Dell A12978381 1GB DDR3-1333MHz UDIMM 1Rx8 CL9 Memory

Product Description

The Dell A12978381 is a 1GB memory module utilizing DDR3 technology, specifically in an Unbuffered DIMM (UDIMM) format. This type of memory is commonly found in desktop computers and entry-level workstations where the primary focus is on providing sufficient RAM for general computing tasks. DDR3 represents a significant step up from DDR2, offering higher clock speeds and improved power efficiency, which contributes to better overall system performance and responsiveness. Operating at a frequency of 1333MHz, this module provides a respectable data transfer rate suitable for everyday applications such as web browsing, office productivity suites, and light multimedia tasks. The CAS Latency (CL) of 9 clock cycles is a measure of the delay between the memory controller requesting data and the data being available. This latency, combined with the 1333MHz speed, defines the module's performance characteristics for its intended use. The 1Rx8 rank configuration indicates a single rank of memory chips, with each chip having an 8-bit data width. As an UDIMM, it does not feature error correction capabilities (non-ECC), making it generally less expensive and suitable for systems where data integrity is not as critical as in server environments. The Dell part number A12978381 ensures compatibility with specific Dell systems, although it may also be compatible with other brands of computers that support DDR3 1333MHz UDIMMs.
