Dell A21378381 1GB DDR3-1333MHz UDIMM 1Rx8 CL9 Memory

Description

The Dell A21378381 is a 1GB DDR3 Unbuffered DIMM (UDIMM) memory module, designed to provide essential memory capacity for a range of Dell computer systems, including desktops and potentially entry-level servers. DDR3 technology represented a significant step forward from DDR2, offering higher speeds and improved power efficiency. This module operates at a frequency of 1333MHz, which translates to a PC3-10600 data transfer rate, providing adequate bandwidth for everyday computing tasks and standard business applications. The module features a CAS Latency (CL) of 9, indicating the number of clock cycles required for the memory to access data after a command is issued. The 1Rx8 configuration signifies a single-rank module with eight memory chips per rank, a common and efficient design for this capacity. As an unbuffered DIMM, it does not have a register chip, making it suitable for systems that can directly handle the signal load from the memory controller, which is typical for many consumer and some professional systems. Operating at the standard DDR3 voltage of 1.5V, the A21378381 is compatible with motherboards that support DDR3 memory. Its 1GB capacity, while modest by today's standards, was a common configuration for system upgrades or base configurations in its era. This module serves as a reliable component for systems requiring basic memory expansion or replacement, ensuring continued functionality for users of compatible Dell hardware.
