Product Description
The IBM 40P9489 memory module is a 512MB component designed to upgrade or expand the Random Access Memory (RAM) in compatible IBM systems. It operates at a speed of DDR-266MHz, offering a balance of performance and compatibility for a range of enterprise applications and server workloads. The module utilizes Unbuffered DIMM (UDIMM) technology, which is common in many server and workstation environments, providing a direct pathway for data to the memory controller. This specific module features a 2Rx8 configuration, indicating two ranks of memory chips, each with eight chips per rank. This organization can influence performance and how the memory controller addresses the module. Furthermore, it boasts a CAS Latency (CL) of 2.5, which refers to the number of clock cycles required for the memory module to respond to a column address command. Lower latency generally translates to faster data access. Designed with reliability and performance in mind, the 40P9489 is suitable for enhancing the capabilities of IBM servers and workstations. By increasing the available memory, users can expect improved system responsiveness, better handling of concurrent tasks, and the ability to run more demanding software applications. This module is a key component for optimizing system performance and ensuring smooth operation in business-critical environments.
