Designed for server platforms, this 16GB DDR4-2666 RDIMM with ECC and registered signal technology ensures data integrity and system stability for demanding workloads like virtualization and in-memory databases. Its dual-rank x8 configuration improves memory bandwidth utilization, while the low 1.2V operating voltage and CL19 latency deliver an optimal balance of power efficiency and responsiveness in multi-DIMM server deployments.
1. Error-correcting code capability detects and corrects single-bit memory faults automatically, protecting transactional databases from silent data corruption in always-on enterprise environments.
2. Registered signal buffering stabilizes command and address lines even under fully loaded configurations, allowing dense server memory populations without compromising system integrity.
3. Dual rank organization interleaves memory accesses across internal banks, sustaining peak channel utilization and low-latency data delivery for heavily consolidated virtual machines.
4. This speed grade supplies ample throughput for concurrent analytics and virtualization workloads, ensuring responsive multi-tenancy on modern cloud platforms.
5. The module’s capacity footprint boosts VM density per physical node, giving data center operators headroom to scale containerized services without immediate hardware expansion.
The Micron MTA18ASF2G72PDZ-2G6H1R is a 16GB DDR4-2666 RDIMM purpose-built for servers, where uptime and data integrity are non-negotiable. Its ECC capability automatically corrects single-bit memory errors caused by cosmic radiation, shielding virtualized clusters from silent corruption that could crash hypervisors during live migration. Registered logic buffers the command bus, preserving signal clarity when all four channels are fully populated—this ensures rock-solid stability in dense virtualization hosts or memory-hungry database nodes. The dual-rank x8 design interleaves memory accesses, increasing effective bandwidth for applications like Redis caching layers that must serve tens of thousands of concurrent queries per second. Operating at 2666MT/s with a low 1.2V, it delivers high throughput while reducing power draw per DIMM, lowering cooling costs in 42U racks. For in-memory analytics and large-scale virtualization, this blend of error resilience, scalability, and power efficiency means fewer downtimes and faster transactions—protecting both your data and your budget.
Capacity Planning for DDR4-2666 ECC RDIMM (16GB)
This registered, ECC memory module is built strictly for servers. Plan populations to balance channels and respect rank limits for reliable, high-throughput operation.
General Virtualization
Populate all memory channels identically—one 16 GB RDIMM per channel per socket provides optimal bandwidth. In a dual‑socket server with six channels each, twelve modules deliver 192 GB, comfortably hosting dozens of mixed‑workload VMs. If density matters more, move to two DIMMs per channel while maintaining symmetry.
In‑Memory Database
Low latency and consistent access are critical. Use two dual‑rank x8 DIMMs per channel (2DPC) to maximise capacity without exceeding typical rank limits, reaching 384 GB per socket. Configure all channels equally to avoid NUMA imbalances; the registered buffer stabilises signal integrity under heavy loads, making 16 GB RDIMMs ideal for large in‑memory datasets.
High Performance Computing
Bandwidth‑sensitive HPC fares best with one DIMM per channel (1DPC)—six modules per CPU yield 96 GB and run at full 2666 MT/s. For capacity‑bound simulations, move to 2DPC while accepting a minor speed reduction. Always mirror the population across both sockets to sustain symmetrical, high‑bandwidth memory access.
Rigorously tested, compatible with Dell PowerEdge R760, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650.
Q: Can I mix this MTA18ASF2G72PDZ-2G6H1R with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is not recommended. In a server, it degrades reliability and forces all modules to operate at the lowest common speed, potentially causing stability issues.
Q: Is this memory compatible with my Intel or AMD server platform?
A: This 16GB DDR4-2666 ECC RDIMM is compatible with Intel Xeon Scalable and AMD EPYC platforms that support 288-pin registered memory. Verify that your motherboard explicitly supports ECC RDIMMs.
Q: What is the recommended DIMM population order for optimal performance with this module?
A: Populate identical modules per channel starting with the slot farthest from the CPU (usually slot 1). Balance total capacity across all memory channels according to your server manual to maximize bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No, this is a server-grade ECC Registered DIMM. It operates strictly at JEDEC standard DDR4-2666 for mission-critical reliability and does not support overclocking or XMP profiles.
Q: What warranty and typical failure rate can I expect?
A: It includes a 1-year warranty. Enterprise ECC RDIMMs exhibit an extremely low annualized failure rate, typically under 0.5%, due to stringent testing and high-quality components.
