This Micron 4GB DDR4-2400 RDIMM, featuring ECC and a registered signal type, is purpose-built for server platforms running virtualization or memory-intensive database workloads where data integrity is paramount. Its single-rank x8 configuration minimizes electrical loading on the memory bus, ensuring stable 1.2V operation at CL17 latency for consistent, reliable performance in dense deployments.
1. ECC protection silently detects and corrects single-bit errors, safeguarding transactional data integrity for mission-critical database and virtualization workloads.
2. Registered signal buffering stabilizes high-capacity memory configurations, enabling dense server deployments without compromising signal integrity or uptime.
3. Single-rank design reduces electrical loading on the memory channel, allowing consistent access latency even when multiple DIMMs populate the server board.
4. Modest module capacity provides isolated memory resources for dedicated lightweight containers or microservices, preventing noisy-neighbor interference in multi-tenant environments.
5. High clock speed combined with tight column access latency accelerates in-memory caching and analytics, reducing response times for latency-sensitive enterprise applications.
Designed for the data center, the Micron MTA9ASF51272PZ-2G3B1IK is a 4GB DDR4-2400 Registered DIMM that turns four critical engineering choices into tangible reliability and performance for server environments. Its ECC technology actively corrects single-bit memory errors, which is not a theoretical safeguard but a daily defense against cosmic-ray-induced bit flips that would otherwise silently corrupt financial transactions or patient records. The Registered signal buffer decouples the memory bus from the DRAM chips, enabling platforms to populate all channels with multiple modules without command-address instability—this is the foundation for scaling a VMware cluster to host dozens of virtual machines without sporadic crashes during peak loads. A single‑rank x8 organization balances latency and bandwidth, giving an in-memory database like Redis predictable, low‑latency throughput for millions of key‑lookup operations per second. Finally, the 1.2V operating voltage slashes power consumption per DIMM, which, when multiplied across a fully populated rack, means less cooling overhead and a lower total cost of ownership. In a virtualized cluster, these attributes together mean you deploy with confidence that a memory fault will not bring down multiple guests; in a read‑heavy database tier, ECC and clean signal integrity ensure that every query returns the truth, not a phantom bit.
General Virtualization
To support typical hypervisor workloads, populate all memory channels symmetrically with one or two 4 GB RDIMMs per channel. This ensures balanced memory bandwidth and ECC resilience. A 16-slot dual-socket server achieves 64 GB to 128 GB, sufficient for dozens of light VMs. Avoid mixing ranks asymmetrically to prevent NUMA penalties.
In-Memory Database
In-memory databases require maximal capacity and fault tolerance. Deploy fully populated configurations—24 to 32 DIMMs per socket—to reach 96–128 GB per node with these 4 GB modules. Where capacity demands exceed 256 GB, consider higher-density modules, but these registered ECC DIMMs still suit small-to-mid-size Redis or Memcached instances with data persistence. Always populate in matched sets for mirroring.
High-Performance Computing
HPC favors bandwidth over sheer capacity. Use a single 4 GB DIMM per memory channel on each socket to saturate the memory bus; an 8-channel platform yields 32 GB per node, ideal for bandwidth-bound simulations. Scale to two DIMMs per channel (64 GB) only if the workload’s working set grows, but watch for speed drops at higher loads. ECC guards against silent data corruption during long runtimes.

Q: Can I mix this MTA9ASF51272PZ-2G3B1IK with other memory modules of different brands or speeds?
A: Mixing with different brands or speeds is not recommended for registered ECC memory. It may cause instability or failure to POST. Always use identical Micron modules with the same part number and rank for guaranteed compatibility.
Q: Is this memory compatible with my system?
A: This 4GB DDR4-2400 RDIMM is compatible with servers using Intel Xeon E5-2600 v3/v4, Scalable, or AMD EPYC platforms that support registered ECC memory. Verify your motherboard supports 288-pin RDIMMs.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server vendor’s memory population guidelines. Typically, populate identical DIMMs per channel, starting with the farthest slots from the CPU. Balance capacity across memory channels for optimal bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant registered server DIMM designed for reliability at standard speeds. It does not support overclocking or XMP profiles. Operation at DDR4-2400 with CL17 is guaranteed.
Q: What warranty and typical failure rate can I expect?
A: This Micron module comes with a 1-year warranty. Typical annualized failure rate (AFR) for enterprise RDIMMs is less than 0.5% under standard operating conditions, reflecting high reliability for server workloads.
