Engineer's Note

This RDIMM is engineered for server-class platforms, ideally suited for virtualization, in-memory databases, and mission-critical workloads where data integrity is paramount. Its ECC and registered signal architecture ensure robust error correction and stable operation under heavy load, while the dual-rank x8 configuration and CL17 latency optimize memory bandwidth for sustained high-throughput processing.

Technical Specs & Insights

1. Error correction code detects and corrects single-bit memory errors in real time, safeguarding transactional databases and financial computations from silent data corruption.
2. Registered signal buffering stabilizes high-density memory configurations, enabling large-scale virtualization hosts to run reliably under extreme DIMM population.
3. Dual-rank x8 organization interleaves memory banks to sustain peak channel utilization, reducing latency jitter for latency-sensitive enterprise applications.
4. Sixteen-gigabyte capacity per module provides a granular building block for cost-optimized server deployments, balancing memory footprint and investment in multi-node clusters.
5. DDR4-2400 base frequency delivers consistent memory bandwidth, ensuring stable throughput for moderate-intensity workloads such as web farms and container platforms.

Why These Specs Matter

In mission-critical data centers, the HMA82GR7MFR8N-UH 16GB DDR4-2400 RDIMM delivers four engineering cornerstones that directly defend uptime and performance. Its ECC technology actively corrects single-bit memory errors, a silent threat in virtualized clusters where a flipped bit can corrupt the hypervisor and every VM running on it, preserving data integrity for in-memory databases like SAP HANA. The registered clock buffer cleanses and re-drives signal paths, allowing you to fill all 24 DIMM slots without signal degradation; this means dense VMware or Hyper-V farms reliably consolidate hundreds of workloads without sudden system hangs. Built as a dual-rank x8 module, it unlocks rank interleaving that accelerates concurrent accesses, so transactional databases or Redis instances see lower queuing delays and more predictable sub-millisecond response under heavy user loads. Finally, the 1.2V operating voltage squeezes thermal demands in fully populated racks, shrinking cooling costs across large-scale deployments. For virtualization and database professionals, these four traits translate directly into hardened stability, faster query throughput, and lower total cost of ownership.

Endurance & Reliability

Capacity Planning Guide for Server Memory (DDR4-2400 ECC RDIMM)

General Virtualization
For a typical hypervisor host, balance core count with memory channels. One 16 GB RDIMM per populated channel ensures 1 DPC (DIMM per Channel) for peak signal integrity. Start with modules per CPU to match total cores, scaling to 6 or 12 modules for dual-socket systems to support 100+ VMs.

In-Memory Database
Latency matters, and registered ECC memory with CL17 delivers stability for Redis or SAP HANA. Populate all memory channels symmetrically with at least one module per channel to maximize bandwidth. A mid-range node can use 8 modules (128 GB total) for in-memory datasets up to 100 GB, leaving headroom for OS and replication buffers.

High Performance Computing
HPC workloads demand the highest sustainable bandwidth. Install one 16 GB dual-rank module in every populated channel to leverage rank interleaving. For dual-socket servers with 8 channels each, 16 identical modules (256 GB) achieve near-peak STREAM bandwidth, while keeping DPC to one prevents frequency drops on daisy-chain topologies.
