HMA82GR7CJR4N-XN Hynix 16GB PC4-25600 DDR4-3200Mhz Memory Module

Hynix HMA82GR7CJR4N-XN 16GB DDR4 Server Memory

The Hynix HMA82GR7CJR4N-XN represents a high-performance 16GB DDR4 memory module engineered specifically for enterprise-level servers and workstations. This 1Rx4 ECC registered DIMM operates at PC4-25600 (DDR4-3200MHz) speeds with CL22 timings, delivering optimal performance for data-intensive applications while maintaining strict reliability standards.

Capabilities

Operating at 3200MT/s (Mega Transfers per second), this module provides a peak bandwidth of 25.6 GB/s in a single-channel configuration. HMA82GR7CJR4N-XN When deployed in multi-channel architectures common in modern servers, the aggregate bandwidth scales linearly, making it ideal for memory-bound applications such as database management, virtualization, and scientific computing.

Registered DIMM Architecture

This module utilizes registered (buffered) architecture where address and command signals pass through a register buffer before reaching the DRAM chips. This reduces electrical load on the memory controller, enabling higher module densities and more stable operation in multi-DIMM configurations typical of server platforms.

Thermal Management

The module includes temperature sensors and supports thermal throttle mechanisms to prevent overheating in dense server configurations. While it doesn't require active cooling in properly ventilated chassis, HMA82GR7CJR4N-XN adequate airflow is essential for maintaining optimal performance and reliability in high-ambient-temperature environments.

Reliability

Hynix manufactures this module to enterprise standards with rigorous testing and validation processes. The components undergo extended burn-in testing and are rated for 24/7 operation in controlled data center environments with typical MTBF (Mean Time Between Failures) exceeding 2 million hours.

Firmware

The module includes a comprehensive SPD chip containing JEDEC-standard timing parameters for HMA82GR7CJR4N-XN multiple operating speeds, manufacturer information, serial number, and module characteristics. System BIOS uses this information to automatically configure optimal settings during boot.

DDR4 vs. DDR5 Memory

While DDR5 offers higher theoretical bandwidth, DDR4-3200 remains a cost-effective solution for many enterprise deployments. The mature DDR4 ecosystem provides proven reliability, broader compatibility, and favorable total cost of ownership for existing infrastructure.
