Product Description
The Apple 661-3680 is a 1GB memory module, specifically a DDR SDRAM Unbuffered DIMM (UDIMM). This module is designed to boost the performance of compatible Apple computers by increasing the available system memory. Operating at a speed of 400MHz, it aligns with the requirements of systems that utilize DDR memory, facilitating smoother multitasking and faster application loading times. This module is configured as 2Rx8, indicating it is a dual-rank module. Dual-rank modules can sometimes offer performance benefits in certain system architectures by allowing the memory controller to access different ranks of memory concurrently. The CAS Latency (CL) is set at CL3, representing the number of clock cycles required for the memory to respond to a request, contributing to its overall responsiveness. As with other Apple-specific components, the 661-3680 part number is critical for ensuring proper compatibility with the intended Apple hardware. It is suitable for systems that support DDR 400MHz memory and UDIMM form factors. Installing this 1GB module can provide a significant upgrade for users looking to improve the speed and efficiency of their supported Apple devices.
