Dell A21327979 1GB DDR3-1333MHz UDIMM 1Rx8 CL9 Memory

Product Description

The Dell A21327979 is a 1GB memory module that utilizes DDR3 SDRAM technology, operating at a frequency of 1333MHz. This speed, often referred to as PC3-10600, provides a substantial increase in data transfer rates compared to previous DDR generations, contributing to overall system responsiveness and performance. The module is an Unbuffered DIMM (UDIMM), which means it does not incorporate an onboard buffer chip, making it suitable for a wide range of standard desktop and server applications where direct memory access is preferred. With a CAS Latency (CL) of 9, this memory module strikes a balance between speed and timing, ensuring efficient data retrieval from the memory banks. The 1Rx8 organization indicates that it is a single-rank module with an eight-bit data width per chip, a common configuration for modules of this capacity and speed. The standard operating voltage for DDR3 is 1.5V, which this module adheres to, ensuring compatibility with systems designed for this voltage standard. This specific memory module is identified by Dell's part number A21327979, suggesting it is intended for use in Dell branded computer systems, including desktops, workstations, and potentially entry-level servers. Upgrading or replacing memory with modules like this can significantly improve multitasking capabilities, application load times, and the overall smooth operation of the computer, especially in systems that may have come with lower amounts of RAM.
