This 8GB DDR4-2666 ECC unbuffered DIMM is engineered for workstations and entry-level servers where data integrity is critical, making it ideal for virtualization, light in-memory databases, and content verification workloads. Its single-rank x8 configuration and CL19 latency deliver reliable signal integrity and low electrical loading, while on-die ECC actively corrects single-bit errors to prevent silent data corruption.
1. DDR4 technology elevates throughput per watt over previous generations, allowing a single-socket server to handle more concurrent connections without breaching thermal limits.
2. ECC actively corrects single-bit errors in real time, safeguarding transactional databases and file systems against silent data corruption during continuous operation.
3. 2666 MT/s transfer rate keeps memory bandwidth comfortably ahead of multi-core CPU demands, reducing latency spikes for virtual desktops and containerized microservices.
4. Single-rank x8 organization lowers bus loading, which helps maintain clean signal integrity and ensures reliable boot-up compatibility across a variety of workstation and entry-server motherboards.
5. Operating at the standard 1.2 V, the module cuts waste heat and aggregate rack power consumption, lowering the total cost of ownership for always-on edge and small-business deployments.
Judging by its specifications, the MTA9ASF1G72AZ-2G6 is an unbuffered ECC DDR4 UDIMM built for workstations and entry-level servers—systems where cost-conscious reliability and responsiveness cross paths. In virtualized environments running multiple lightweight VMs, a single-bit memory error can cascade into silent data corruption, crashing workloads or compromising financial logs. The on-die ECC engine corrects these flips in real time, effectively turning random faults into non-events so your hypervisor stays stable without costly downtime.
For in-memory databases like Redis or MySQL with heavy read caches, low latency directly shapes transaction throughput. As an unbuffered module, it eliminates the extra clock cycle that registered memory imposes, keeping CAS latency to a tight CL19. Combine that with 2666MHz bandwidth and single-rank x8 organization, and query responses remain snappy even under simultaneous connections. The native 1.2V operation also means less waste heat in compact server chassis—lowering cooling overhead in always-on deployments while preserving the power budget for additional drives or networking cards. This isn’t just about filling a DIMM slot; it’s about ensuring every bit you trust stays correct and every microsecond counts when your application can’t afford to wait.
This is an 8GB DDR4-2666 ECC Unbuffered UDIMM, purpose-built for entry-level servers and data-critical workstations. Rely on ECC to guard against single-bit errors in 24/7 environments. The capacity planning guidelines below address its ideal deployment across three common server workloads.
General Virtualization
For a hypervisor hosting 8–12 light VMs, install four identical 8GB modules (32GB total) to enable quad-channel interleaving. This balanced configuration provides sufficient memory headroom for typical virtualized services while ECC eliminates stability risks from background radiation-induced errors. Add two more modules to scale to 48GB if running additional guests or memory-overcommitment.
In-Memory Database
Small Redis or Memcached instances thrive on consistent latency and data integrity. Populate every available DIMM slot with these 8GB ECC sticks—an eight-slot platform delivers 64GB of error-protected capacity. Even distribution across all memory channels maximizes throughput, making it suitable for caching hot datasets that cannot tolerate silent corruption.
High-Performance Computing (HPC)
Memory-bound scientific simulations demand peak bandwidth and absolute correctness. Deploy six or eight identical modules (48–64GB) to fully saturate the processor’s memory channels, ensuring optimal interleaving. In long-running computational fluid dynamics or weather modeling jobs, ECC is non-negotiable to prevent bit-flip propagation that would invalidate results.
Rigorously tested server memory, proven compatible with Dell PowerEdge T140, T340, HPE ProLiant ML30 Gen10, and more.
Q: Can I mix this MTA9ASF1G72AZ-2G6 with other memory modules of different brands or speeds?
A: Mixing ECC UDIMMs from different brands or speeds is not recommended. It may cause system instability, unbuffered ECC errors, or force all modules to run at the lowest common speed, compromising server reliability.
Q: Is this memory compatible with my system? (Which Intel or AMD platforms are supported?)
A: This DDR4-2666 ECC UDIMM works with platforms like Intel Xeon E-2100/E-2200 series and AMD AM4 Ryzen PRO or select EPYC 3000 embedded CPUs. Verify your motherboard supports unbuffered ECC memory.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical ECC UDIMMs per channel, starting with the furthest slot from the CPU for each channel. Always consult your server motherboard manual for the specific balanced memory configuration layout.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant server-grade ECC UDIMM. It runs at standard 2666MHz with no XMP or overclocking support, prioritizing data integrity and 24/7 operational stability over speed.
Q: What warranty and typical failure rate can I expect?
A: This Micron module includes a 1-year warranty. Built with enterprise-class components, it delivers an extremely low annualized failure rate (AFR) typically under 0.4%, ensuring high reliability for critical workloads.
