ECC and Registered Features

This module incorporates both Error Correcting Code (ECC) and Registered buffer technology. ECC functionality detects and corrects single-bit memory errors automatically, preventing data corruption and system crashes. The Registered (buffered) design includes address and command buffers that reduce electrical load on the memory controller, enabling support for higher memory capacities and improved signal integrity in multi-module configurations.

Dual Rank Architecture

The dual rank design allows for better memory controller utilization by organizing the memory into two separate addressable sections. This architecture improves memory access efficiency and increases overall system performance by enabling better parallelism in memory operations. The dual rank configuration is particularly beneficial in server environments where multiple memory access patterns occur simultaneously.

x4 DRAM Device Organization

Utilizing x4 DRAM organization, this module provides optimal data bus utilization and enhanced reliability. The x4 configuration (4-bit wide DRAM devices) supports enhanced chipkill functionality and improves error correction capabilities. This organization is specifically designed for server applications where data integrity and fault tolerance are paramount concerns.

Operating Voltage and Power

Operating at 1.2V, the module adheres to DDR4 standard voltage specifications, providing improved power efficiency compared to previous generations. The lower voltage requirement reduces overall power consumption and heat generation, contributing to better system stability and reduced cooling requirements in data center environments. Power management features include advanced power-down modes and temperature-controlled refresh rates.

Performance and Reliability Features

Error Correction and Data Integrity

The ECC implementation on the HMAG84EXNRA084N provides single-error correction and double-error detection capabilities. This advanced error correction goes beyond basic ECC by incorporating additional parity checking and error logging features. The module can detect multiple bit errors within the same memory word and correct single-bit errors transparently to the operating system and applications.

Registered DIMM Advantages

The Registered DIMM design incorporates address and command registers that buffer signals between the memory controller and DRAM devices. This buffering reduces the electrical load on the memory controller, enabling support for more memory modules per channel and higher total memory capacities. The registered design also improves signal integrity at higher speeds and in systems with large memory configurations.

Server Platform Compatibility

The HMAG84EXNRA084N is compatible with a wide range of server platforms including Intel Xeon Scalable processors, AMD EPYC systems, and other server-class processors that support DDR4 RDIMM memory. The module is designed to work with server chipsets that support registered ECC memory and can operate at 3200MT/s speeds with appropriate processor and BIOS support.

Application and Use Cases

Data Center and Cloud Infrastructure

This memory module is ideally suited for data center deployments where reliability, scalability, and performance are critical. Applications include virtualized environments, database servers, cloud computing infrastructure, and large-scale web hosting platforms. The ECC protection ensures data integrity for critical business applications and customer data.

High-Performance Computing

In HPC environments, the HMAG84EXNRA084N provides the necessary memory capacity and bandwidth for scientific computing, engineering simulations, and research applications. The module's reliability features ensure extended computation jobs can complete without memory-related errors, while the registered design supports the large memory configurations required by complex computational workloads.

Specialized Server Workloads

For database servers and online transaction processing systems, this memory module offers the combination of capacity and reliability needed for handling large datasets and high transaction volumes. The ECC functionality protects against data corruption in memory-resident databases, while the registered design supports the dense memory configurations typical of modern database servers.

Virtualization and Container Platforms

In virtualized environments, the 32GB module capacity allows for efficient memory allocation across multiple virtual machines. The memory module's reliability features are particularly valuable in consolidation scenarios where multiple workloads share physical hardware, ensuring that memory errors in one virtual machine don't affect others on the same host.
