This Micron 4GB DDR4-2400 registered memory module with ECC is purpose-built for entry-level server platforms, excelling in workloads that demand absolute data integrity such as lightweight virtualization, edge computing, and in-memory databases. The registered signal type stabilizes multi-DIMM channels, while its single-rank x8 organization and CL17 latency deliver responsive access and wide electrical compatibility across modern server chipsets.
1. ECC protection silently corrects single-bit errors in real time, preventing silent data corruption that could compromise financial transactions or long-running scientific computations.
2. Registered signal buffering reduces the electrical load on the memory controller, enabling the server to support vastly larger memory footprints for heavy virtualization and in-memory databases.
3. The RDIMM form factor ensures compatibility with server-class boards and provides the reliable, validated operation that data centers depend on for non-stop uptime.
4. DDR4 technology delivers higher bandwidth per watt, translating into reduced power bills and cooler-running racks while sustaining the throughput needed for multi-core CPU utilization.
5. The 2400MT/s transfer rate feeds data to the processor at a pace that keeps latency-sensitive workloads like caching layers and real-time analytics running smoothly under concurrent access.
Designed specifically for server deployments, the Micron MTA9ASF51272PZ-2G3B1QG RDIMM is engineered to eliminate the downtime and silent data corruption that keep IT managers awake at night. Its registered signal type buffers command and address lines, allowing your virtualization cluster or Hyper-V host to populate multiple DIMMs per channel without the signal integrity collapse that plagues unbuffered modules—meaning you can scale memory capacity confidently as VM density grows. Equally critical is ECC error correction: in an in-memory database like Redis or SAP HANA, a single undetected bit flip can cascade into transactional errors or kernel panics. The x8 single-rank organization here strikes a deliberate balance, delivering 2400 MHz bandwidth and CL17 latency with minimal bus loading, which directly translates to faster query responses and smoother live migration of virtual machines. At a 1.2V DDR4 low-power standard, this module reduces thermal load inside your 1U rack server, preserving component longevity. For any business where data integrity and continuous uptime are non-negotiable, this RDIMM converts four technical specifications into a single, tangible outcome: predictable performance under real enterprise pressure.
General Virtualization
For modest virtualization hosts running multiple light VMs, this 4 GB RDIMM is insufficient as a standalone module. Deploy at least four identical modules (16 GB total) in a balanced multi-channel configuration to provide adequate headroom for a hypervisor and guest operating systems. Scaling to eight modules across all memory channels improves memory bandwidth and reduces contention in multi-VM environments.
In-Memory Database
In-memory databases demand both capacity and reliability, and a single 4 GB DIMM is far below entry thresholds. Build a large registered ECC memory pool by populating all available channels with high-density modules, aiming for 64 GB or more to hold entire datasets in RAM. The error correction and registered signaling of this module class ensure data integrity during high-throughput transactional workloads.
High-Performance Computing
HPC clusters often require maximum memory bandwidth per node; a solitary 4 GB RDIMM cannot satisfy that requirement. Install one DIMM per memory channel—typically six or eight modules—to exploit the platform’s full interleaving capability. While 2400 MHz is a moderate speed, fully populating channels helps sustain near-peak bandwidth for memory-bound scientific simulations and modeling tasks.
This rigorously tested server memory is compatible with Dell PowerEdge R750, HPE ProLiant DL380 Gen10, and Lenovo ThinkSystem SR650.
Q: Can I mix this MTA9ASF51272PZ-2G3B1QG with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is not recommended. It can cause signal integrity issues and system instability. For mission-critical servers, always use identical modules validated for your platform.
Q: Is this memory compatible with my system?
A: This is a DDR4-2400 ECC Registered DIMM for server platforms. It requires a motherboard with a matching chipset that supports Registered ECC memory on Intel Xeon E5-2600 v4/Scalable or AMD EPYC 7001 series processors.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server motherboard’s population guide. Generally, populate the furthest white slots per channel first. Balanced loading across all memory channels ensures optimal performance and data integrity with this single-rank x8 RDIMM.
Q: Does this module support overclocking or XMP profiles?
A: No. As an enterprise ECC Registered server DIMM, it adheres strictly to JEDEC DDR4-2400 standards for maximum data integrity. Overclocking and XMP profiles are not supported on this module.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Enterprise RDIMMs like this Micron part are built with stringent testing and exhibit an extremely low annualized failure rate (AFR), typically well under 1%.
