Hynix HMCG84MEBRA115N 32GB DDR5 Server Memory Module
Next-Generation Server Memory Technology
The Hynix HMCG84MEBRA115N represents the cutting edge of server memory technology, delivering unprecedented performance, reliability, and efficiency for modern data center environments. This 32GB DDR5 module marks a significant evolution from previous DDR4 technology, offering substantial improvements in speed, power consumption, and data integrity. Engineered specifically for enterprise servers, cloud computing infrastructure, and high-performance computing applications, this memory module addresses the growing demands of data-intensive workloads in today's digital economy.
DDR5 Architectural Advancements
DDR5 technology introduces fundamental architectural changes that differentiate it from previous generations. The Hynix HMCG84MEBRA115N leverages these innovations to provide superior performance characteristics. Unlike DDR4, DDR5 features a dual 32/40-bit subchannel architecture that improves memory access efficiency and reduces latency. The implementation of Decision Feedback Equalization (DFE) enables higher data rates while maintaining signal integrity, crucial for server environments where data accuracy is paramount.
Power Management Innovations
One of the most significant advancements in DDR5 technology is the relocation of power management from the motherboard to the memory module itself. The Hynix HMCG84MEBRA115N incorporates an integrated voltage regulator, allowing for more precise power delivery and improved power efficiency. This on-DIMM power management system reduces motherboard complexity while providing better voltage regulation, resulting in enhanced stability and reliability under varying load conditions.
Detailed Key Specifications
Memory Configuration and Performance
The Hynix HMCG84MEBRA115N is configured as a 32GB capacity module operating at 4800MHz, providing substantial bandwidth for memory-intensive applications. With a PC5-38400 designation, this module delivers a peak transfer rate of 38.4GB/s, significantly outperforming DDR4 modules of comparable capacity. The 1Rx4 (single rank, x4 organization) configuration optimizes memory access patterns and reduces electrical load on the memory controller, enabling better signal integrity and higher operating frequencies.
Electrical Characteristics and Timing
Operating at a nominal voltage of 1.1V, the HMCG84MEBRA115N achieves a remarkable balance between performance and power efficiency. The CL40 (CAS Latency 40) timing, while numerically higher than DDR4 modules, represents an actual reduction in absolute latency when accounting for the increased clock speed. Additional timing parameters include tRCD (RAS to CAS Delay), tRP (RAS Precharge Time), and tRAS (Active to Precharge Delay), all optimized for server workload characteristics.
Physical Dimensions and Compatibility
The module utilizes the standard 288-pin RDIMM form factor, measuring 133.35mm in length with a standard height profile compatible with most server chassis designs. The carefully engineered PCB layout incorporates multiple signal integrity features, including optimized trace routing, controlled impedance, and enhanced power delivery networks. The module is designed to meet JEDEC specification requirements and is validated for compatibility with major server platforms from leading manufacturers.
ECC and Registered Technology Benefits
Error Correcting Code (ECC) Implementation
The Hynix HMCG84MEBRA115N incorporates advanced ECC technology that provides single-error correction and double-error detection capabilities. This sophisticated error correction mechanism is essential for maintaining data integrity in mission-critical server environments. The ECC implementation can detect and correct single-bit errors automatically, while identifying multi-bit errors to prevent data corruption. This level of protection is particularly valuable in applications involving financial transactions, database management, and scientific computing where data accuracy is non-negotiable.
Registered DIMM Architecture
As a Registered DIMM (RDIMM), this memory module includes registered clock drivers and data buffers that reduce the electrical load on the memory controller. This buffering enables support for higher memory capacities per channel and improves signal integrity in systems with multiple DIMMs per channel. The registered architecture allows for more stable operation at high frequencies and greater memory scalability, making the HMCG84MEBRA115N ideal for memory-intensive server configurations requiring large total memory capacities.
Reliability and Data Integrity Features
Beyond basic ECC functionality, the Hynix HMCG84MEBRA115N incorporates additional reliability enhancements including temperature sensors for thermal monitoring, parity protection for command and address signals, and advanced error logging capabilities. These features work in concert to provide comprehensive protection against various types of memory errors, ensuring system stability and minimizing the risk of unplanned downtime in enterprise environments.
Performance and Bandwidth
Bandwidth Improvements Over Previous Generations
The transition to DDR5 technology brings substantial bandwidth improvements, with the Hynix HMCG84MEBRA115N delivering approximately 1.5x the bandwidth of equivalent DDR4 modules. The 4800MHz operating frequency, combined with DDR5's architectural enhancements, enables higher sustainable transfer rates across a wide range of workload types. This increased bandwidth directly translates to improved application performance, particularly in memory-bound scenarios such as virtualization, in-memory databases, and high-performance computing applications.
Real-World Performance Metrics
In practical server deployments, the Hynix HMCG84MEBRA115N demonstrates significant performance advantages across multiple workload categories. Database applications show reduced query times, virtualization platforms support higher virtual machine densities, and scientific computing applications experience faster computation cycles. The improved memory efficiency also reduces CPU wait states, allowing processors to maintain higher utilization levels and complete tasks more efficiently.
