Technical Specifications and Design

96GB High-Capacity Memory Module

With an impressive 96GB density, the HMCGM4MEBRB248N reduces the number of DIMMs required per server, thereby decreasing energy consumption and system complexity. Fewer DIMMs not only improve cooling efficiency but also reduce the risk of system instability caused by overcrowded slots. This large capacity is critical for enterprise workloads like virtualization, SAP HANA, Oracle databases, and advanced AI models.

DDR5 PC5-38400 with 4800MHz Frequency

Operating at DDR5-4800MHz, the HMCGM4MEBRB248N achieves a maximum theoretical bandwidth of PC5-38400. This allows applications to benefit from faster data throughput, reduced latency, and improved efficiency compared to DDR4. Enterprises running big data analytics, machine learning workloads, and large-scale simulations gain noticeable performance benefits.

CL40 Latency Optimization

Featuring a CAS latency (CL) of 40, this memory module ensures balanced performance for high-throughput workloads. While latency is slightly higher than DDR4, the increased bandwidth of DDR5 offsets this difference, making it ideal for applications that rely on sustained data flow rather than minimal single-access delays.

ECC for Error-Free Performance

The ECC (Error-Correcting Code) functionality ensures robust data integrity by detecting and correcting single-bit memory errors. In mission-critical environments such as banking, government IT, and healthcare, ECC protection reduces downtime risks and maintains data accuracy even under high-load conditions.

2Rx4 Rank Configuration

The 2Rx4 dual-rank structure improves system performance by distributing memory access across multiple ranks. This allows for better efficiency and throughput, particularly in multi-threaded and parallel processing tasks where data lanes must remain consistently active.

288-Pin Registered DIMM

As a 288-pin RDIMM, the HMCGM4MEBRB248N uses a register buffer to maintain stable signal integrity between the CPU and memory. This architecture is essential when deploying large memory modules across servers, ensuring consistent performance even at maximum capacity.

Key Benefits of DDR5 Technology

Enhanced Bandwidth for Data-Intensive Workloads

DDR5 offers nearly double the bandwidth of DDR4. With 4800MHz speed, this module is particularly advantageous for data-intensive applications like AI training, high-frequency trading, and enterprise-level virtualization platforms that demand sustained throughput.

Improved Power Management

DDR5 introduces Power Management IC (PMIC) integration, allowing power regulation directly on the module. This improves efficiency, reduces voltage fluctuations, and supports stable performance under varying workloads.

On-Die ECC for Internal Error Correction

DDR5’s on-die ECC works alongside external ECC, providing a dual layer of protection against data corruption. This feature is particularly important in large memory deployments where reliability is paramount.

Dual Subchannel Architecture

By splitting each DIMM into two independent 32-bit subchannels, DDR5 enables parallel data access, enhancing memory efficiency and reducing bottlenecks. For multi-core processors, this architecture significantly boosts performance.

Use Cases for HMCGM4MEBRB248N

Database Servers

Applications like Oracle, SQL Server, and PostgreSQL benefit from memory-rich configurations. The HMCGM4MEBRB248N reduces query response times, enables larger in-memory databases, and supports real-time analytics.
