Crucial Technology 114235 - 1GB DDR2 PC2-6400 Memory Module 240-Pin DIMM

When you buy Crucial memory you're buying directly from the largest DRAM manufacturer in America and one of the top three in the world. Crucial Technology is a division of Micron. We have more than 20 years of industry experience most efficient DRAM manufacturer and many of the world's leading computer manufacturers use our memory. Crucial brings that same high-quality memory directly to you the end consumer.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. A DDR2 SDRAM DIMM will not fit into a standard SDRAM DIMM socket or a DDR DIMM socket. The number of black components on a 240-pin DIMM can vary but it always has 120 pins on the front and 120 pins on the back for a total of 240. 240-pin DIMMs are approximately 5.25 inches long and 1.18 inches high though the heights can vary. While 240-pin DDR2 DIMMs 184-pin DDR DIMMs and 168-pin DIMMs are approximately the same size 240-pin DIMMs and 184-pin DIMMs have only one notch within the row of pins. The notch in a 240-pin DDR2 DIMM is closer toward the center of the module. Ballistix and Ballistix Tracer 240-pin DIMMs Our high-performance Ballistix 240-pin DIMMs come in DDR2 PC2-5300 SDRAM DDR2 PC2-6400 SDRAM and DDR2 PC2-8000 SDRAM. The Ballistix Tracer illuminated activity-indicating high-performance 240-pin DIMM comes in SDRAM DDR2 PC2-6400 SDRAM and DDR2 PC2-8000 SDRAM Ballistix 240-pin DIMM Approximately 5.25 in. by 1.18 in. (133.35 mm by 30 mm) Ballistix Tracer 240-pin DIMM Approximately 5.25 in. by 1.18 in. (133.35 mm by 30 mm)
