This is a server-class DDR4-2666 Registered ECC DIMM, ideally suited for virtualization hosts, in-memory databases, and mission-critical workloads where data integrity is paramount. Its registered signal topology ensures stable operation in densely populated multi-DIMM configurations, while the dual-rank x8 organization and CL19 latency deliver consistent throughput under sustained memory access.
1. ECC protection silently corrects single-bit memory errors, preserving data integrity for transactional databases and financial workloads.
2. Registered buffering stabilizes command and address signals across high-density server boards, ensuring reliability even with all DIMM slots populated.
3. Dual-rank organization enables interleaving across DRAM banks, sustaining high bandwidth for dense virtualization and container environments.
4. The 2666MT/s transfer rate delivers consistent throughput ideal for concurrent virtual machine traffic and real-time analytics.
5. Sixteen-gigabyte module capacity lets infrastructure architects pack more memory into two-socket servers, maximizing guest density without sacrificing channel balance.
The Micron MTA18ASF2G72PDZ-2G6D1SI RDIMM directly addresses critical server pain points through four key attributes. ECC memory actively detects and corrects single-bit errors caused by cosmic radiation or electrical noise, preventing silent data corruption that could destabilize virtualized clusters or miscalculate transactions in financial databases. Registered buffering isolates the memory controller from heavy bus loads, so you can fully populate dual-socket boards with high-capacity DIMMs while maintaining signal integrity—vital for dense virtualization hosts running dozens of VMs. Dual-rank x8 bank interleaving boosts effective bandwidth for in-memory databases like SAP HANA, where microsecond latency directly impacts revenue. DDR4-2666 speed at 1.2V supplies 21.3 GB/s per module, cutting power and cooling expenses across server farms. For a hypervisor cluster, this ensures stable VM densities; for a real-time analytics engine, it delivers error-free, low-latency queries.
The 16GB DDR4-2666 ECC Registered RDIMM (PC4-21300, dual-rank, CL19) is a server-grade memory module. Below is capacity planning guidance for common server workloads.
General Virtualization
For hypervisor hosts running mixed VMs, install one DIMM per channel to balance bandwidth and capacity. A dual‑socket server populated with 6 or 12 modules (96GB or 192GB) satisfies most consolidation needs while preserving full 2666MT/s speed. Leave slots open for future scale‑out.
In‑Memory Database
Platforms like SAP HANA or Redis require massive, reliable memory. Fully populate memory channels with these dual‑rank RDIMMs to maximize bank interleaving and ECC protection. A symmetric 24‑module layout (384GB per server) across both processors delivers the necessary capacity and avoids NUMA penalties.
High‑Performance Computing (HPC)
HPC jobs demand sustained memory bandwidth and consistent latency. Configure one DIMM per channel using identical modules, avoiding multiple DIMMs per channel that would downclock the speed. In a dual‑socket node, 12 modules (192GB) equip all cores with uniform memory access, and matched sets preserve signal integrity under full load.
Rigorously tested for server compatibility. Compatible with Dell PowerEdge R740, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650, and more.
Q: Can I mix this MTA18ASF2G72PDZ-2G6D1SI with other memory modules of different brands or speeds?
A: Mixing RDIMMs with different brands, speeds, or ranks is strongly discouraged. Inconsistent electrical characteristics can undermine registered signal integrity and cause system instability or POST failures. Uniformity is essential for enterprise reliability.
Q: Is this memory compatible with my Intel Xeon or AMD EPYC server platform?
A: This 16GB DDR4-2666 ECC RDIMM is compatible with systems using Intel Xeon Scalable or AMD EPYC 7000/7002 series processors that support 288-pin registered DIMMs. Verify your motherboard’s memory QVL for exact population rules.
Q: What is the recommended DIMM population order for optimal performance on a server board?
A: Populate identical DIMMs per channel, usually starting with the furthest slot from the CPU. Follow the board’s labeling (A1, B1, etc.) to balance interleaving. All channels should mirror each other for maximum memory bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. This JEDEC-standard ECC registered DIMM does not support overclocking or XMP. It operates solely at the platform-determined 2666MHz to guarantee data integrity and mission-critical stability in server environments.
Q: What warranty and typical failure rate can I expect for this server memory?
A: This Micron module includes a one-year warranty. Designed for 24/7 enterprise workloads, it delivers an exceptionally low annualized failure rate (AFR), typically well below 0.5%, ensuring long-term data center dependability.
