Designed as an unbuffered ECC UDIMM, this module is ideal for entry-level servers and professional workstations running virtualization or light database workloads, where the ECC error correction ensures critical data integrity. Its single-rank x8 configuration and CL15 latency at 2133 MHz deliver a balance of low command overhead and stable, power-efficient operation at just 1.2 V.
1. ECC error correction safeguards transactional data integrity, preventing silent memory corruption in always-on financial or database servers.
2. Unbuffered UDIMM design reduces memory access latency, beneficial for latency-sensitive edge compute and small-scale virtualization hosts.
3. DDR4 technology boosts data transfer efficiency, enabling higher throughput for concurrent users on web and application servers.
4. 2133MHz base clock provides balanced bandwidth for consistent service delivery in virtualized environments where memory overclocking is not desired.
5. 1.2V low operating voltage lowers power consumption per DIMM, cumulatively reducing energy costs and thermal load across dense server deployments.
When deploying a mission-critical microserver or a network-attached storage appliance, the Micron MTA9ASF51272AZ-2G1A1 memory module turns specifications into tangible uptime and efficiency. As a DDR4-2133 ECC Unbuffered DIMM, it is purpose-built for entry-level servers and workstations where data integrity cannot be compromised, yet full registered buffering is unnecessary. The true-error correction is the standout feature: in a ZFS-based NAS handling continuous file scrubbing or a lightweight virtualization host running several containers, a single bit-flip from background radiation can silently corrupt a checksum or crash a VM. ECC detects and corrects these errors in real time, meaning your family photos, business records, and containerized DNS services remain byte-perfect without fear of silent data degradation. The 1.2V operating voltage directly lowers thermal load inside compact 1U chassis or fanless industrial PCs, reducing power consumption across multiple modules and extending the lifespan of the voltage regulator modules. Meanwhile, the single-rank x8 organization at 2133MHz with a CAS latency of 15 provides consistent, predictable latency for caching and in-memory databases like Redis. This means stable query performance under concurrent access without the electrical loading penalties that registered memory introduces. It is not just a 4GB stick; it is a reliability upgrade that safeguards your silent workloads around the clock.
Based on its ECC, UDIMM and 288-pin specifications, this 4 GB module is classified as server memory. Capacity planning recommendations for typical server workloads are provided below.
General Virtualization
Populate four of these 4 GB ECC UDIMMs across available channels to create a reliable 16 GB footprint for hosting a small set of lightweight virtual machines. To handle moderately dense hypervisor workloads, install eight identical modules for a balanced 32 GB configuration that keeps ECC error correction active and guest states protected.
In-Memory Database
Maximize capacity by filling all DIMM slots with these ECC modules; a typical single-socket board accepts four or eight such UDIMMs, yielding 16 GB to 32 GB of fault-tolerant memory. While larger DIMMs are preferred in production, this approach offers a cost-effective starting point for development databases or small in-memory caching layers where data integrity is critical.
High-Performance Computing (HPC)
Configure every memory channel with identical modules to maximise bandwidth—for a quad-channel platform, install eight 4 GB ECC UDIMMs to achieve 32 GB of interleaved capacity. The single-rank x8 design helps reduce per-channel access latency in parallel computational workloads, and maintaining uniform DIMM populations across cluster nodes simplifies performance tuning and ensures consistent job throughput.
Rigorously tested and compatible with servers: Dell PowerEdge T150, T350, Lenovo ST250, HPE ML30 Gen10, Supermicro SYS-5019C-M.
Q: Can I mix this MTA9ASF51272AZ-2G1A1 with other memory modules of different brands or speeds?
A: Mixing this ECC UDIMM with modules of different brands, speeds, or rankings is not advised. Mismatched parameters can cause ECC errors, system instability, or failure to boot. For server reliability, install identical matched modules.
Q: Is this memory compatible with my system?
A: This DDR4-2133 ECC UDIMM is compatible with platforms using Intel Xeon E3-1200 v5/v6 or AMD Ryzen Pro processors that support unbuffered ECC memory. Verify your server board's qualified vendor list for exact support.
Q: What is the recommended DIMM population order for optimal performance?
A: For dual-channel platforms, populate identical modules in the primary slots of each channel, such as DIMM_A1 and DIMM_B1 first. Always follow your server motherboard's population guide to enable memory interleaving and maximize bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No, this is a JEDEC-compliant server memory module operating at fixed 2133MT/s, CL15, 1.2V. It does not support XMP or overclocking, as data integrity and stability are prioritized over speed in server environments.
Q: What warranty and typical failure rate can I expect?
A: This Micron module includes a 1-year warranty. Typical annualized failure rates for such enterprise-grade ECC UDIMMs are under 0.5%, reflecting high reliability when operated within specified environmental and workload conditions.
