Product Description
The Apple 661-3465 is a 256MB memory module, specifically a DDR SDRAM Unbuffered DIMM (UDIMM). This module is engineered to enhance the performance of compatible Apple computers by providing additional random-access memory. With a speed rating of 400MHz, it is designed to meet the requirements of systems that utilize DDR memory technology, offering a noticeable improvement in multitasking capabilities and application responsiveness. The module is configured as 1Rx8, indicating it is a single-rank module with eight memory chips per rank. This configuration is common for standard desktop and server memory. The CAS Latency (CL) is rated at CL3, which refers to the number of clock cycles it takes for the memory module to respond to a command. Lower CL values generally indicate faster response times. This specific part number, 661-3465, is crucial for ensuring compatibility with Apple hardware. It is intended for systems that support DDR 400MHz memory and UDIMM form factors. Upgrading or replacing memory with the correct specifications, like this 256MB module, can significantly improve the overall user experience and system stability for supported Apple devices.
