Technical Specifications and Architecture

High-Capacity 96GB Design

With a massive 96GB per module, this RDIMM reduces the number of DIMMs required in server configurations while maximizing available memory. Fewer DIMMs per server improve airflow and thermal management, lower power consumption, and simplify system expansion. The high-density configuration is ideal for virtualization, large-scale database management, cloud computing environments, and data-intensive AI workloads.

DDR5 PC5-44800 5600MHz Speed

The module operates at DDR5-5600MHz, providing a maximum bandwidth of PC5-44800. Compared to DDR4, DDR5 offers improved data rates, reduced latency in sustained workloads, and greater overall efficiency. This speed enhancement is particularly beneficial for workloads that rely on high-throughput memory operations, including AI training, large-scale simulations, and real-time analytics.

CL46 Latency Optimization

Featuring a CAS latency (CL) of 46, the module is optimized to balance high-speed performance with low-latency access. While latency is slightly higher than previous DDR4 modules, the significantly increased bandwidth of DDR5 offsets this, ensuring superior real-world performance for multi-threaded and memory-intensive applications.

ECC (Error-Correcting Code) Reliability

The integrated ECC technology detects and corrects single-bit errors, preventing data corruption and system crashes. This feature is essential for industries where reliability is critical, such as finance, healthcare, government, and cloud service providers. ECC support ensures continuous operation and data integrity under heavy workloads.

288-Pin Registered DIMM (RDIMM)

The module’s 288-pin RDIMM architecture includes a register buffer that minimizes electrical load on the memory controller. This allows multiple modules to be installed in servers without compromising signal integrity, ensuring stable performance even at large-scale memory capacities.

Dual-Rank Configuration

The dual-rank (2Rx4) structure optimizes memory channel utilization, increasing effective bandwidth and access efficiency. This configuration enables servers to maintain high performance in multi-core processing environments and parallelized workloads.

DDR5 Technology Enhancements

Increased Bandwidth for Modern Workloads

DDR5 technology provides nearly double the bandwidth of DDR4, and the HMCGM4MGBRB’s 5600MHz speed ensures high data throughput. This capability is critical for applications like AI training, machine learning inference, high-frequency trading, and enterprise virtualization, which require rapid data access and processing.

On-Die ECC for Internal Error Correction

In addition to external ECC, DDR5 features on-die ECC that corrects minor internal memory errors before they reach the system level. This dual-layer error correction enhances reliability, especially in high-capacity, high-performance environments.

Dual Subchannel Architecture

DDR5 modules split each DIMM into two independent 32-bit subchannels, allowing for parallel memory access. This design reduces latency, improves memory utilization, and provides consistent performance across multi-core server processors.

Integrated Power Management IC (PMIC)

DDR5 modules like the HMCGM4MGBRB integrate PMICs, enabling improved voltage regulation directly on the module. This reduces overall power consumption, improves energy efficiency, and ensures stable performance under varying workloads, helping data centers reduce operational costs and environmental impact.

Workload Applications

Database Servers and Analytics

High-capacity database workloads, such as Oracle, SQL Server, PostgreSQL, and in-memory platforms like SAP HANA, benefit from the module’s high-speed DDR5 memory. It improves query execution times, enables larger in-memory datasets, and supports real-time analytics with minimal latency.

High-Performance Computing (HPC)

HPC clusters used in scientific simulations, engineering modeling, and climate prediction require robust memory modules. The HMCGM4MGBRB’s ECC reliability, high bandwidth, and low-latency design ensure stable performance across thousands of parallel processes.

Enterprise Applications

From ERP solutions to real-time transaction processing, this module supports continuous uptime for mission-critical enterprise software. The combination of high capacity, ECC protection, and fast DDR5 performance ensures business operations remain reliable and efficient.

Reliability and Stability Features

ECC and On-Die ECC

Dual-layer error correction protects data from corruption, ensuring high reliability in financial systems, healthcare databases, and government infrastructures. Single-bit errors are automatically detected and corrected, preventing downtime and maintaining operational integrity.

Thermal Sensors and Monitoring

Integrated thermal monitoring enables proactive cooling management. Data centers can monitor memory temperature and adjust airflow or cooling systems to maintain optimal performance, preventing overheating in dense rack environments.

Registered DIMM Buffering

The RDIMM register buffer improves signal integrity, enabling reliable performance even when multiple modules are installed across memory channels. This is critical in servers with high-density memory configurations.

Deployment Best Practices

Server Compatibility

The HMCGM4MGBRB is compatible with servers designed for DDR5 RDIMM memory. Ensure BIOS and firmware are updated to support 5600MHz modules for optimal performance.

Balanced DIMM Population

For maximum performance, memory modules should be installed in matched pairs or across balanced channels. This ensures optimal bandwidth utilization and system stability.

Cooling and Power Management

Although DDR5 reduces power consumption compared to DDR4, 96GB modules in high-density configurations require adequate cooling and power planning. Proper airflow and server layout help prevent thermal throttling.

Industry-Specific Use Cases

Financial Sector

Low-latency, high-bandwidth memory is critical for trading platforms, fraud detection, and real-time transaction systems. ECC support ensures that financial data remains accurate and secure.
