Description
This IBM 4453-9406 memory kit provides a total of 4GB of DDR SDRAM, distributed across four individual 1GB modules. Each module operates at a speed of 266MHz, commonly referred to as PC2100, and features a CAS Latency (CL) of 2.5. This specific timing is crucial for ensuring compatibility and optimal performance within the systems it is designed for. The key distinguishing feature of this memory is its Micro-DIMM form factor. Micro-DIMMs are significantly smaller than standard DIMMs and SO-DIMMs, making them suitable for compact computing devices such as certain laptops, small form factor PCs, or specialized industrial equipment where space is at a premium. The 1Rx8 configuration indicates that each memory chip is organized as a single rank with 8 data lines, which is a standard configuration for DDR memory. This kit is intended as a memory upgrade or replacement for IBM systems that specifically require DDR-266MHz Micro-DIMMs. Users should verify system compatibility before purchase to ensure the modules will function correctly. Proper installation is essential for system stability and performance, and it is recommended to follow the manufacturer's guidelines for memory upgrades.
