Dell A21427991 4GB DDR3-1333MHz RDIMM 2Rx4 CL9 Memory

Description

The Dell A21427991 is a 4GB DDR3 Registered DIMM (RDIMM) memory module, engineered to deliver enhanced performance and stability for Dell server systems. With its 4GB capacity, it provides ample memory for demanding applications, virtualization, and data-intensive workloads. The DDR3 technology ensures efficient data throughput, while the 1333MHz operating speed facilitates quick access to data, crucial for maintaining system responsiveness. This module is a Registered DIMM, meaning it includes an onboard register that buffers command and address signals. This buffering mechanism reduces the electrical load on the memory controller, allowing for greater memory capacity and improved system stability, especially in multi-processor or high-density server environments. The 2Rx4 configuration indicates that the module comprises two ranks of memory chips, each with an x4 data interface, contributing to its overall performance and capacity. The A21427991 features a CAS Latency (CL) of 9, defining the number of clock cycles between the memory controller issuing a read command and the data becoming available. Furthermore, it supports ECC (Error-Correcting Code) functionality, which is vital for detecting and correcting single-bit errors and detecting multi-bit errors, thereby ensuring data integrity and system reliability in critical applications. This combination of features makes it a robust choice for enterprise-grade computing.
