This DDR4-3200 Registered ECC RDIMM is server-class memory purpose-built for virtualized environments, in-memory databases, and enterprise workloads that demand uncompromising data integrity. Its dual-rank x8 organization enhances memory interleaving efficiency on multi-channel platforms, while the registered signal type and ECC deliver improved signal stability and single-bit error correction in dense, high-capacity configurations.
1. Registered DIMM architecture maintains clean command and address signals under heavy memory loading, ensuring consistent uptime in large-scale enterprise servers.
2. On-the-fly ECC correction eliminates single-bit errors before they propagate, safeguarding financial transactions and scientific computations against silent data corruption.
3. Dual Rank organization enables rank interleaving that saturates memory channels more effectively, boosting transactional throughput under high concurrency.
4. The module’s capacity supplies sufficient headroom to multiply virtual machine density, letting a single host absorb more tenants without immediate hardware expansion.
5. High data-rate operation accelerates in-memory caching and analytics workloads, cutting latency on real-time dashboards that businesses rely on.
The HMA82GR7DJR8N-XN is a 16GB DDR4-3200 RDIMM engineered for server reliability. Its four defining features—ECC, Registered buffer, Dual Rank, and 3200MT/s at 1.2V—solve real-world data center challenges. ECC corrects single-bit errors before they silently corrupt financial transactions or bring down a virtual machine in a multi-tenant cloud cluster. Without it, a cosmic-ray-induced bit flip could cost you hours of troubleshooting or lost data. Registered buffering stabilizes signal integrity when every DIMM slot is filled, allowing a virtualization host to scale memory seamlessly to accommodate dozens of VMs. Dual Rank x8 interleaves memory accesses, boosting bandwidth for in-memory databases such as Redis or SAP HANA; queries return faster, driving real-time analytics. Finally, 3200 MT/s low-voltage operation balances high throughput with power efficiency, cutting thermal load in dense racks. This module transforms raw capacity into dependable, high-speed enterprise memory.
Based on the ECC Registered specification, this capacity planning guide applies to server deployments using 16 GB DDR4-3200 RDIMMs.
General Virtualization
Populate all memory channels with identical 16 GB RDIMMs — for an 8-channel platform, eight modules yield 128 GB of balanced capacity. This symmetric configuration delivers uniform memory access and leaves room for scaling VM density. The dual-rank design boosts bandwidth without sacrificing stability under moderate consolidation.
In-Memory Database
Maximize capacity by filling every channel and slot with these 16 GB dual-rank RDIMMs, easily reaching 512 GB or more. Symmetrical population preserves the performance edge needed for low-latency data sets. ECC and registered signaling safeguard transactional integrity during sustained, heavy analytical workloads.
High-Performance Computing (HPC)
Adopt a one DIMM per channel (1DPC) strategy to sustain the full 3200 MT/s speed, avoiding frequency drops. Eight modules supply 128 GB, a sweet spot for parallel simulations and modeling. Dual-rank x8 architecture provides higher sustained bandwidth, which directly benefits memory-bound HPC codes.
Strictly tested server memory, compatible with Dell PowerEdge R750, HPE ProLiant DL380 Gen10, and Lenovo ThinkSystem SR650 V2.
Q: Can I mix this HMA82GR7DJR8N-XN with other memory modules of different brands or speeds?
A: Mixing RDIMMs with different brands or speeds is not advised. It can cause signal integrity issues, POST failures, or unstable server operation. For mission-critical stability, use identical Hynix DDR4-3200 registered ECC modules.
Q: Is this memory compatible with my server? Which platforms are supported?
A: This Hynix DDR4-3200 RDIMM is compatible with servers using Intel Xeon Scalable (Purley/Whitley) or AMD EPYC platforms that support 288-pin registered ECC memory. Always consult your system's qualified vendor list.
Q: What is the recommended DIMM population order for optimal performance?
A: For optimal performance, populate identical DIMMs per channel starting from the slot farthest from the CPU. Follow your server manual's memory population rules, typically filling blue slots first to maintain balanced memory interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-standard DDR4-3200 CL22 registered ECC module operating at 1.2V. It does not support overclocking, XMP profiles, or timing adjustments beyond the standard specification.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Hynix enterprise RDIMMs demonstrate extremely low annualized failure rates, typically below 0.2%, ensuring dependable operation for your server workloads.
