Samsung M393AAG40M3B-CYFC0 128GB DDR4-2933MHz RDIMM 4Rx4 CL21 Memory

Description

The Samsung M393AAG40M3B-CYFC0 is a high-performance 128GB DDR4 Registered DIMM (RDIMM) memory module, engineered for server and workstation environments that demand substantial memory capacity and reliability. Operating at a frequency of 2933MHz, it provides excellent bandwidth for data-intensive applications, virtualization, large databases, and complex computational tasks. The RDIMM form factor includes an onboard register that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved stability in multi-module configurations. This module features a 4Rx4 rank organization, meaning it utilizes four ranks of memory chips, each with an x4 data width. This configuration is often employed in high-capacity modules to achieve the total density while potentially offering performance benefits in certain memory access patterns. The CAS Latency (CL) of 21 indicates the number of clock cycles required for the memory to respond to a column address command. While higher latency, the speed and capacity often outweigh this in server workloads where throughput is prioritized. As an ECC (Error-Correcting Code) memory module, the M393AAG40M3B-CYFC0 can detect and correct common types of internal data corruption, significantly enhancing data integrity and system reliability. This is a critical feature for mission-critical applications where data accuracy and uptime are paramount. With its substantial capacity, high speed, and robust features, this Samsung memory module is an ideal choice for upgrading or populating servers and workstations designed to handle demanding workloads.
