HMCG78AEBRA107N - 16GB DDR5-4800 ECC RDIMM | SK hynix
MPN: HMCG78AEBRA107N ✓ Hoạt độngHMCG78AEBRA107N Tóm tắt
A Registered DIMM (RDIMM) is a memory module that buffers the address and command signals through a register chip before they reach the DRAM devices. This buffering reduces the electrical load on the memory controller, allowing servers and workstations to support more memory modules per channel than unbuffered UDIMMs. Within the memory hierarchy, RDIMM sits between standard desktop UDIMMs and load-reduced LRDIMMs, and with on-die ECC plus registered operation it is the standard choice for enterprise-class reliability.
Key features of the HMCG78AEBRA107N include the DDR5 architecture with 4800 MT/s data rate, ECC Registered operation for server-grade data integrity, 1.1V operating voltage for reduced power consumption versus DDR4's 1.2V, and the standard 288-pin DIMM connector. The x8 device width and single-rank configuration simplify population rules on dual-socket platforms. DDR5's split power delivery, moving the PMIC onto the module, improves signal integrity and power efficiency.
Technically, the module transfers data across a 64-bit data interface at 4800 MT/s, yielding PC5-38400 bandwidth of 38.4 GB/s per module. On-die ECC (ODECC) within the DDR5 DRAM devices corrects internal single-bit errors, while the registered architecture supports deeper memory populations. DDR5 doubles the number of independent banks versus DDR4, improving concurrency for virtualized workloads.
Typical applications include enterprise servers, blade systems, virtualization hosts, cloud computing nodes, and high-end workstations that specify DDR5-4800 RDIMM support.
Design and integration consideration: always verify that the target platform explicitly lists DDR5 RDIMM support - DDR5 modules are not backward compatible with DDR4 slots, and mixing RDIMM with UDIMM or LRDIMM is not supported on most platforms.

Ứng dụng tiêu biểu
HMCG78AEBRA107N phù hợp cho 6 Áp dụngs: Enterprise Server Main Memory, Virtualization and Cloud Hosts, High-Performance Workstations, Blade and Edge Compute Systems, Database and Analytics Servers, Memory Upgrade and Fleet Refresh.
Enterprise Server Main Memory
The HMCG78AEBRA107N is purpose-built for enterprise server main memory, where its 16GB DDR5-4800 configuration delivers 38.4 GB/s of bandwidth per module over a 64-bit interface. The ECC Registered architecture buffers address and command lines through a register, reducing electrical loading and allowing dense populations across multiple channels - typically 8 to 16 modules per dual-socket server. The 1.1V operating voltage lowers per-module power draw compared to DDR4's 1.2V, directly reducing data center cooling costs, while DDR5's on-die ECC corrects internal single-bit errors before they propagate. On a DDR5-4800 platform such as Intel Xeon Scalable or AMD EPYC servers, each populated module adds 16GB of registered, error-managed capacity.

Virtualization and Cloud Hosts
Virtualized workloads benefit directly from the HMCG78AEBRA107N's combination of capacity, bandwidth, and error management. Each virtual machine consumes a guaranteed memory slice, and the module's 4800 MT/s data rate with doubled bank count versus DDR4 improves concurrent access patterns typical of many-tenant hosts. On-die ECC plus registered operation protects against silent data corruption, which is critical when a single physical host runs dozens of customer workloads. A 2-socket server with 16 channels can accommodate multiple HMCG78AEBRA107N modules per channel, scaling from 256GB to over 1TB per node. The single-rank 1Rx8 design also allows mixing with dual-rank modules to balance capacity against channel rank limits.

High-Performance Workstations
Engineering workstations built around DDR5-4800 RDIMM-capable platforms use the HMCG78AEBRA107N for memory-intensive tasks such as finite element analysis, 3D rendering, and large dataset processing. The 38.4 GB/s per-module bandwidth feeds CPU-bound simulation workloads, while 16GB per module keeps population counts low - a workstation accepting eight modules reaches 128GB with just single-rank modules, minimizing memory controller stress. ECC protection matters in professional workflows: silent bit errors during a multi-hour simulation or render can invalidate results without visible symptoms. Because RDIMMs buffer command signals, they tolerate the heavier electrical environment of fully populated 8-DIMM workstation boards better than unbuffered desktop memory.

Blade and Edge Compute Systems
Blade servers and edge compute appliances prioritize power efficiency and thermal headroom, both strengths of the HMCG78AEBRA107N. Operating at 1.1V with DDR5's module-integrated PMIC, the module reduces the memory rail power draw roughly 9% versus equivalent DDR4 capacity, which is significant in enclosed blade chassis where airflow is constrained. The 288-pin standard DIMM form factor fits standard server DIMM sockets used across blade and short-depth edge platforms. DDR5's on-die ECC maintains data integrity in edge environments where unexpected shutdowns and elevated temperatures raise error rates. Edge deployments running containerized services benefit from the 16GB-per-module density, achieving 64-128GB in space-constrained nodes.

Database and Analytics Servers
In-memory database engines and analytics platforms such as SAP HANA-class workloads require maximum validated memory capacity with error correction, making the HMCG78AEBRA107N a fitting building block. Its 38.4 GB/s bandwidth per module sustains the sequential and random access intensity of column-store scans, while CL40 registered timing provides predictable latency under sustained load - important for consistent query response times. Servers populated entirely with single-rank modules like this one can sometimes achieve higher rated speeds than mixed-rank configurations, since fewer ranks per channel reduce command bus contention. For large in-memory footprints, admins commonly populate 16 modules of 16GB to reach 256GB per node with full ECC coverage.
Được đề xuất
Memory Upgrade and Fleet Refresh
The HMCG78AEBRA107N is a frequent selection for DDR5 server fleet upgrades because it matches the JEDEC DDR5-4800 baseline speed supported by first-generation DDR5 platforms (Intel Sapphire Rapids, AMD Genoa entry SKUs). Its HMCG78 family is widely referenced in OEM cross-reference lists, and Newegg certifies HMCG78MEBRA115N/174N as direct equivalents, simplifying mixed-supplier procurement. When upgrading an existing DDR5 fleet, purchasing the same base family keeps SPD profiles and population rules consistent, avoiding the down-clocking and rank-mixing pitfalls of heterogeneous memory. For buyers maintaining warranty support, sourcing the genuine SK hynix part through Microchip USA or Memory4Less preserves traceability for enterprise maintenance contracts.

Ghi chú thiết kế
Never install HMCG78AEBRA107N DDR5 RDIMMs in DDR4 or non-RDIMM platforms: despite sharing a 288-pin connector, DDR5 keying, voltage (1.1V vs 1.2V), and signaling are incompatible, and RDIMM buffering requires a registered-memory-capable memory controller. Mixing RDIMMs with UDIMMs or LRDIMMs in the same channel is not supported on mainstream server platforms. Before large-volume procurement, confirm the module suffix appears in the platform vendor's Qualified Vendor List (QVL), since suffixes encode die revisions that some platforms validate individually.
The HMCG78AEBRA107N operates at 1.1V with an onboard PMIC (DDR5 modules manage their own power rails). Estimated: a fully populated dual-socket server with 32 modules draws substantially less memory-rail power than an equivalent DDR4 1.2V configuration - roughly a 9% rail-voltage reduction before PMIC efficiency gains. Ensure the server chassis and power supply are rated for the total populated module count, and verify the BIOS/UEFI is updated to a revision supporting DDR5-4800 1Rx8 SPD profiles for correct training.
For best performance on DDR5-4800 platforms, populate channels symmetrically with identical modules - use the same MPN (or certified equivalent such as HMCG78MEBRA115N) across all channels. Memory controller training is most reliable with homogeneous populations; mixing single-rank (1Rx8) and dual-rank modules may force down-clocking below 4800 MT/s. Follow the server vendor's DIMM slot population order (usually white/black slots first) to maintain per-channel trace length matching specified in the platform's technical reference manual.
