Compare Crucial 2GB MB DDR2 RAM (CT25664AA800) to Corsair 16gb MB DDR2 RAM (CMSO16GX3M2A1333C9)

A dual inline memory module DIMM consists of a number of memory components usually black that are attached to a printed circuit board usually green. The gold pins on the bottom of the DIMM provide a connection between the module and a socket on a larger printed circuit board. The pins on the front and back of a DIMM are not connected to each other. 240-pin DIMMs are used to provide DDR2 SDRAM memory for desktop computers. DDR2 is a leading-edge generation of memory with an improved architecture that allows it to transmit data very fast. Each 240-pin DIMM provides a 64-bit data path 72-bit for ECC or registered or Fully Buffered modules. The Ballistix and Ballistix Tracer high-performance memory do not come in 72-bit or registered modules. Standard DDR2 240-pin DIMMs are available in DDR2 PC2-3200 SDRAM, DDR2 PC2-4200 SDRAM, DDR2 PC2-5300 SDRAM, and PC2-6400 SDRAM. To use DDR2 memory, your system motherboard must have 240-pin DIMM slots and a DDR2-enabled chipset. Less
