Product Description
The IBM 9406-4453 memory kit provides a significant upgrade for compatible IBM systems, offering a total of 4GB of RAM distributed across four 1GB Micro-DIMM modules. This configuration is designed to boost system performance, enabling smoother multitasking and the ability to run more demanding applications. The DDR SDRAM technology ensures efficient data transfer, while the PC2100 rating signifies a clock speed of 266MHz, which was standard for many systems of its era. The 1Rx8 designation indicates that each module is single-ranked with eight memory chips per rank, a common configuration for performance and compatibility. The CAS Latency of CL2.5 specifies the number of clock cycles required for the memory controller to access a specific column in a row once the row has been activated. A lower CAS latency generally translates to faster response times, and CL2.5 provides a good balance for the DDR-266MHz speed. This memory kit utilizes the Micro-DIMM form factor, which is smaller than standard DIMMs and is typically found in specific compact or specialized IBM systems. It is crucial to verify system compatibility before installation, as Micro-DIMMs are not interchangeable with other DIMM types. Upgrading memory with this kit can lead to noticeable improvements in application load times, system responsiveness, and overall computing experience for supported IBM hardware.
