S26361-F3000-L514:1024MB 533MHz PC2-4200 DDR2 SDRAM Unbuffered ECC Memory Module

DIMM is a type of circuit board that holds memory chips. DIMMs have a 64-bit path because of the Pentium Processor requirements. Because of the new bit path, DIMMs can be installed one at a time, unlike SIMMs which on a Pentium would require two to be added. DDR SDRAM, is a next-generation SDRAM technology. It allows the memory chip to perform transactions on both the rising and falling edges of the clock cycle.
