Dell A21427972 2GB DDR3-1066MHz RDIMM 2Rx8 CL7 Memory

Product Description

The Dell A21427972 is a 2GB memory module that utilizes DDR3 Synchronous Dynamic Random-Access Memory (SDRAM) technology. Designed for compatibility with specific Dell server and workstation models, this module operates at a frequency of 1066MHz, providing adequate performance for systems that were designed with this generation of memory. The 2GB capacity is suitable for entry-level server tasks or for systems where memory requirements are not extensive. This module is an RDIMM (Registered DIMM), which includes a register chip that buffers command and address signals. This buffering reduces the electrical load on the memory controller, allowing for more memory modules to be installed in a system and enhancing overall stability, particularly in server environments where high memory capacities are common. The 2Rx8 organization indicates that the module has two ranks, each with an x8 data width, which can contribute to performance by allowing for more parallel operations. The module features a CAS Latency (CL) of 7. This timing parameter indicates the number of clock cycles required to access a particular memory column. Lower CL values generally mean faster access times. Importantly, this module supports ECC (Error-Correcting Code) functionality. ECC memory can detect and correct common types of internal data corruption, which is crucial for maintaining data integrity and system reliability in server and workstation applications. This makes the A21427972 a dependable choice for systems requiring stable and error-free operation.
