This 32GB DDR4-2933 Registered ECC module is purpose-built for enterprise server environments requiring high data integrity and stability, such as virtualization hosts and in-memory databases. Its Dual Rank x4 organization combined with ECC and a registered signal type ensures robust error correction and reliable operation under heavy, sustained workloads with minimal signal degradation.
1. ECC protection silently corrects single-bit errors, safeguarding transactional data integrity for mission-critical enterprise workloads.
2. Registered signal buffering stabilizes high-density memory configurations, enabling seamless scalability across a fully populated virtualization host.
3. Generous module capacity maximizes virtual machine density, allowing more concurrent workloads per server without sacrificing responsiveness.
4. High-speed throughput accelerates in-memory databases and real-time analytics, reducing query latency under peak concurrent user loads.
5. Dual Rank x4 architecture interleaves memory accesses across rank boundaries, sustaining channel saturation for consistent multi-tenant application performance.
When you are scaling a virtualization cluster or powering an in-memory database like SAP HANA, the HMA84GR7JJR4N-WMT4AA RDIMM does not just fit a slot—it directly protects your uptime and transaction throughput. This 32GB DDR4-2933 module brings four engineered characteristics that matter deeply in the data center. Its ECC actively corrects single-bit memory errors caused by background radiation, so a flipped bit will not silently corrupt a financial record or hypervisor state, preventing unexplained VM crashes that wake your team at 3 a.m. The Registered signal buffer isolates the electrical load from the memory controller, letting you populate all channels with multiple DIMMs without sacrificing signal integrity; that means you can confidently scale a server to terabyte-class capacity for dense virtual desktop infrastructure without random boot failures. The dual-rank x4 organization enables rank interleaving, so while one rank is refreshing, the other responds—vital for the microsecond-level latency demands of Redis or Memcached instances under heavy load. Finally, operating at 1.2V instead of legacy voltage levels lowers cumulative power draw across a rack of nodes, reducing cooling strain and operating costs as your memory footprint grows. For your mission-critical workloads, this memory transforms specifications into tangible resilience, scalability, and energy efficiency.
Capacity Planning for This Hynix 32GB DDR4‑2933 Registered ECC RDIMM
This module is a server‑grade RDIMM. Optimal capacity planning depends entirely on workload profile.
General Virtualization
Populate all memory channels uniformly to maximise bandwidth. Install one 32 GB DIMM per channel (often 8 modules per socket for 256 GB) to maintain 2933 MT/s and balanced NUMA access. If denser VM packing is required, move to two DIMMs per channel using identical dual‑rank modules, but expect the speed to drop to 2666 MT/s due to heavier electrical loading on the bus.
In‑Memory Database
Maximise total capacity while preserving data integrity. Fill every slot with these 32 GB RDIMMs – a 24‑slot server yields 768 GB – and always use the same dual‑rank parts to keep the configuration consistent. Never mix different capacities or rank types, as this can introduce ECC‑correctable errors and latency jitter that hurt transactional throughput.
High‑Performance Computing
Prioritise memory bandwidth over sheer capacity. A one‑DIMM‑per‑channel (1DPC) layout with these dual‑rank 32 GB modules keeps the memory clock at the full 2933 MHz and delivers the lowest access latency. Pair 8 identical sticks per socket for 256 GB of balanced, high‑throughput memory, which is ideal for parallel simulation, CFD and molecular dynamics workloads where every cycle counts.
Stringently tested for server compatibility. Verified with Dell PowerEdge R740, R640, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650.
Q: Can I mix this HMA84GR7JJR4N-WMT4AA with other memory modules of different brands or speeds?
A: Mixing is strongly discouraged. For a registered ECC DDR4-2933 RDIMM, mixing brands or speeds may cause memory errors and system instability. Always install identical modules to maintain signal integrity and reliable ECC operation.
Q: Is this memory compatible with my system?
A: This RDIMM is designed for server platforms supporting DDR4-2933 ECC registered memory, such as Intel Xeon Scalable (2nd Gen or newer) or AMD EPYC 7002/7003 series. Verify your server board's qualified vendor list for compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your motherboard manual’s sequence, typically filling the furthest slot per channel first. Populate balanced channels evenly to maximize memory bandwidth and ensure proper ECC mirroring or lockstep capabilities.
Q: Does this module support overclocking or XMP profiles?
A: No. As an enterprise-grade registered ECC memory, this Hynix RDIMM runs at a fixed JEDEC-standard 2933 MHz. It does not support overclocking, XMP, or end-user speed tuning.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. With Hynix’s stringent enterprise testing, its annualized failure rate is typically under 0.5%, ensuring dependable operation for mission-critical server workloads.
