This 64GB DDR4-2933 registered ECC module (RDIMM) is purpose-built for enterprise servers and is ideally suited for memory-intensive workloads such as virtualization, in-memory databases, and large-scale data analytics. Its quad-rank x4 configuration maximizes capacity density per channel, while the registered signal architecture and integrated ECC deliver superior electrical stability and end-to-end data integrity in multi-DIMM deployments.
1. Its high-density capacity allows a single server node to host significantly more virtual machines, boosting consolidation ratios without sacrificing per-VM memory headroom.
2. The elevated memory bandwidth accelerates in-memory databases and real-time analytics, reducing latency for data-intensive enterprise workloads.
3. Integrated ECC silently corrects single-bit errors, preserving long-haul data integrity essential for financial transactions and mission-critical services.
4. Registered signal buffering stabilizes command and address lines when populating multiple DIMMs per channel, enabling massive total memory footprints without compromising reliability.
5. Quad-rank x4 organization packs maximum capacity per module while maintaining balanced channel loading, ideal for virtualization hosts that demand both density and sustained throughput.
When deploying mission-critical virtualization clusters or in-memory databases, the HMAA8GR7MJR4N-WMT4AA RDIMM directly addresses the risks that keep IT architects awake at night. Its ECC technology continuously detects and corrects single-bit memory errors caused by cosmic radiation or electrical noise, preventing silent data corruption that could crash a multi-tenant hypervisor or poison a financial transaction in Redis. The registered signal buffer stabilizes the heavy electrical load of a 64 GB Quad Rank x4 module, allowing you to fully populate server nodes without sacrificing signal integrity—a necessity when scaling a VMware farm or a large SAP HANA instance. With 2933 MHz bandwidth and quad rank interleaving, this DIMM overlaps read/write operations across internal banks, delivering predictably low latency for virtual machine density and real-time analytics. The 1.2 V operating voltage further reduces thermal stress in dense rack environments, sustaining consistent performance across 24/7 operation. This memory does not just meet the spec sheet—it ensures your critical workloads survive the invisible threats that commodity memory ignores.
General Virtualization
Install these 64GB RDIMMs in balanced pairs across dual- or multi-channel architectures. Two modules (128GB) comfortably handle a moderate virtual machine density; for larger farms, populate one DIMM per memory channel on an 8-channel server to reach 512GB while sustaining the full 2933 MHz speed. ECC and registered buffering maintain stability as you scale.
In-Memory Database
Maximize throughput by filling every channel with a single 64GB quad-rank DIMM, delivering up to 512GB at full 2933 MHz bandwidth on an 8-channel platform. If raw capacity outweighs peak frequency, install two DIMMs per channel, accepting that quad-rank loading typically forces a speed reduction to 2666 MHz or lower.
High-Performance Computing
Equip each socket with four identical 64GB DIMMs (256GB) distributed evenly across memory channels. This symmetric layout sustains 2933 MHz operation, lowers NUMA latency, and provides the bandwidth critical for simulation and large-scale modeling. Rely on the module’s ECC protection to guard long-running compute jobs against silent data corruption.

Q: Can I mix this HMAA8GR7MJR4N-WMT4AA with other memory modules of different brands or speeds?
A: Mixing registered server DIMMs is not advised. Different ranks, speeds, or vendors may cause signal integrity issues. Use identical 64GB 2933MHz quad-rank Hynix RDIMMs across channels to ensure reliability and stable performance.
Q: Is this memory compatible with my system?
A: This 64GB DDR4-2933 RDIMM is built for servers with Intel Xeon Scalable or AMD EPYC platforms. Confirm your motherboard supports 2933MHz, registered ECC, quad-rank x4 modules and 288-pin DIMM slots before purchasing.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server’s population guide; usually fill identical DIMMs into matching color slots across all memory channels first. For quad-rank modules, balance capacity per channel to maximize throughput and prevent performance penalties.
Q: Does this module support overclocking or XMP profiles?
A: No. As an enterprise registered ECC module, it runs strictly at JEDEC-defined 2933MHz with CL21. Overclocking or XMP is not supported and would compromise the error correction required for mission-critical server workloads.
Q: What warranty and typical failure rate can I expect?
A: This Hynix module includes a 1-year warranty. Enterprise-class DDR4 RDIMMs like this have an annualized failure rate typically below 0.2% under proper cooling, ensuring excellent long-term operational reliability.
