240-pin DIMM

*
Approximately 5.25″ X 1.18″

A dual inline memory module (DIMM) consists of a variety of memory components attached to a published circuit board. The yellow pins top top the bottom of the DIMM administer a connection in between the module and a socket on a published circuit board. The pins ~ above the former and ago of a DIMM room not associated to each other.

DDR2 SDRAM use 240-pin DIMM sockets for desktop computers. Every 240-pin DIMM offers a 64-bit data path (72-bit for ECC or registered modules), for this reason they are installed one in ~ a time in 64-bit systems. DDR2 chipsets space expected to assistance dual-channel memory, giving a 128-bit data path.

240-pin DIMMs are accessible in DDR2 or DDR3 SDRAM.

Memory modules (Unbuffered, Registered, tiny Outline DIMMs) have a unique “key” or notch in your connector. These tricks must align through a vital in the storage socket to permit the module to it is in inserted. All DDR3 and DDR2 module species are keyed differently.

To use DDR2 memory, your device motherboard must have 240-pin DIMM slots and a DDR2-enabled chipset. A DDR2 SDRAM DIMM will not fit right into a typical SDRAM DIMM socket or a DDR DIMM socket. DDR2 modules use a 1.8V power supply, providing a huge power saving over the 2.5V DDR modules.

To usage DDR3 memory, your system motherboard must have 240-pin DIMM slots and also a DDR3-enabled chipset. A DDR3 SDRAM DIMM will certainly not fit into a typical SDRAM DIMM socket, DDR DIMM socket or DDR2 socket. DDR2 modules use a 1.5V strength supply, providing a big power saving over the 2.5V DDR modules or 1.8V DDR2 modules. DDR3 is the next generation of twin Data rate (DDR) Synchronous Dynamic Random access Memory (SDRAM). The is an evolution of DDR and DDR2 memory technology that delivers higher speeds, lower power consumption and also heat dissipation.

The number of components on a 240-pin DIMM may vary, yet they always have 120 pins top top the front and also 120 pins ~ above the back. 240-pin DIMMs are about 5.25″ long and 1.18″ high, despite the heights may vary. While 240-pin DDR2 DIMMs, 184-pin DDR DIMMs and also 168-pin DIMMs are roughly the very 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 slightly more toward the facility of the module.

Approximately 2.625” x 1”

The SODIMM is a smaller sized version that the DIMM. Lock are mostly used in Laptop although they are used in some others choose the initial tray-loading iMac computer. They have actually a notch in the bottom that the circuit board, i beg your pardon is offset from the mi dd le, which makes inserting it much easier to line up.

144-pin SODIMMs are generally found in laptop computers. Every 144-pin SODIMM offers a 64-bit data path, therefore they are mounted alone in 64-bit systems. 144-pin SODIMMs are accessible in FPM, EDO, PC66, PC100 and PC133.

The number of black chips ~ above a 144-pin SODIMM might vary, but they always have 72 pins top top the front and also 72 pins top top the earlier for a total of 144. 144-pin SODIMMs are about 2.625″ long and also 1″ high, and also the heights may vary. They have one small notch within the row of pins follow me the bottom of the module.

Approximately 2.625” x 1”

The SODIMM is a smaller sized version of the DIMM. Lock are mainly used in Laptop systems. They have a notch in the bottom of the circuit board, i beg your pardon is offset from the mi dd le, which renders inserting it much easier to line up.

200-pin SODIMMs are provided to carry out DDR SDRAM storage for laptop computers. Each 200-pin SODIMM offers a 64-bit data path, therefore they are installed alone in 64-bit systems. 200-pin SODIMMs are available in PC2100 and PC2700.

The number of black chips ~ above a 200-pin SODIMM might vary, however they constantly have 100 pins top top the front and also 100 pins top top the ago for a complete of 200. 200-pin SODIMMs are about 2.625″ long and also 1″ high, and also the heights might vary.

204-pin SODIMM

*

Approximately 2.6″ X 1.75″ (66 mm X 44.45 mm)

204-pin tiny outline double inline memory modules (SODIMMs) are the type factor supplied to carry out DDR3 memory modules for notebook computers and other small type factor computing platforms. 204-pin SODIMMs are currently obtainable in PC3-8500 (DDR3 1066MHz) speeds.

To usage DDR3 memory, your system must have actually both a 204-pin SODIMM slot and also a chipset the supports DDR3 memory. A DDR3 SODIMM will certainly not fit into DDR2 or DDR storage sockets.

SODIMMs space smaller and also thinner than consistent DIMMs, and also the 204-pin SODIMM PCBs are constantly ~2.6 inches long and are usually approximately 1.75 inches high (though the heights deserve to vary slightly). Lock consist the a number of memory materials (usually black) that room attached to a printed circuit board (usually green). The variety of memory components on a 204-pin SODIMM’s published circuit plank (PCB) deserve to vary, yet the PCB will constantly have 102 pins ~ above the front and also the ago both, for a full of 204 pins. The yellow pins on the bottom of the SODIMM provide the connection in between the memory module and also the memory socket.
