R9Q19A-ACC Overview

The R9Q19A-ACC is a 64GB DDR5-4800MHz (PC5-38400) ECC Registered RDIMM from Accortec, specifically engineered as a high-performance, guaranteed compatible alternative to the HPE factory original part (R9Q19A). Operating at a power-efficient 1.1V, this 288-pin module leverages the advanced architecture of DDR5 technology to provide a substantial increase in memory bandwidth and data transfer efficiency for next-generation HPE ProLiant Gen11 servers and storage platforms.
As an ECC Registered module, it features an onboard register to buffer command and address signals, reducing the electrical load on the memory controller and allowing for greater system stability in high-capacity configurations. The integrated Error-Correcting Code (ECC) technology proactively detects and repairs single-bit data errors, ensuring the mission-critical reliability and data integrity required for enterprise-level workloads. This 64GB module is an ideal solution for scaling memory density in environments running intensive applications such as large-scale virtualization, cloud infrastructure, and real-time data analytics, providing a cost-effective way to maximize server performance without compromising OEM-level quality standards.
