This Micron DDR4-2933 Registered ECC RDIMM is engineered for enterprise servers and workstations, delivering hardened data integrity for virtualization, in-memory databases, and mission-critical workloads. Its single-rank x8 configuration and CL21 latency optimize signal stability and memory controller load, ensuring reliable throughput in dense, multi-DIMM deployments.
1. RDIMM architecture enables higher memory capacity per server node, keeping virtualization density high for consolidated workloads.
2. ECC protection eliminates single-bit memory errors, safeguarding data integrity in transactional databases and financial systems.
3. Registered buffer technology ensures clean command signals across multiple DIMMs, enabling stable operation in fully populated server boards.
4. DDR4 with elevated data rate supplies the memory bandwidth needed to feed multi-core processors during large-scale in-memory processing.
5. Low-voltage operation reduces energy draw and cooling demands, directly lowering total cost of ownership in hyperscale deployments.
The MTA9ASF1G72PZ-2G9J3R is engineered as an RDIMM for servers, where downtime or data corruption directly impacts revenue. Its ECC technology actively corrects single-bit errors caused by cosmic radiation or electrical noise — in a virtualized cluster running dozens of VMs, a silent bit flip in a financial database can cascade into transaction failures or costly system halts. ECC eliminates that risk at the hardware level, ensuring results you can audit and trust. The Registered signal buffer provides rock-solid signal integrity when populating all memory channels in a 2U rack node. For an in-memory database like Redis or SAP HANA, this means you can scale to higher total capacity without sacrificing stability, keeping microsecond-level query responses consistent under heavy load. DDR4-2933 speed pushes bandwidth to 23.4 GB/s, feeding modern multi-core Xeon processors efficiently so virtual machine migration and real-time analytics remain fluid. Single Rank x8 configuration minimizes electrical load on the memory bus, improving compatibility across mixed-density configurations and reducing latency-sensitive stutter when multiple database instances compete for I/O. For your data center, these four attributes together mean fewer service interruptions, predictable performance at scale, and longer platform reliability.
General Virtualization
For moderate consolidation of VMs, populate at least six to eight of these 8 GB RDIMMs per host to provide 48–64 GB of ECC memory. Distribute modules evenly across all memory channels (e.g., one DIMM per channel) to maximize bandwidth for simultaneous guest workloads while leaving expansion room for future density increases.
In-Memory Database
In-memory databases like Redis or SAP HANA demand both capacity and fault tolerance. Configure with a minimum of 16 identical modules (128 GB) installed in a balanced, fully-populated channel layout for the lowest latency. Opt for single-rank x8 DIMMs like these to sustain high operating frequencies, then scale to 256 GB or beyond as dataset sizes grow, always keeping memory ranks per channel equal.
High-Performance Computing
HPC applications thrive on memory bandwidth, so install one 8 GB RDIMM per channel across all available channels—typically eight modules on a dual-socket platform (64 GB total). This balanced, single-rank-per-channel configuration yields peak DDR4-2933 throughput for parallel MPI or simulation codes. Scale capacity by moving to 16 GB or 32 GB RDIMMs rather than adding more modules, preserving the one-DIMM-per-channel speed advantage.
Verified compatible: Dell PowerEdge R760, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650, and other ECC RDIMM servers. Rigorously tested.
Q: Can I mix this MTA9ASF1G72PZ-2G9J3R with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is not recommended. For reliable ECC and registered operation, use identical Micron modules with matching rank, CAS latency, and 2933 MT/s speed across all channels.
Q: Is this memory compatible with my system?
A: This DDR4-2933 registered ECC module targets Intel Xeon Scalable and AMD EPYC server platforms. Please verify compatibility against your server motherboard’s official memory QVL for 8GB single-rank RDIMMs.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical modules per channel, typically starting from the farthest slot from the CPU. Balanced configurations across memory channels maximize bandwidth and maintain ECC efficiency. Consult your server manual.
Q: Does this module support overclocking or XMP profiles?
A: No. This enterprise RDIMM operates at fixed JEDEC-standard timings (PC4-23400, CL21). It does not support overclocking or XMP profiles, ensuring 24/7 mission-critical stability.
Q: What warranty and typical failure rate can I expect?
A: It includes a 1-year warranty. As a Micron enterprise-grade RDIMM, it undergoes stringent qualification for an extremely low annualized failure rate, built for constant uptime in data centers.
