This DDR3L 1600 MT/s ECC Unbuffered DIMM is tailored for entry-level servers and workstations where data integrity is critical, with error-correcting code and a low 1.35V operating voltage ensuring stable 24/7 operation and energy efficiency. Its dual-rank x8 organization boosts memory bandwidth through rank interleaving, making it ideal for light virtualization, file serving, and financial computing workloads that demand reliable throughput at moderate capacities.
1. ECC protection silently corrects single-bit memory errors, safeguarding transactional databases and preventing data corruption during continuous server operation.
2. 16 GB capacity per module enables dense virtualization footprints, allowing more virtual machines to reside on a single physical host without sacrificing guest responsiveness.
3. 1600 MHz speed delivers consistent memory bandwidth for concurrent workloads, ensuring stable throughput for mid-tier enterprise applications under peak load.
4. Dual Rank x8 organization optimizes interleaving across memory banks, boosting command scheduling efficiency and reducing latency in heavily threaded server tasks.
5. 1.35V low-voltage operation reduces power draw and cooling demands within rack environments, translating to lower energy costs and improved thermal headroom for colocation deployments.
The Micron MT18KDF2G72AZ-1G6A1 is a 16GB DDR3-1600 ECC Unbuffered DIMM built for entry-level servers and workstations where data integrity and energy efficiency are vital. Its ECC corrects single-bit errors from background radiation in real time, preventing silent data corruption. In a virtualized cluster, this guarantees hypervisor stability and stops a random bit flip from crashing your VMs. For in-memory databases like Redis, ECC safeguards transactional records from undetectable errors, essential for financial or healthcare accuracy. The module runs at just 1.35V, dramatically cutting thermal load and power costs in always-on deployments—a critical factor in dense server farms. Its dual-rank x8 design uses rank interleaving to amplify bandwidth and reduce latency during heavy concurrent workloads. As a 240-pin UDIMM, it delivers cost-effective ECC protection without registered buffer costs, giving SMB servers the data resilience, low-power efficiency, and steady throughput demanded by real-world virtualization and database applications.
General Virtualization
For a hypervisor hosting multiple VMs, populate all memory channels evenly to maximize bandwidth. Using four of these 16GB ECC UDIMMs in a quad-channel server provides 64GB, a balanced starting point for light to moderate workloads. Scale to eight modules (128GB) if your platform supports dual-socket or dense VM packing, always respecting identical DIMMs per channel to maintain memory interleaving.
In-Memory Database
In-memory databases like Redis or SAP HANA demand both capacity and data integrity. Deploy the largest supported set of these 16GB ECC modules to reach 128GB or 256GB, fully populating all DIMM slots with identical part numbers. The unregistered ECC design keeps latency slightly lower than registered alternatives, which benefits transaction-heavy workloads, while ECC scrubs protect against silent data corruption.
High-Performance Computing (HPC)
Memory bandwidth is critical for HPC simulation and modeling. Install one DIMM per channel to achieve the highest DDR3-1600 speed without loading-induced downclocking. In a typical dual-socket server with four channels per CPU, eight of these modules deliver 128GB and full channel interleaving, minimizing bottlenecks during large-mesh data transfers. Avoid mixing ranks or speeds within the same channel to preserve predictable low-latency access patterns essential for tightly coupled parallel jobs.
Strictly tested, compatible with Dell PowerEdge T20, Lenovo ThinkServer TS140, and other ECC UDIMM servers.
Q: Can I mix this MT18KDF2G72AZ-1G6A1 with other memory modules of different brands or speeds?
A: Mixing is not recommended for servers. It may cause instability. For mission‑critical environments, always populate with identical part numbers to ensure signal integrity and reliability.
Q: Is this memory compatible with my system? (Intel/AMD server platforms)
A: It fits platforms supporting DDR3 ECC UDIMMs, such as Intel Xeon E3-1200 v2/v3 or AMD AM3+ single‑socket servers. Verify the motherboard QVL for 16GB dual‑rank x8 modules.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical modules in the first slot of each memory channel (usually blue slots) to enable dual‑channel interleaving. Refer to your server board manual for specific slot numbering.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC‑compliant DDR3-1600 CL11 server module. It does not support XMP or overclocking, prioritizing error‑free 24/7 operation over performance tuning.
Q: What warranty and typical failure rate can I expect?
A: It includes a one‑year warranty. Enterprise DDR3 ECC UDIMMs have very low annualized failure rates under specified conditions, designed for sustained always‑on workloads.
