Product Description
This IBM 1GB memory module, identified by SKU 7028-4451, is a component designed to upgrade or replace memory in specific IBM systems. It is a DDR memory module operating at a frequency of 266MHz, which was a common speed for systems of its era. The module features a CAS Latency (CL) of 2.5, indicating the number of clock cycles it takes for the memory to respond to a request, providing a balance between speed and stability for general computing tasks. The module utilizes the Micro-DIMM form factor, a compact memory module type often found in IBM's smaller footprint servers, workstations, or specialized devices. The 2Rx8 designation signifies that the module is dual-ranked, with eight memory chips per rank. This configuration allows the memory controller to access different ranks of memory independently, potentially improving performance by increasing the effective bandwidth and reducing wait times, especially in systems designed to take advantage of this feature. Adding or replacing memory with this 1GB module can help improve system responsiveness, particularly in environments where the existing memory capacity is a bottleneck. It is intended for IBM hardware that specifically requires DDR 266MHz Micro-DIMM memory with a 2Rx8 rank configuration, ensuring compatibility and contributing to the overall operational efficiency of the system.
