Applications

DDR PC3200 was the mainstream desktop memory standard from roughly 2003 to 2006, used in systems built around Intel Pentium 4, Celeron D, and early Pentium D processors on i865/i875/i915 chipsets, as well as AMD Athlon 64 and Sempron platforms. Motherboards from that generation typically used dual-channel DDR configurations with 184-pin slots, and a 1GB module was a common upgrade for office and home desktop builds. Today this type of module is still sought after for maintaining, restoring, or expanding legacy systems from that era — including older workstations, small form-factor PCs, and industrial computers that remain in service.
