Product Description
The Dell A21427974 is a 2GB DDR3 Registered DIMM (RDIMM) module, specifically designed and validated for use in Dell server and workstation environments. Operating at a speed of 1066MHz, it offers a good balance of capacity and performance for a wide range of enterprise applications. The RDIMM form factor includes a register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved signal integrity in multi-processor systems. This memory module features a 2Rx8 configuration, indicating it is dual-rank with memory chips organized as x8 (eight bits per chip). This configuration can enhance performance by allowing the memory controller to access different ranks concurrently. The module also supports ECC (Error-Correcting Code) functionality, which is essential for servers and workstations to detect and correct memory errors, thereby ensuring data integrity and system stability. With a CAS Latency (CL) of 7, the Dell A21427974 provides a responsive memory access time suitable for demanding server workloads. Its compatibility is primarily with Dell systems that support DDR3 RDIMMs at 1066MHz, making it a reliable choice for memory upgrades or replacements in compatible Dell PowerEdge servers or Precision workstations.
