Key Specifications of HMCG94MEBQA109N DDR5 RDIMM

High Capacity 64GB Module

With 64GB capacity, this DDR5 RDIMM allows administrators to deploy higher-density memory in each server slot. This density is ideal for virtualization clusters, in-memory databases, and AI training workloads that demand massive RAM availability.

DDR5 4800MHz Performance

The 4800MHz frequency delivers faster bandwidth compared to DDR4 modules, ensuring efficient handling of modern multi-threaded server applications. With PC5-38400 data transfer rates, the module achieves bandwidth up to 38.4GB/s, supporting seamless processing of heavy workloads.

ECC Reliability and Data Integrity

The inclusion of ECC (Error-Correcting Code) functionality ensures that transient memory errors are automatically corrected, reducing downtime and safeguarding mission-critical data. ECC reliability is indispensable for industries like healthcare, finance, and defense, where data accuracy is a top priority.

2Rx4 Rank Structure

The 2Rx4 rank configuration improves memory efficiency and bandwidth utilization by allowing multiple ranks to operate concurrently. This enables higher throughput and consistent performance under demanding workloads.

288-Pin RDIMM Format

The 288-pin Registered DIMM design ensures compatibility with enterprise-grade server motherboards supporting DDR5 memory. The RDIMM structure provides stability for high-density memory arrays by using a register buffer to reduce electrical load on the memory controller.

Advantages of DDR5 Server Memory Technology

Higher Bandwidth and Faster Performance

DDR5 offers substantially improved performance over DDR4. The HMCG94MEBQA109N module’s 4800MHz clock speed enables servers to process larger workloads, support more users, and deliver faster computational results for AI and HPC workloads.

Enhanced Reliability with On-Die ECC

Beyond module-level ECC, DDR5 integrates on-die ECC, correcting errors inside the DRAM chip before they propagate. This dual-layer error correction system further improves uptime and prevents application crashes.

Power Efficiency

DDR5 operates at just 1.1V, consuming less power while maintaining high throughput. Integrated Power Management ICs (PMICs) regulate voltage at the module level, improving efficiency and reducing thermal output in large server deployments.

Greater Memory Density

DDR5 technology doubles density potential compared to DDR4. As a result, servers can scale to terabyte-level memory capacities, unlocking new levels of performance in enterprise computing environments.

Enterprise Workload Applications

Big Data and Analytics

Modern analytics platforms process terabytes of data in real time. This 64GB DDR5 module supports applications like Apache Spark, SAP HANA, and Hadoop by ensuring smooth query execution and reduced bottlenecks.

High-Performance Computing (HPC)

From scientific research to engineering simulations, HPC workloads require both capacity and bandwidth. The HMCG94MEBQA109N delivers ECC-protected, high-throughput memory performance essential for stable and accurate results.

Database Workloads

Enterprise databases such as Oracle, SQL Server, and MySQL benefit from large in-memory datasets. With 64GB per module, database query speeds improve, and transaction latency decreases, resulting in enhanced application responsiveness.

Reliability Features

ECC Error Protection

ECC functionality prevents data corruption, ensuring mission-critical workloads operate without interruption. This is crucial in financial transactions, patient healthcare records, and government applications.

Thermal Sensors

Integrated thermal sensors provide real-time monitoring, helping administrators optimize cooling strategies and prevent thermal throttling.
