Memory Architecture

The HMA81GR7AFR8N-UH utilizes advanced DDR4 SDRAM technology with registered (buffered) architecture. This registered design incorporates a register between the memory controller and DRAM modules, which helps stabilize electrical signals and reduce loading on the memory controller. This architecture is particularly beneficial in systems with high memory densities or multiple memory modules, as it enables more stable operation and higher capacity configurations than unbuffered alternatives.

Performance Characteristics

With a data rate of 2400 million transfers per second (MT/s) and a PC4-19200 classification, this module delivers a peak bandwidth of 19.2 GB/s. The DDR4 architecture provides significant improvements over previous generations, including higher module densities, lower voltage requirements (1.2V), and enhanced data integrity features. These improvements translate to better power efficiency and thermal performance, critical factors in densely populated server environments.

Enterprise Server Environments

The Hynix HMA81GR7AFR8N-UH is ideally suited for general-purpose enterprise servers handling business applications, file sharing, and print services. Its reliable performance characteristics make it an excellent choice for servers requiring consistent operation with minimal downtime. The 8GB density provides a balance between capacity and cost-effectiveness for many mainstream server deployments.

Reliability

Hynix employs rigorous manufacturing processes and quality control measures to ensure the reliability of the HMA81GR7AFR8N-UH memory modules. Each module undergoes comprehensive testing at multiple stages of production, including wafer testing, module assembly verification, and final product validation. This multi-stage testing process helps identify potential issues before modules reach customers.

Thermal Management

The HMA81GR7AFR8N-UH features a standard profile that facilitates proper airflow in server configurations. While it does not include an integrated heat spreader, the module is engineered to operate reliably within standard server thermal environments. For applications with exceptional thermal requirements, ensure adequate system cooling to maintain optimal memory performance and longevity.

DDR4 Technology Advancements

DDR4 memory represents a significant evolution from previous DDR generations. Key advancements include higher data rates (starting at 2133MHz compared to DDR3's 1333MHz-1866MHz), reduced operating voltage (1.2V versus DDR3's 1.5V), and improved signal integrity through features like data bus inversion (DBI) and pseudo-open drain (POD) I/O. These improvements collectively enhance performance while reducing power consumption.

Registered DIMM Architecture

Registered DIMMs (RDIMMs) incorporate a register between the memory controller and DRAM chips. This register buffers command, address, and control signals, reducing the electrical load on the memory controller. This architecture enables support for more memory modules per channel and higher total memory capacities compared to unbuffered designs. The slight additional latency introduced by the register is typically negligible in server workloads where capacity and stability are prioritized.

DDR4 vs. DDR3 Memory

Compared to DDR3 memory, DDR4 offers several advantages including higher data rates, improved power efficiency, and increased module densities. The lower operating voltage (1.2V vs. 1.5V for DDR3) reduces power consumption and heat generation, particularly important in dense server configurations. The architectural improvements in DDR4 also provide better scalability for future performance requirements.

Compatibility

This memory module is specifically designed for server platforms that require registered DDR4 memory. It is compatible with a wide range of enterprise servers from major manufacturers including Dell PowerEdge, HPE ProLiant, Lenovo Think System, and Cisco UCS platforms. Additionally, it supports workstation platforms from manufacturers like Super micro, ASUS, and Gigabyte that utilize server-grade chipsets with registered memory support. The HMA81GR7AFR8N-UH is validated for use with Intel Xeon Scalable processors (Skylake, Cascade Lake, and compatible generations) as well as AMD EPYC processors that support registered DDR4 memory. The module's JEDEC-standard specifications ensure broad compatibility with server platforms that meet the technical requirements for 2400MHz DDR4 registered memory.
