Dell A21328002 2GB DDR3-1333MHz UDIMM 2Rx8 CL9 Memory

Product Description

The Dell A21328002 is a 2GB DDR3 Unbuffered DIMM (UDIMM) memory module, operating at a speed of 1333MHz. This module is designed for standard desktop computers and entry-level servers that are compatible with unbuffered memory configurations. UDIMMs are characterized by their direct signal path to the memory chips, which simplifies the memory architecture but limits the total memory capacity that can be installed compared to Registered DIMMs (RDIMMs). This module features a 2Rx8 configuration, indicating it is dual-ranked with an x8 data width per DRAM chip. Dual-rank modules can sometimes offer performance advantages by allowing the memory controller to access different ranks independently, potentially improving efficiency. The CAS Latency (CL) is rated at 9 clock cycles, which is a standard latency for DDR3 memory at this speed, defining the delay between the memory controller issuing a read command and the data becoming available. With a capacity of 2GB, the A21328002 is suitable for systems with moderate memory requirements or for upgrading older machines. It is important to note that UDIMMs typically do not support ECC (Error-Correcting Code) functionality, making them less suitable for mission-critical applications where data integrity is paramount. This module provides a cost-effective solution for general computing tasks, office productivity, and multitasking.
