Product Description
The Dell A21327987 is a 4GB DDR3 Registered DIMM (RDIMM) memory module designed to enhance the performance and capacity of compatible Dell servers and workstations. Operating at a frequency of 1333MHz, it offers a significant improvement in data throughput compared to lower-speed memory, making it suitable for memory-intensive applications. The RDIMM architecture includes onboard registers that buffer address and command signals, reducing the electrical load on the memory controller and allowing for greater memory expansion and stability. This module is configured as 2Rx4, meaning it comprises two ranks of memory chips, with each rank having four internal banks. This dual-rank design can offer performance benefits in certain workloads by allowing the memory controller to interleave operations between ranks. The CAS Latency (CL) of 9 clock cycles dictates the delay between the memory controller issuing a read command and the data becoming available, a standard specification for DDR3 modules of this speed. With its combination of capacity, speed, and registered architecture, the A21327987 is a reliable choice for upgrading or populating memory in enterprise-grade systems. It supports Error-Correcting Code (ECC) functionality, which is crucial for maintaining data integrity in critical server environments by detecting and correcting single-bit errors.
