Product Description
The IBM 12R8614 is a memory upgrade kit consisting of four 1GB DDR SDRAM modules, totaling 4GB of memory. These modules utilize the Micro-DIMM form factor, which is significantly smaller than standard DIMMs and is typically found in compact or specialized IBM systems such as certain ThinkPads or other portable devices where space is at a premium. The memory operates at a speed of 266MHz, corresponding to the PC2100 standard, offering a balance of performance and compatibility for supported systems. Each module in the kit is configured as 1Rx8, meaning it is single-ranked with eight memory chips per rank. This configuration is common for DDR memory and is suitable for a wide range of applications. The CAS Latency (CL) is rated at 2.5, which indicates the number of clock cycles required to access a particular column in a row. A CL of 2.5 is typical for DDR-266MHz memory and provides adequate responsiveness for general computing tasks. This kit is specifically designed to meet the memory requirements of compatible IBM systems that require Micro-DIMMs. Upgrading to this 4GB kit can significantly improve system performance by allowing for more applications to run simultaneously, handling larger datasets, and reducing reliance on slower storage for virtual memory. It's crucial to verify system compatibility before installation to ensure optimal performance and stability.
