Description
The Dell A21627990 is a 4GB Registered Dual In-line Memory Module (RDIMM) operating at a speed of 1333MHz. This memory module is specifically designed for use in enterprise-grade servers and workstations that support DDR3 RDIMM technology. The 'Registered' aspect of the module helps to reduce electrical load on the memory controller, allowing for higher memory capacities and improved system stability, which is critical in server environments. With a 2Rx4 configuration (Dual Rank x4), this module offers enhanced performance by allowing the memory controller to access different ranks of memory simultaneously. The CAS Latency of CL9 indicates the number of clock cycles required to access a particular column in a row, contributing to the overall responsiveness of the system. This specification is crucial for applications that are sensitive to memory latency. This 4GB DDR3-1333MHz RDIMM is an ideal component for upgrading existing Dell systems or for populating new server builds to meet the memory requirements of modern operating systems and applications. Ensuring compatibility with the specific Dell server model is recommended before installation to guarantee optimal performance and stability.
