Dell A21378428 1GB DDR3-1333MHz UDIMM 1Rx8 CL9 Memory

Product Description

The Dell A21378428 is a 1GB memory module that employs DDR3 Synchronous Dynamic Random-Access Memory (SDRAM) technology, operating at a frequency of 1333MHz (PC3-10600). This module is an Unbuffered DIMM (UDIMM), meaning it does not include an onboard register to buffer signals. UDIMMs are commonly used in a broad range of computing devices, including desktops, workstations, and entry-level servers, where the memory controller can directly manage the electrical load. The 1GB capacity is suitable for basic system operations and less memory-intensive applications. This module is configured as 1Rx8. The '1R' designation indicates that it is a single-rank module, meaning it has one set of memory chips (rank) that the memory controller accesses. The 'x8' specifies that each DRAM chip on the module has an 8-bit data width. Single-rank modules are typically less complex and can be more cost-effective. The CAS Latency (CL) is rated at 9, which refers to the number of clock cycles required for the memory module to respond to a column access command. This 1GB DDR3-1333MHz UDIMM is designed for installation in compatible Dell systems that support this memory specification. It serves as a fundamental component for systems performing basic computing tasks, ensuring the operating system and essential applications have sufficient memory to function. Verification of system compatibility with UDIMMs, DDR3 technology, and the specified speed and capacity is recommended prior to installation.
