Technical Specifications of the Hynix HMCG84MEBRA DDR5 RDIMM

Capacity and Performance Speed

The 32GB capacity of this DDR5-4800 RDIMM ensures servers can handle memory-intensive applications, in-memory databases, and complex workloads with ease. Operating at a high-speed 4800 MT/s (megatransfers per second), equivalent to PC5-38400 bandwidth, the module provides fast data throughput, reducing bottlenecks and enhancing responsiveness in data-heavy operations. The CL40 latency ensures balanced performance, allowing applications to access memory quickly while maintaining system efficiency.

ECC and Registered Buffer Functionality

Error-Correcting Code (ECC) is a critical feature for server-grade memory, ensuring data integrity by detecting and correcting single-bit errors in real time. The registered buffer, also known as RDIMM functionality, improves signal integrity by reducing the electrical load on the memory controller, allowing more memory modules to be installed without compromising stability. This combination of ECC and RDIMM architecture enhances overall system reliability, making the HMCG84MEBRA ideal for mission-critical workloads where downtime is unacceptable.

Form Factor and Voltage Efficiency

Featuring a 288-pin RDIMM form factor, this Hynix module is compatible with a wide range of modern server platforms supporting DDR5 technology. The memory operates at a standard DDR5 voltage of 1.1V, reducing overall power consumption while minimizing heat generation. This efficiency is particularly beneficial for data centers and enterprise IT environments that require scalable and energy-conscious memory solutions.
