Dell A21328001 2GB DDR3-1333MHz UDIMM 2Rx8 CL9 Memory

Product Description

The Dell A21328001 is a 2GB DDR3 Unbuffered DIMM (UDIMM) memory module, suitable for upgrading or expanding the memory capacity of standard desktop computers and entry-level servers. It operates at a frequency of 1333MHz, providing a good balance of performance for everyday computing tasks and applications. The module features a CAS Latency (CL) of 9, indicating the number of clock cycles required to access data, which is a common specification for DDR3 memory operating at this speed. This UDIMM is configured as 2Rx8, meaning it is a dual-rank module with memory chips organized as x8. Dual-rank modules can offer performance advantages in certain system architectures by allowing the memory controller to access different ranks of memory, potentially increasing bandwidth. Unbuffered DIMMs directly connect to the memory controller without intermediate registers, making them generally less expensive and suitable for systems where memory capacity requirements are moderate. Crucially, this module is Non-ECC (Error-Correcting Code). This means it does not have the built-in capability to detect and correct memory errors, which is standard for consumer-grade systems but less common in high-reliability server environments that require ECC memory. The A21328001 operates at a standard voltage of 1.5V and is designed for compatibility with motherboards that support DDR3 UDIMM memory.
