This 64GB DDR4-2933 registered ECC RDIMM module is engineered for server platforms, making it an ideal fit for memory-intensive workloads such as virtualization, in-memory databases, and enterprise applications that demand uncompromising data integrity. Its quad-rank x4 organization maximizes capacity density per channel while the registered signal type and ECC ensure robust signal stability and end-to-end error correction in multi-DIMM configurations.
1. A 64 GB capacity per module enables dense memory footprints that allow virtualization hosts to run more VMs per server without exhausting DIMM slots, directly boosting consolidation ratios.
2. ECC technology continuously corrects single-bit errors, preventing silent data corruption in financial transactions or database operations where accuracy is non-negotiable.
3. Registered signal buffering stabilizes the command and address buses, so fully populated multi-channel configurations maintain signal integrity under the heavy load of enterprise analytics.
4. Quad Rank x4 design doubles the DRAM count per module, delivering exceptional capacity density for in-memory computing platforms that cannot afford to waste physical slots.
5. 2933 MHz memory speed elevates sustained bandwidth, shrinking query times for large datasets and smoothing throughput spikes in virtualized or containerized environments.
The SK hynix HMAA8GR7MJR4N-WMT4AD is a 64GB DDR4-2933 registered server DIMM, engineered for enterprise workloads where stability and data integrity define business continuity. In a dense virtualization cluster running dozens of mission-critical VMs, the registered clock driver buffers command and address signals across heavily populated memory channels, eliminating the signal degradation that can cause random host crashes under load. This hardware-level buffering means your multi-tenant hypervisor environment stays up when every socket is maxed out. Simultaneously, integrated ECC silently corrects single-bit errors that would otherwise corrupt data in an in-memory database like SAP HANA or Redis—turning a potential financial discrepancy or flawed analytics query into a non-event. The quad-rank x4 organization not only enables massive 64GB capacity on a single module, but also improves bank interleaving, sustaining higher bandwidth during simultaneous database reads and virtual machine migrations without latency spikes. Running at a low 1.2V, the module further reduces power and cooling costs across a full rack, directly lowering your data center operating expenditure. For IT architects safeguarding virtualized infrastructures and real-time data platforms, these characteristics convert technical specifications into guaranteed uptime and unshakeable data trust.
Capacity Planning Guide for Server Memory (64GB DDR4-2933 ECC RDIMM)
This Hynix 64GB DDR4-2933 Registered ECC module is built for server-class workloads demanding data integrity and high capacity. Below are capacity planning recommendations for typical deployment scenarios.
General Virtualization
Virtualized environments thrive on balanced density and resilience. A dual-socket server with 16 such modules (1TB total) comfortably hosts dozens of mixed-workload VMs. Configure with memory mirroring or spare ranks if uptime is critical, sacrificing usable capacity for redundancy.
In-Memory Database
In-memory databases like Redis or SAP HANA require maximum speed and reliability. Populate all channels symmetrically with one module per channel (e.g., 8 modules for 512GB) to sustain high-frequency transactions. Avoid mixing different ranks or capacities to maintain predictable latency.
High-Performance Computing
HPC clusters demand immense bandwidth. Fully populate all memory channels per node (e.g., 16 modules for 1TB) to leverage interleaving and boost aggregate throughput. Match the configuration precisely across nodes to ensure consistent job performance and avoid memory-bound stragglers.
Rigorously tested, compatible with Dell PowerEdge R760, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650 servers.
Q: Can I mix this HMAA8GR7MJR4N-WMT4AD with other memory modules of different brands or speeds?
A: Mixing registered ECC modules of different brands or speeds is not recommended. Inconsistent ranks, timings, or SPID data can cause POST failures or silent data corruption in server environments. Use identical Hynix RDIMMs for guaranteed stability.
Q: Is this memory compatible with my system?
A: This DDR4-2933 registered ECC RDIMM is designed for server platforms such as Intel Xeon Scalable (Cascade Lake/Cooper Lake) or AMD EPYC 7002/7003 series. Verify your motherboard or system manual explicitly states support for 64GB quad-rank RDIMMs.
Q: What is the recommended DIMM population order for optimal performance?
A: Balance quad-rank DIMMs evenly across all memory channels following the server’s population guide. Typically, populate identical modules in the first slot of each channel (e.g., A1, B1, C1, D1) to enable multi-channel interleaving and maximize throughput.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-standard server RDIMM operating at 2933MHz with fixed CL21 timings. It does not support XMP or overclocking, as enterprise memory prioritizes data integrity and error correction over frequency flexibility.
Q: What warranty and typical failure rate can I expect?
A: This Hynix module includes a one-year warranty. Enterprise-class registered memory typically exhibits an annualized failure rate (AFR) below 0.5% under nominal thermal and workload conditions, ensuring long-term mission-critical reliability.
