Dell A21427475 1GB DDR3-1333MHz UDIMM 1Rx8 CL9 Memory

Description

The Dell A21427475 is a 1GB DDR3 Unbuffered DIMM (UDIMM) memory module, intended for use in standard desktop computers and entry-level servers. It operates at a frequency of 1333MHz, providing adequate performance for basic computing tasks and older systems. The module features a CAS Latency (CL) of 9, which is a standard timing parameter for DDR3 memory operating at this speed, ensuring efficient data access for general use. This UDIMM is configured as 1Rx8, indicating it is a single-rank module with memory chips organized as x8. Single-rank modules are common for lower-capacity DIMMs and are directly connected to the memory controller. Unbuffered DIMMs do not have onboard registers, which typically results in lower power consumption and cost compared to Registered DIMMs (RDIMMs), making them suitable for mainstream consumer and business PCs. This module is Non-ECC (Non-Error-Correcting Code), meaning it lacks the error detection and correction capabilities found in ECC memory. This is standard for most desktop systems where the cost-benefit analysis favors non-ECC modules. The A21427475 operates at the standard DDR3 voltage of 1.5V and is designed for compatibility with motherboards that support DDR3 UDIMM memory specifications.
