This 64 GB DDR5-4800 Registered DIMM with ECC and dual-rank x4 organization is engineered for enterprise servers running memory-intensive workloads such as virtualization and in-memory databases, where its registered signaling ensures signal integrity across dense memory channels and ECC protects against data corruption. The dual-rank configuration maximizes bank-level parallelism to sustain high throughput at the module’s rated 4800 MT/s while maintaining the energy efficiency benefits of the 1.1 V DDR5 standard.
1. 64 GB capacity allows dense memory configurations, enabling a single server to run significantly more virtual machines or containers without resorting to slower storage.
2. DDR5-4800/PC5-38400 standard delivers a substantial bandwidth uplift per core, accelerating real-time analytics and large in-memory database operations under sustained load.
3. ECC error correction proactively detects and repairs bit-flips, protecting critical financial or scientific computations from silent data corruption around the clock.
4. Registered signal buffering stabilizes command and address lines across fully populated channels, ensuring reliable operation when scaling to multi-terabyte memory footprints in enterprise racks.
5. Dual Rank x4 organization leverages rank interleaving to hide row-access latency, keeping throughput high even when multiple virtualized workloads compete for the same memory controller.
The HMCG94MEBRA126N is a 64GB DDR5-4800 Registered DIMM with ECC, purpose-built for enterprise servers where data integrity and massive scalability directly affect revenue and uptime. Its ECC technology instantly corrects single-bit errors, preventing silent data corruption that could crash entire virtual machines or introduce financial discrepancies in transactional databases. The Registered buffer amplifies command signals, enabling a server to pack every channel with high-density modules without signal collapse—vital when a virtualization cluster must deliver terabytes of reliable memory to hundreds of VMs. With 64GB on a single stick, you maximize capacity per slot, letting you fit complete datasets in RAM for in-memory platforms like SAP HANA or Redis; this eliminates storage bottlenecks and accelerates real-time analytics. Complementing this density, the DDR5-4800 speed and dual-rank x4 architecture supply 38.4 GB/s of bandwidth, sustaining high throughput during simultaneous database queries and heavier VM shuffle operations. That combination means your infrastructure confidently hosts more users and larger workloads without compromising stability or response times.
General Virtualization
For dense server virtualization, this 64 GB DDR5-4800 Registered ECC DIMM is an ideal building block. A dual‑socket platform with eight memory channels per CPU can accommodate one module per channel (1DPC) to maximize bandwidth, delivering 512 GB per socket while maintaining 4800 MT/s speed. This configuration supports a high number of virtual machines with headroom for memory overcommitment, and ECC ensures data integrity across the entire virtualized environment.
In-Memory Database
In‑memory databases like SAP HANA or Redis demand maximum capacity and absolute reliability. Populate all available channels with this 64 GB RDIMM to scale total memory into the terabyte range—for example, 16 modules in a dual‑CPU server yield 1 TB. The Registered ECC design prevents single‑bit errors from corrupting critical transactional data, and the dual‑rank x4 construction delivers the low latency necessary for real‑time query processing.
High-Performance Computing
HPC workloads require both high bandwidth and strong error protection. Using one 64 GB module per memory channel (1DPC) preserves 4800 MHz operation and maximizes memory throughput per node, which is crucial for simulation and modeling codes. For capacity‑intensive HPC tasks like computational fluid dynamics, populating two modules per channel is acceptable if total memory scale outweighs the slight speed reduction; ECC remains mandatory to ensure calculation accuracy over long‑running jobs.
Validated for servers. Tested with Dell PowerEdge R760, HPE ProLiant DL380 Gen11, and Lenovo ThinkSystem SR650 V3.
Q: Can I mix this HMCG94MEBRA126N with other memory modules of different brands or speeds?
A: Mixing modules in a registered server environment is not recommended. It risks signal integrity and ECC stability, potentially causing system instability or data errors. Always use identical, validated SKUs for mission-critical deployments.
Q: Is this memory compatible with my system?
A: This DDR5-4800 registered ECC DIMM is designed for server platforms supporting DDR5 RDIMM, such as Intel Xeon Scalable (Sapphire Rapids) or AMD EPYC 9004 Series. Confirm your motherboard qualified vendor list includes 64GB dual-rank x4 DIMMs.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow the server board memory population guide carefully. Typically, populate one DIMM per channel first in the primary slots for balanced interleaving, then add second DIMMs symmetrically to maximize throughput across all memory channels.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant registered ECC module engineered for 24/7 data-center reliability at 4800 MT/s. It does not support XMP or manual overclocking, prioritizing error-free operation and long-term stability over peak frequency.
Q: What warranty and typical failure rate can I expect?
A: This Hynix module includes a one-year warranty. Enterprise-grade manufacturing and rigorous binning result in an extremely low annualized failure rate, typically below 0.5% in well-cooled, properly managed server environments.
