Designed for server platforms, this DDR4-2666 RDIMM with ECC and registered signaling ensures data integrity in memory-intensive workloads such as virtualization and in-memory databases. The dual-rank x8 configuration boosts interleaving efficiency while the CL19 latency and 1.2V operation deliver a balance of reliable throughput and energy-conscious deployment.
1. ECC error correction actively detects and fixes single-bit memory errors, preventing silent data corruption in financial transactions and critical database operations.
2. Registered signal type buffers command and address signals, enabling stable population of large-capacity memory arrays essential for virtualized server farms.
3. 16 GB capacity per module strikes an optimal balance for dense server deployments, allowing substantial total memory without overwhelming per-channel load limits.
4. 2666 MHz speed fuels consistent memory bandwidth, matching mainstream server CPU capabilities to keep containerized microservices responsive under load.
5. Dual rank x8 organization interleaves memory accesses across two internal ranks, boosting effective bandwidth and reducing latency in heavy multi-tenant virtualization environments.
Built for the relentless demands of enterprise servers and data centers, the Micron MTA18ASF2G72PDZ-2G6E1QI is a 16GB DDR4-2666 RDIMM that turns four critical engineering features into tangible operational advantages. Its ECC circuitry silently corrects single-bit memory errors caused by cosmic radiation, a non-negotiable defense when a flipped bit in a financial database or a patient record could cascade into silent data corruption. The registered signal buffer acts as an electrical amplifier on the command bus, allowing a virtualization host to populate all 24 DIMM slots without signal degradation, so you can confidently scale VM density across a cluster without mysterious crashes at high capacity. Dual-rank x8 organization interleaves pages across two internal ranks, feeding the memory controller with data from one rank while the other precharges, which directly accelerates in-memory databases like SAP HANA or Redis where microsecond latency reductions compound into thousands of faster transactions per second. Finally, the 1.2V operating voltage reduces thermal load in dense rack environments, keeping cooling costs in check while maintaining rock-solid 2666MT/s throughput. In a hypervisor cluster, this module keeps live-migrated VMs intact; in a high-frequency trading cache, it ensures every query lands on reliable, low-latency cells. That is the difference between infrastructure you trust and infrastructure you merely hope will hold.
General Virtualization
Populate all memory channels symmetrically with these 16 GB registered ECC RDIMMs. A balanced 6-DIMM (96 GB) or 8-DIMM (128 GB) configuration per CPU socket delivers ample capacity and bandwidth for hosting dozens of virtual machines. Scale by adding identical matched pairs to preserve memory interleaving and NUMA locality as workload density grows.
In-Memory Database
Fill every available DIMM slot with identical 16 GB modules; a dual-socket server easily accommodates 512 GB or more to keep entire datasets resident. ECC and registered signaling guarantee end-to-end data integrity, while symmetric channel population eliminates latency spikes. This homogeneous footprint reliably supports OLTP and real-time analytics with consistent low-latency access.
High-Performance Computing
Install one module per memory channel (typically eight or six channels per CPU) to achieve 128 GB or 96 GB of balanced bandwidth. The dual-rank x8 design at 2666 MHz supplies the steady throughput required for simulation and modeling codes. Populate all sockets identically to ensure uniform memory access across NUMA domains, which is crucial for MPI job scaling and predictable cluster performance.
Rigorously tested server memory. Compatible with Dell PowerEdge R740, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650.
Q: Can I mix this MTA18ASF2G72PDZ-2G6E1QI with other memory modules of different brands or speeds?
A: Mixing with different brands or speeds is not recommended. Registered ECC memory requires uniform configurations to maintain signal integrity and system stability; mismatched modules may cause errors or system failure.
Q: Is this memory compatible with my system?
A: This DDR4-2666 RDIMM is designed for Intel Xeon Scalable and AMD EPYC server platforms. Please verify your motherboard or server vendor's QVL to ensure support for 16GB Dual Rank x8 ECC Registered DIMMs.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server board's manual: typically, populate identical DIMMs in symmetric slots per memory channel (e.g., A1, B1, C1, D1) to enable all memory channels and achieve balanced interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-grade Registered ECC DIMM, it adheres strictly to JEDEC DDR4-2666 standards. Overclocking and XMP are not supported, ensuring maximum data integrity and 24/7 operational reliability.
Q: What warranty and typical failure rate can I expect?
A: This module carries a one-year warranty. Its enterprise-class build and rigorous testing result in an extremely low annualized failure rate (AFR), typically below 0.5% under specified conditions, ensuring long-term reliability.
