R9Q20A HPE 128gb 1.1v Ddr5 Sdram 288-pin Rdimm Standard Memory Kit

R9Q20A Overview

The HPE R9Q20A is a 128GB DDR5 ECC Registered DIMM (RDIMM) designed to deliver high-capacity, reliable, and efficient memory performance for enterprise-class HPE servers. Running at 4800MT/s (PC5-38400) with a CAS latency of CL42, this module provides the bandwidth and responsiveness required for today’s most demanding datacenter workloads, including virtualization, large-scale databases, AI/ML processing, and cloud infrastructure.
This module uses a Quad Rank x4 architecture, offering a balance between performance and memory density. With ECC (Error-Correcting Code) and Registered (buffered) technology, it ensures system stability and data integrity, minimizing downtime in mission-critical environments. The module operates at a low 1.1V, optimizing energy efficiency while maintaining high throughput.
