Description
The Dell A21627989 is a 4GB DDR3 Registered DIMM (RDIMM) memory module, designed to enhance the performance and stability of compatible Dell servers and workstations. Operating at a speed of 1333MHz, this module provides a substantial increase in memory capacity and bandwidth, which is essential for running multiple applications, virtual machines, and handling large datasets. This RDIMM features a 2Rx4 configuration, meaning it consists of two ranks of memory chips, with each chip organized as four data bits. The 'Registered' nature of the module includes an onboard register that buffers the command and address signals, reducing the electrical load on the memory controller. This allows for greater memory density and improved system stability, making RDIMMs a preferred choice for enterprise-grade systems where reliability is critical. With a CAS Latency (CL) of 9, the A21627989 offers efficient data access times. This memory module is an excellent option for upgrading existing server infrastructure or for building new systems that require a balance of capacity, performance, and reliability. It is crucial to confirm system compatibility, as RDIMMs are specifically designed for server environments and may not be compatible with standard desktop motherboards.
