Description

The IBM 4490-9117 memory kit provides a total of 4GB of DDR-266MHz RAM, packaged as four 1GB Micro-DIMM modules. This specialized Micro-DIMM form factor is significantly smaller than standard DIMMs and SO-DIMMs, making it suitable for ultra-portable laptops, subnotebooks, and other compact computing devices where space is a critical constraint. The DDR-266MHz speed is characteristic of the systems for which this memory is intended, offering sufficient bandwidth for their operational requirements. Each 1GB module in this kit is configured as 1Rx8, meaning it is single-ranked with an x8 data width. This configuration is typical for memory modules of this capacity and speed, providing a standard interface for the system's memory controller. The CAS latency (CL) of 2.5 clock cycles is a key timing parameter that affects the memory's responsiveness, defining the delay between a read command and data availability. This 4GB Micro-DIMM kit is designed for compatibility with specific IBM systems that require this unique memory type. Users must verify that their device supports the 4490-9117 part number or its exact specifications to ensure proper installation and operation. It serves as an effective upgrade or replacement option for extending the usability and performance of these specialized IBM portable computing platforms.
