Applications

PC100 SDRAM was the standard desktop memory type from roughly 1998 through 2001, introduced alongside Intel's 440BX chipset and used widely in Pentium II, Pentium III, AMD K6-2, and AMD K6-III systems. Motherboards of that generation typically accepted 168-pin unbuffered DIMMs at 100MHz, and many required matching modules to maintain stability at the rated bus speed. Today, PC100 SDRAM is primarily sought for legacy system maintenance, restoration of vintage desktop builds, and retrocomputing projects — replacing failed sticks in period-correct machines or filling empty DIMM slots to reach a system's maximum supported RAM. The 128MB capacity was near the top end of practical single-module capacity for this generation, making it a useful upgrade piece for Slot 1 and Socket 370 platforms.
