Product Description
The HP 0733A1 is a 4GB DDR3 Unbuffered DIMM (UDIMM) memory module, suitable for a wide range of desktop computers, workstations, and entry-level servers. Unlike Registered DIMMs (RDIMMs), UDIMMs do not have a register chip between the memory controller and the DRAM chips, which can sometimes offer slightly lower latency but generally less scalability and error correction capability for very large memory configurations. This module operates at a frequency of 1333MHz, providing adequate bandwidth for everyday computing tasks and moderate workloads. The CAS Latency (CL) is rated at 9, indicating a reasonable response time for memory operations. It supports ECC (Error-Correcting Code) functionality, which allows for the detection and correction of single-bit errors, enhancing data reliability over non-ECC memory, though it is less robust than the ECC found in RDIMMs. The module is a dual-rank (2R) design, meaning it has two sets of memory chips on the module, which can improve performance in certain system architectures. It operates at standard DDR3 voltage, typically 1.5V. The HP part number 0733A1 signifies its origin and adherence to HP's quality standards, making it a reliable choice for systems requiring compatible DDR3 memory upgrades.
