Engineer's Note

This 16GB DDR4-2400 ECC RDIMM is purpose‑built for server platforms running memory‑intensive workloads such as virtualization and in‑memory databases. The Registered signal type combined with Dual Rank x4 organization and a CAS latency of 17 delivers stable signal integrity and efficient bank interleaving, while ECC ensures data integrity under continuous operation.

Technical Specs & Insights

1. RDIMM design aligns with enterprise server architectures, ensuring seamless integration and stable operation under 24/7 mission-critical workloads.
2. ECC protection automatically detects and corrects single-bit memory errors, preserving transactional data integrity in financial databases and virtualized environments.
3. Registered signal buffering reduces electrical load on the memory controller, enabling high-density memory populations that sustain reliability when scaling up virtualization hosts.
4. Dual Rank x4 organization keeps memory channels fully saturated through interleaving, delivering consistent low-latency bandwidth for heavy VM consolidation.
5. DDR4-2400/PC4-19200 throughput provides balanced per-channel bandwidth, efficiently handling concurrent read/write operations in data-intensive analytics platforms.

Why These Specs Matter

The MTA36ASF2G72PZ-2G3B1RK is a 16GB DDR4-2400 RDIMM engineered for server workloads. Its four critical features—ECC, Registered buffer, Dual Rank x4, and 1.2V operation—directly tackle the demands of virtualized clusters and in-memory databases. ECC promptly corrects single-bit soft errors, shielding your hypervisor from silent VM corruption and unplanned downtime. The Registered buffer minimizes electrical loading on the memory controller, enabling you to fully populate all DIMM slots with uncompromised signal integrity, which is essential when scaling a virtualization host to support hundreds of VMs. The Dual Rank x4 design interleaves memory banks to amplify effective bandwidth, dramatically accelerating transaction throughput and real-time analytics in databases like Redis and SAP HANA under heavy load. Finally, the 1.2V supply reduces power draw against legacy modules, cutting cooling costs and improving thermal margin in dense racks. Altogether, these characteristics deliver the predictable performance and data reliability your mission-critical applications depend on.

Endurance & Reliability

General Virtualization
With 16GB RDIMMs, a balanced virtualization host can accommodate moderate VM densities. Deploy six to eight identical modules per dual‑socket server to populate one DIMM per memory channel, achieving 96‑128 GB total. This configuration supplies sufficient capacity for mixed workloads while preserving memory bandwidth through uniform channel distribution.

In‑Memory Database
In‑memory databases like Redis or SAP HANA demand high capacity and reliability, making registered ECC essential. Start with eight 16GB modules (128 GB) for small production instances, ensuring dual‑rank x4 organization maximizes bank‑group parallelism. Scale to sixteen modules (256 GB) on two‑socket platforms to hold larger datasets entirely in RAM, minimizing storage I/O latency.

High‑Performance Computing
HPC clusters benefit from consistent memory performance and data integrity. Equip each node with six or eight 16GB RDIMMs (96‑128 GB), matching the CPU memory channels to sustain 2400 MT/s throughput. The low 1.2V operating voltage helps reduce node‑level power draw, allowing denser rack deployments while ECC guards against silent data corruption during long simulation runs.
