Ideal for virtualization and in-memory database workloads, this 16GB DDR4-2933 RDIMM with ECC ensures data integrity in mission-critical server environments. Its registered signal type and single-rank x8 configuration provide superior signal stability and memory bus efficiency, enabling reliable scaling in dense multi-DIMM deployments.
1. The error correction capability detects and corrects single-bit flips automatically, preserving data integrity in transactional databases and financial workloads where silent corruption is unacceptable.
2. Registered signal buffering stabilizes high-capacity memory configurations, allowing dense server racks to scale reliably without signal degradation across multiple DIMMs.
3. Sufficient capacity per module ensures each virtual machine guest gets dedicated memory headroom, reducing hypervisor swapping and sustaining predictable performance under consolidation pressure.
4. High data rate aligns with modern server processor pipelines, accelerating in-memory analytics and real-time query responses by minimizing access bottlenecks.
5. Single Rank construction reduces electrical loading on the memory channel, enabling consistent clock stability and sustained bandwidth in multi-slot server deployments.
Based on the RDIMM form factor, ECC support, and registered signal type, the Micron MTA9ASF2G72PZ-2G9E1R is a server-class memory module purpose-built for mission-critical enterprise workloads. Its four defining characteristics translate directly into tangible reliability and performance gains for your data center. The onboard ECC engine autonomously corrects single-bit errors, preventing silent data corruption that could crash an entire virtualization cluster or introduce inaccuracies in a high-frequency trading in-memory database, preserving transactional integrity when it matters most. The registered signal buffer decouples the memory controller from the electrical demands of the DRAM chips, enabling you to fully populate a server with large capacities while maintaining rock-solid signal stability, a non-negotiable prerequisite for hosting dozens of virtual machines on a single physical host. Its single-rank x8 architecture minimizes channel contention and command bus loading, reducing access latencies that directly boost the random read performance critical for real-time analytics platforms like Apache Spark or a massive Redis cache. Together with the DDR4-2933 speed and frugal 1.2V operating voltage, this module delivers high throughput while lowering thermal stress and energy costs in dense rack deployments, ensuring your VMs and databases receive a constant, clean stream of data without throttling. This design expressly alleviates the pain points of downtime, uncaught data errors, and I/O bottlenecks that plague scaled-out server infrastructure.
General Virtualization
For a typical hypervisor hosting multiple VMs, populate all memory channels with identical 16GB RDIMMs to balance capacity and bandwidth. A 6- or 8-channel configuration using six to eight modules delivers 96GB–128GB, comfortably supporting dozens of moderate workloads while maintaining NUMA locality.
In-Memory Database
In-memory databases demand both large capacity and low latency. Deploying 12 or 16 of these ECC Registered modules per server provides 192GB–256GB, allowing entire datasets to reside in RAM and preventing swap. The 2933MT/s speed with CL21 offers a solid latency floor for real-time query processing.
High-Performance Computing
HPC workloads thrive on memory bandwidth, so fill every channel on a dual-socket platform with one DIMM per channel (1DPC). Using 16 modules achieves 256GB of ECC-protected capacity and peak throughput, critical for tightly coupled parallel simulations. Prioritize populating all channels symmetrically to avoid bandwidth drops.
Rigorously tested server memory, compatible with Dell PowerEdge R740, R750, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650, and more.
Q: Can I mix this MTA9ASF2G72PZ-2G9E1R with other memory modules of different brands or speeds?
A: Mixing is strongly discouraged. Registered ECC modules must match in rank, organization, and speed to maintain signal integrity. Mismatched DIMMs may cause POST failures or memory errors on server platforms.
Q: Is this memory compatible with my Intel Xeon Scalable or AMD EPYC server?
A: Compatibility requires a DDR4-2933 ECC RDIMM supported platform. Verify with the server board's qualified vendor list. This module works with Intel Xeon Scalable (2nd Gen and later) and AMD EPYC 7002/7003 series using 288-pin slots.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per memory channel, starting with the furthest white slot from the CPU. Follow the server manual's balanced or multi-channel configuration to maximize interleaving and avoid performance penalties.
Q: Does this module support overclocking or XMP profiles?
A: No. As a JEDEC-compliant server RDIMM, it operates at fixed 2933MHz with CL21 timings. XMP and manual overclocking are not supported to ensure 24/7 data integrity and stability in enterprise environments.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. It is built with rigorous testing for enterprise workloads, yielding an annualized failure rate (AFR) well below 0.5% under specified conditions, ensuring reliable long-term operation.
