Product Description

This 4GB DDR3 DIMM module, identified by the HP part number VH638AA-RFB, is a key component for upgrading or expanding the memory capacity of compatible HP servers and workstations. It operates at a data transfer rate of 1333MHz, corresponding to a bandwidth of PC3-10600, which is essential for efficient multitasking and application performance in demanding computing environments. The module is specified as Non-ECC (Error-Correcting Code) and Unbuffered, making it suitable for systems that do not require advanced error detection and correction capabilities, often found in entry-level servers or high-performance workstations. The CL9 CAS Latency indicates the number of clock cycles required to access a particular column in a row, contributing to the overall responsiveness of the memory. As a Dual Rank module, it utilizes memory chips on both sides of the PCB, which can sometimes offer performance benefits in certain system configurations by allowing the memory controller to access data more efficiently. This specific module is designed to meet the rigorous standards of HP hardware, ensuring compatibility and reliable operation within supported HP systems.
