Engineer's Note

Designed for enterprise-grade servers, this 16GB DDR4-2133 Registered DIMM with ECC ensures data integrity and system stability under demanding workloads such as virtualization and in-memory databases. Its dual-rank x4 organization and registered signal type reduce bus loading and improve signal reliability, making it ideal for scaling memory capacity in multi-slot server platforms.

Technical Specs & Insights

1. 16GB capacity per module allows dense memory configurations that support larger virtual machine footprints and faster in-memory database processing without filling every DIMM slot prematurely.
2. ECC error correction automatically detects and corrects single-bit data corruption, directly protecting transactional integrity in financial and healthcare server environments.
3. Registered signal buffering stabilizes electrical loads across fully populated memory channels, preserving uptime when scaling to multi-terabyte enterprise server farms.
4. Dual Rank x4 organization interleaves memory bank accesses, delivering higher sustained bandwidth under concurrent query loads typical of virtualized data centers.
5. 1.2V low operating voltage curbs power draw and waste heat generation, directly lowering cooling overhead in dense rack-server deployments.

Why These Specs Matter

Judging by its RDIMM form factor, ECC support, and registered signal type, the MTA36ASF2G72LZ-2G1A1HK is engineered exclusively for servers and workstations where downtime is unacceptable. In a virtualized cluster hosting dozens of business‑critical VMs, ECC error correction serves as your silent guardian. It actively detects and corrects single‑bit memory errors caused by background radiation, preventing silent data corruption from cascading into database index damage or financial record discrepancies. The registered buffer then stabilizes the command interface, allowing you to populate all 24 DIMM slots on a dual‑socket motherboard without signal degradation, so you achieve the massive capacity your hypervisors demand with unwavering reliability.

For an in‑memory database like Redis or SAP HANA, the dual‑rank x4 organization becomes a performance multiplier. It enables bank interleaving that reduces latency by overlapping operations across internal banks, accelerating complex in‑memory analytics queries while shrinking application response times. Finally, the 1.2V DDR4 low‑voltage design directly translates to a cooler and more cost‑effective data center. Across a fleet of servers, this lower power consumption cuts both electricity bills and cooling requirements, extending platform longevity so your investment remains productive around the clock.

Endurance & Reliability

General Virtualization
For general virtualization hosts, populate all memory channels symmetrically to maximize bandwidth. Using this 16GB DDR4-2133 RDIMM, install at least four identical modules (64GB total) to handle moderate VM densities without creating memory bottlenecks. Scale to eight modules (128GB) when hosting memory-intensive workloads or more VMs per socket.

In-Memory Database
In-memory databases demand large capacity and fault tolerance, making ECC registered memory essential. Deploy six or eight of these 16GB RDIMMs per CPU (96–128GB) to keep entire datasets in RAM for sub-millisecond latency. The dual-rank x4 design improves signal integrity under heavy load, so populate channels evenly to sustain consistent performance during peak query throughput.

High-Performance Computing (HPC)
HPC applications rely on memory bandwidth as much as capacity. Fully populate each memory channel with identical 16GB RDIMMs — typically 8 or 12 modules in a dual-socket node — to exploit the platform’s peak interleaving. The 1.2V operating voltage helps control thermals in dense compute clusters, and the CL15 latency provides a predictable balance between speed and stability for tightly-coupled parallel jobs.
