This 16GB DDR4-2400 ECC Unbuffered UDIMM is engineered for entry-level servers and workstations demanding data integrity, ideally suited for virtualization environments and in-memory database applications. The dual-rank x8 organization boosts memory interleaving for higher effective bandwidth, while hardware ECC corrects single-bit errors in real time to safeguard critical workloads against silent data corruption.
1. ECC protection detects and corrects single-bit errors in real time, safeguarding transactional data integrity for always-on microserver workloads.
2. Dual Rank x8 organization increases bank-level parallelism, delivering higher sustained bandwidth under concurrent virtual machine and container densities.
3. Sixteen-gigabyte capacity per module supplies ample headroom for memory-hungry hypervisor hosts without immediately filling all DIMM slots.
4. DDR4 technology doubles the internal bank groups over its predecessor, improving command efficiency during mixed read/write traffic in virtualized environments.
5. Operating at a native 2400 megatransfers per second, this memory provides balanced throughput that aligns well with entry-level server-class processors, keeping latency predictable under load.
The Micron MTA18ADF2G72AZ-2G3B1ZK is a 16GB DDR4-2400 ECC Unbuffered UDIMM engineered specifically for entry-level servers and high-stakes workstations where data integrity cannot be compromised. Its four defining characteristics translate directly into real-world reliability. The ECC circuitry is your first line of defence against single-bit errors caused by background radiation—silent corruption that could crash a hypervisor during a ten-hour virtualization batch or mangle financial records in an in-memory database. Because this is an unbuffered module, you skip the additional clock-cycle latency of registered alternatives, giving PostgreSQL or Redis faster command-to-response paths when microsecond delays hurt transaction throughput. The dual-rank x8 organization keeps the memory controller interleaving across two ranks, furnishing the extra bandwidth that multiple virtual machines demand when they fight for I/O resources simultaneously. Finally, the strict 1.2V operating voltage curbs power draw in compact microserver chassis, reducing thermal stress and leaving more energy budget for CPU boosting. For a VMware vSAN node or a small SAP HANA instance, these attributes together mean uninterrupted uptime, sharper query performance under concurrency, and a cooler, leaner platform that scales securely with your workload.
General Virtualization
For a hypervisor host running multiple VMs, populate all available memory channels with identical 16GB ECC UDIMMs to ensure balanced performance and data integrity. A typical dual-socket or single-socket server with 4 or 6 channels can reach 64–96GB using four to six modules, which comfortably supports 10–15 moderate VMs. Always deploy modules in matched sets to maintain ECC protection and avoid mixing speeds or ranks.
In-Memory Database
In-memory databases like Redis or SAP HANA demand low latency and absolute data reliability, making this 16GB ECC UDIMM a solid building block. Equip the server with the maximum supported number of identical DIMMs—often 4 or 8 for single-socket platforms—to achieve 64–128GB, allowing the entire dataset to reside in RAM. Dual-rank x8 construction helps sustain throughput, but fill all channels to avoid bandwidth bottlenecks under heavy in-memory workloads.
High-Performance Computing (HPC)
For compute-node memory in HPC clusters, install six or eight of these 16GB modules across all memory channels to maximize bandwidth (e.g., 96–128GB per node). The ECC feature is critical for long-running simulations where silent data corruption cannot be tolerated. Given the 2400MHz speed and CL17 latency, this configuration suits capacity-optimized HPC tasks; for latency-bound codes, consider paired modules in every channel to leverage dual-rank interleaving gains.
Rigorously tested, compatible with servers such as Dell PowerEdge R240, R340, T140, HPE ProLiant MicroServer Gen10 Plus, and more.
Q: Can I mix this MTA18ADF2G72AZ-2G3B1ZK with other memory modules of different brands or speeds?
A: Mixing is not recommended for server memory. ECC UDIMMs demand identical ranks, timings, and voltage to maintain data integrity. Mismatched modules may cause parity errors or system instability.
Q: Is this memory compatible with my server? Which Intel or AMD platforms are supported?
A: It fits servers with DDR4 ECC UDIMM support, such as Intel Xeon E3-1200 v5/v6 on C232/C236 chipsets, or select AMD Ryzen PRO platforms. Verify your motherboard supports unbuffered ECC memory.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server board’s manual. Typically, populate identical DIMMs in the same-colored slots first to enable dual-channel mode. Use balanced configurations across memory channels to maximize throughput.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a server-grade ECC UDIMM running at JEDEC-standard DDR4-2400. It does not support XMP or overclocking, as stability and error correction take priority over frequency tuning.
Q: What warranty and typical failure rate can I expect?
A: It comes with a 1-year warranty. The module is built to stringent server-grade standards, yielding a very low annualized failure rate under normal operating conditions, comparable to industry expectations for ECC memory.
