Applications

PC2100 DDR SDRAM (DDR1) was the standard desktop memory type for systems built in the early-to-mid 2000s, commonly paired with Intel Pentium 4, Celeron, and AMD Athlon XP platforms on chipsets such as Intel 845, 850, Via KT266, and AMD 760. The 184-pin unbuffered DIMM format was the dominant desktop memory form factor of that generation, replacing SDRAM and preceding DDR2. These modules are still sought by users maintaining legacy Pentium 4 and Athlon XP workstations, vintage computer collectors, and IT shops supporting older institutional hardware. At 256MB, this module represents a typical single-stick upgrade or replacement part for early-2000s desktop PCs. Samsung was among the most widely used and trusted DRAM manufacturers of this era, and Samsung-labeled DIMMs from this period are well-regarded for stability and compatibility.
