Product Description
The IBM 4454-7028 memory kit delivers a significant 8GB of RAM, packaged as four 2GB Micro-DIMM modules. This kit is specifically engineered for IBM systems that utilize the ultra-compact Micro-DIMM form factor, which is essential for ultra-portable laptops and other space-constrained computing devices. The DDR-266MHz speed, while dated by modern standards, was appropriate for the systems designed to use this specialized memory, providing adequate bandwidth for their intended applications. Each 2GB module in this kit is configured as 2Rx8, indicating a dual-rank design with an x8 data width per rank. This configuration can enhance performance in certain server or workstation environments by allowing the memory controller to access different ranks concurrently. The CAS latency (CL) of 2.5 clock cycles is a key timing parameter that defines the responsiveness of the memory modules, balancing speed with operational stability for DDR-266 technology. This 8GB Micro-DIMM kit represents a substantial memory upgrade for compatible IBM systems, enabling them to handle more demanding tasks, run more applications simultaneously, or improve overall system responsiveness. It is crucial for users to confirm system compatibility with the 4454-7028 part number or its specifications to ensure proper function and avoid potential issues. This kit is ideal for extending the life or enhancing the capabilities of specific IBM portable computing platforms.
