M321RAGA0B20-CWKPJ Samsung 128gb 288-pin Rdimm Memory Module

M321RAGA0B20-CWKPJ Overview

The Samsung M321RAGA0B20-CWKPJ is a 128GB DDR5 ECC Registered DIMM (RDIMM) built to deliver exceptional capacity and reliability for next-generation servers and enterprise systems. Operating at 4800MT/s (PC5-38400) with a CAS Latency of CL40, this module ensures outstanding memory bandwidth and responsiveness to handle data-intensive workloads.
Designed with a quad-rank x4 (4Rx4) architecture, it maximizes scalability and memory density for heavy enterprise applications such as virtualization, cloud computing, AI/ML, and large-scale databases. The ECC (Error-Correcting Code) functionality provides robust data integrity, while registered buffering enhances stability and allows support for large memory configurations in demanding server environments. Running at an efficient 1.1V, it balances high performance with reduced power consumption.
