrity is non-negotiable. Its single-rank x8 configuration minimizes bus loading for stable multi-DIMM operation, while ECC and the registered interface jointly ensure reliable error correction under sustained 1.2 V operation.
1. ECC protection corrects single-bit errors and detects multi-bit failures, ensuring data integrity for mission-critical enterprise applications and virtualized workloads.
2. Registered signal buffering isolates the memory controller from excessive electrical loading, allowing high-density DIMM configurations essential for scaling virtual machine memory.
3. Single Rank x8 organization minimizes bus loading per channel, enabling fully populated server boards without sacrificing clock frequency or stability.
4. DDR4 technology provides an ultra-low 1.2V operating voltage and increased internal bandwidth, reducing datacenter energy costs while supporting modern multi-core server processors.
5. The 2400 MT/s transfer rate delivers sufficient memory bandwidth to feed dual-socket CPU architectures, sustaining throughput for database lookups and real-time analytics.
When you are building a virtualization cluster or running an in‑memory database, every memory transaction carries business risk. The Micron MTA9ASF51272PZ-2G3B1II is a registered DDR4‑2400 RDIMM engineered precisely for these scenarios, and its four defining characteristics translate directly into operational reliability.
First, ECC constantly detects and corrects single‑bit errors before they become silent data corruption. In a virtualized host hosting dozens of VMs, even one flipped bit can crash a critical workload or introduce financial miscalculation in a database like SAP HANA. Second, the registered signal type buffers the command and address lines, stabilizing the electrical load when multiple DIMMs populate a server. This means your mid‑range server can confidently scale to higher capacities without signal degradation, sustaining heavy consolidation ratios. Third, the 1.2 V low‑voltage design cuts power draw and thermal output across a rack of nodes, which directly lowers your cooling OPEX in colocation facilities. Finally, the single‑rank x8 configuration at 2400 MHz provides consistent bandwidth and low latency for concurrent access patterns. In a Redis cluster handling thousands of requests per second, this balanced rank architecture avoids bottlenecks that would otherwise stall real‑time analytics. It is not just memory—it is a safeguard for data integrity, stability at scale, and cost‑critical efficiency.
General Virtualization
For a mid-sized virtualization host running a dozen light VMs, populate six to eight of these 4 GB RDIMMs to build a 24–32 GB pool. Stick to balanced DIMM-per-channel configurations (e.g., one DIMM per channel in a dual-socket system) to maintain 2400 MHz speed and avoid memory bandwidth bottlenecks under mixed workloads.
In-Memory Database
In-Memory databases thrive on capacity and latency, so deploy the maximum supported modules on a platform with many DIMM slots—often 12 or 16 modules for 48–64 GB total. The registered ECC design ensures data integrity during high-throughput caching, and populating all channels symmetrically maximises throughput for real-time analytics.
High-Performance Computing (HPC)
HPC applications demand both bandwidth and reliability, so install six to eight modules (24–32 GB) per node, using one DIMM per channel for optimal 2400 MT/s operation. Dual-rank configurations would be preferable, but these single-rank 4 GB RDIMMs still suit compute-bound simulation jobs, while ECC protects long-running calculations from single-bit errors.

Q: Can I mix this MTA9ASF51272PZ-2G3B1II with other memory modules of different brands or speeds?
A: Mixing RDIMMs from different brands or speeds is not recommended. The system may default to the slowest common speed or fail to post due to signal integrity and ECC register-driven timing variations.
Q: Is this memory compatible with my Intel or AMD server platform?
A: This DDR4-2400 ECC Registered DIMM is compatible with dual-socket servers using Intel Xeon E5-2600 v3/v4 or AMD EPYC platforms that require 1.2V, 288-pin RDIMMs. Verify chipset support for registered memory.
Q: What is the recommended DIMM population order for optimal performance?
A: For optimal performance, populate identical RDIMMs per channel, starting from the furthest slot from the CPU. Follow the server motherboard's population guide to enable balanced memory interleaving and maximize bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-class ECC Registered DIMM, it runs at JEDEC standard DDR4-2400 CL17 only. Overclocking or XMP is not supported because system stability and data integrity are paramount in server environments.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year warranty. With a typical annualized failure rate below 0.5% for server-grade DRAM, it ensures reliable operation. Extended warranties are available upon request.
