Product Description
The Dell A21427992 is a 4GB DDR3 Registered DIMM (RDIMM) memory module, specifically designed for server and high-end workstation environments that require enhanced memory reliability and stability. This module operates at a speed of 1333MHz (PC3-10600R) and features a CAS latency of CL9, providing efficient data access. The 'R' in PC3-10600R signifies that it is a registered module, which includes a register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and more modules per channel. This RDIMM is configured as 2Rx4, meaning it has two ranks, and each rank uses x4 memory chips. This configuration is common in server memory and can offer performance benefits in certain multi-processor or high-density memory configurations. Crucially, the Dell A21427992 supports ECC (Error-Correcting Code) functionality. ECC memory can detect and correct common types of internal data corruption, significantly reducing the risk of data errors and system crashes, which is vital for mission-critical applications and continuous operation environments. Operating at a standard voltage of 1.5V, this 4GB DDR3 RDIMM is a reliable choice for upgrading or populating memory in compatible Dell servers and other enterprise-grade systems. Its registered nature and ECC capabilities make it suitable for demanding workloads where data integrity and system uptime are paramount. Always ensure compatibility with your specific server model and motherboard specifications before purchasing.
