Product Description
The Apple 661-3466 is a 512MB DDR SDRAM memory module, specifically designed as an Unbuffered DIMM (UDIMM) for compatible Apple Macintosh computers. Operating at a speed of 400MHz, it corresponds to the PC-3200 standard, offering a good balance of performance for systems of its era. This module is ideal for users looking to upgrade the memory in older Apple systems to improve multitasking capabilities and overall system responsiveness for everyday computing tasks. The module features a 2Rx8 configuration, indicating two ranks of memory chips, each with eight data lines. This configuration is common for DDR memory and provides efficient data access. With a CAS Latency (CL) of 3, it offers relatively fast access times for its generation. As an unbuffered module, it directly interfaces with the memory controller without an intermediate buffer, which is typical for consumer-grade systems rather than high-end servers that require registered memory for greater stability at higher capacities. This Apple-specific part number, 661-3466, ensures compatibility with the intended Apple hardware. While it is a standard DDR memory module, its designation by Apple suggests it has met their specific testing and compatibility requirements. It is a suitable choice for extending the lifespan of older Apple machines by providing a modest but effective memory boost for applications and operating systems of the time.
