Product Description
This Apple 661-2658 memory module is a 256MB Unbuffered DDR SDRAM DIMM, operating at a speed of 266MHz, which corresponds to the PC2100 standard. This type of memory was commonly used in older generations of Apple Macintosh computers, particularly those from the early to mid-2000s. As an Unbuffered DIMM (UDIMM), it directly connects to the memory controller without an intermediate register. This makes it suitable for desktop and consumer-grade systems where the number of memory modules is limited. The module is non-ECC, meaning it does not have error-correcting capabilities, which is typical for consumer-oriented memory of that era. The 256MB capacity is relatively small by modern standards but was sufficient for the operating systems and applications of its time. This module is a specific replacement part for compatible Apple systems, ensuring proper function and compatibility. It is essential to verify system compatibility before purchasing, as DDR memory is not backward or forward compatible with other DDR generations.
