This unbuffered ECC DDR4-2666 UDIMM is ideally suited for entry-level servers and workstations where data integrity is critical, such as file servers, NAS appliances, or light virtualization hosts. Its dual-rank x8 organization boosts memory bandwidth through interleaving while the integrated ECC engine corrects single-bit errors in real time, ensuring 24/7 operational stability without the cost premium of registered memory.
1. Integrated ECC corrects single-bit errors in real time, preserving data accuracy for continuous financial transactions and preventing silent corruption in long-running database instances.
2. Dual Rank x8 organization enables rank interleaving that keeps memory channels saturated, sustaining stable throughput when consolidating multiple virtual machines on entry-level servers.
3. 1.2V operation reduces power draw per module, lowering cooling demands and energy costs across dense server racks that run around the clock.
4. DDR4-2666 throughput delivers ample bandwidth for in-memory caching and real-time analytics, ensuring responsive data access under concurrent user loads.
5. Unbuffered signal architecture trims access latency compared to registered alternatives, offering a responsive advantage for latency-sensitive workloads while retaining full ECC protection.
The Micron MTA18ASF1G72AZ-2G6B1 is an 8GB DDR4-2666 ECC UDIMM engineered for entry-level servers and professional workstations where data integrity cannot be compromised. Its ECC engine silently corrects single-bit errors, safeguarding virtualized workloads and financial databases from silent corruption that could trigger transaction rollbacks or unexpected system crashes. The unbuffered architecture eliminates register latency, delivering the low-latency responsiveness that single-socket platforms like Intel Xeon E and AMD Ryzen PRO require to efficiently run multiple virtual machines and real-time analytics. A dual-rank layout interleaves accesses across two internal x8 ranks, boosting sustainable bandwidth for memory-intensive operations such as in-memory caching for a fleet management database or live log processing. Operating at just 1.2V, the module significantly reduces power draw and thermal stress compared to older memory generations, which is critical for always-on NAS appliances storing encrypted backups or edge servers performing continuous surveillance recording. In these deployments, every design choice directly fortifies uptime and data accuracy, translating into uncompromising reliability for your business-critical processes.
General Virtualization
For a moderate virtualization host, install four of these 8GB ECC UDIMMs to reach 32GB. This balanced quad-channel configuration supports several light VMs and containers while maintaining error correction for data integrity. Scale to six or eight modules (48–64GB) if you need extra headroom for denser workloads.
In-Memory Database
Latency-sensitive in-memory databases benefit from the dual-rank x8 design, which improves rank interleaving and response times under load. Deploying eight modules (64GB) populates all channels and delivers the capacity needed for Redis or Memcached instances without sacrificing reliability.
High-Performance Computing
For memory-bandwidth-bound HPC jobs, fully populate the platform’s eight DIMM slots with 64GB total. The ECC and 1.2V efficiency help sustain long-running simulations, while the DDR4-2666 speed and dual-rank layout provide steady throughput per channel.
Rigorously tested server memory compatible with Dell PowerEdge R240, HPE ProLiant DL20 Gen10, Lenovo ThinkSystem ST250.
Q: Can I mix this MTA18ASF1G72AZ-2G6B1 with other memory modules of different brands or speeds?
A: Mixing ECC UDIMMs with different brands or speeds is not recommended. It may cause signal integrity issues, force all modules to the lowest common speed, and disable error correction reliability on server platforms.
Q: Is this memory compatible with my system? Which Intel or AMD platforms are supported?
A: This ECC Unbuffered DDR4 module is compatible with Intel Xeon E3/E-2100/2200 series and AMD Ryzen PRO or EPYC 3000 platforms using C242/C246 chipsets. Verify 288-pin ECC UDIMM support on your motherboard’s qualified vendor list.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical ECC UDIMMs in matched sets, starting with the slots farthest from the CPU per your server board manual. For dual-socket systems, balance memory equally across both memory channels to maintain symmetric multiprocessing efficiency.
Q: Does this module support overclocking or XMP profiles?
A: No. As a JEDEC-compliant server ECC UDIMM, it runs at fixed 2666MHz with CL19. Overclocking and XMP are not supported, as operational stability and data integrity are prioritized over performance tuning in server environments.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year limited warranty. Typical annualized failure rates for Micron ECC UDIMMs are below 0.5% under specified operating conditions. Extended warranties may be available through authorized partners.
