This RDIMM is engineered for server platforms prioritizing data integrity and reliable operation in virtualized environments and memory-intensive databases, leveraging ECC and registered signal technology to maintain stability under sustained heavy loads. Its single-rank x8 configuration with CL21 latency ensures efficient memory controller loading, delivering consistent 2933MHz performance ideal for enterprise workloads like in-memory analytics.
1. Registered signal type ensures the memory controller drives a clean, buffered command/address bus, which is essential for maintaining signal integrity across densely populated server motherboards with numerous DIMM slots.
2. ECC protection automatically corrects single-bit errors and detects multi-bit corruption, safeguarding transactional data and preventing silent data decay in long-running enterprise applications.
3. The 2933 MT/s transfer rate delivers substantial memory bandwidth per channel, accelerating in-memory databases and reducing latency for concurrent virtual machines under heavy consolidation.
4. An 8 GB capacity per module strikes an efficient balance, allowing IT architects to populate servers with enough memory for lightweight virtualization hosts or dedicated caching nodes without overspending on idle resources.
5. Single Rank x8 organization reduces electrical loading on the memory bus, enabling stable operation at rated speed in fully loaded server systems and lowering the risk of timing-related failures.
The Micron MTA9ASF1G72PZ-2G9E1 is an 8 GB DDR4-2933 registered DIMM engineered for server environments, and four of its characteristics directly determine the reliability and performance of mission-critical infrastructure. Error Correcting Code (ECC) is essential when you run virtualized clusters or in-memory databases like SAP HANA: it detects and corrects single-bit flips caused by background radiation, preventing silent data corruption that could crash a hypervisor hosting dozens of virtual machines. The registered signal type incorporates an onboard clock buffer that stabilizes the command and address lines, so you can populate all 24 slots on a dual-socket board without signal degradation—this keeps large-scale virtualization deployments stable even under heavy memory capacity stress. At 2933 MHz, the module delivers a peak bandwidth of 23.4 GB/s, which translates directly into faster live migration of VMs and snappier query responses on Redis or Memcached instances where every microsecond of latency counts. Finally, the single-rank x8 organization limits electrical loading on the memory channel, reducing access latency and allowing the server’s memory controller to sustain higher command rates during concurrent analytical workloads. Together, these traits mean fewer outages, predictable low latency, and the assured data integrity that your database transactions and virtualized services demand around the clock.
General Virtualization
For general virtualization, populate memory channels symmetrically with 8 GB RDIMMs—e.g., 4 × 8 GB (32 GB) or 8 × 8 GB (64 GB)—to enable interleaving and ensure ECC reliability. Single‑rank x8 modules reduce electrical load, sustaining 2933 MT/s speeds under moderate VM density.
In‑Memory Database
Databases like Redis or SAP HANA demand maximum capacity. Fill all DIMM slots with these 8 GB registered ECC DIMMs to reach the server’s limit, such as 16 × 8 GB for 128 GB. Balance modules across channels for optimal cache‑line interleaving, preserving low latency for real‑time queries.
High Performance Computing (HPC)
HPC workloads require high sustained bandwidth. Install identical 8 GB DDR4‑2933 RDIMMs in every memory channel—typically six or eight DIMMs—to harness full memory interleaving. The registered single‑rank x8 design minimizes loading, and the consistent CL21 latency supports predictable performance. Follow recommended population order to avoid NUMA imbalances.

Q: Can I mix this MTA9ASF1G72PZ-2G9E1 with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is strongly discouraged in server environments. It often leads to POST failures or stability issues. Always use identical modules to ensure data integrity and validated performance.
Q: Is this memory compatible with my system?
A: This DDR4-2933 ECC Registered DIMM is designed for server platforms supporting RDIMMs, such as Intel Xeon Scalable and AMD EPYC. Please verify your motherboard's Qualified Vendor List to confirm compatibility with specific configurations.
Q: What is the recommended DIMM population order for optimal performance?
A: Refer to your server motherboard's population guidelines. Typically, populate the first slot of each memory channel (often the white or blue ones) to enable balanced interleaving. Symmetrical installation across CPU memory controllers maximizes bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No, this is a JEDEC-compliant server memory module and does not support XMP profiling or overclocking. It operates rigidly at 2933MHz with CL21 timings to guarantee 24/7 data integrity under enterprise workloads.
Q: What warranty and typical failure rate can I expect?
A: It carries a one-year warranty. As enterprise-grade Micron RDIMM, the typical annualized failure rate is extremely low (AFR <0.5%), backed by rigorous production screening and burn-in testing for maximum reliability.
