A Dimm (Dual Inline Memory
Modules) consists of a number of memory components attached to a PCB (printed
circuit board). The gold pins on the bottom of the Dimm provide two lines of
communication between the module and the system.
168 Pin DIMMs are
commonly found in Pentium and Athlon based systems and can be installed singly
in 64-bit systems. 168-pin DIMMs are available in EDO, FPM and SDRAM (66Mhz,
100Mhz and 133Mhz). The number of black components on a 168 Pin Dimm may vary
but they always have two cutouts along the row of gold pins on the bottom of
the module.
Module Details:
168 Pin Dimm Dimensions: 5.375" x 1.375" approx
Manufacturer: Top tier manufacturers including Samsung, Nec & Hynix
Number of Contacts: 84 Pins Front & 84 Pins Back

The following information is provided to assist with the installation of 72 Pin Simms, 168 Pin Dimms, 184 Pin Dimms/Rimms and 240 Pin Dimms.
General Precautions
1.
Turn off the computer and disconnect the AC power cord.
2.
Remove the computer
cover following the instructions located in your system owners manual.
3.
Before installing your
memory, discharge any static electricity by grounding yourself to a metal object, such as the casing on your computer.
4.
Locate the area where the memory is to be installed and remove any peripherals that may be obstructing access to the memory sockets.
5.
All modules must only be handled by their edges and should not be handled by the chips themselves.
6.
Remove any existing memory if necessary to install the new memory products
7.
72 Pin memory is generally installed in pairs but 168 Pin Dimms can normally be installed one at a
time. Please refer to your owners manual for specific information.
72 Pin Simm Memory Installation Guidelines
1.
Align the metal connectors of the memory
module with the metal connectors of the simm socket on the motherboard. Be sure
that the simm is aligned properly and that all pins line up correctly. If the
simm does not fit, turn it around as simms are keyed and will only fit in one
way round. 168 Pin Dimms have two cutouts along the row of pins and 184/240 Pin Dimms
have only one cutout.
2.
Insert the module at a 45 degree angle and
carefully grasp the two ends of the module and gently snap into place into the
upright position.
3.
Check to make sure that both retaining
posts have locked onto the module and are holding it securely in place.
4.
Replace the computer cover and reattach
cables and peripherals..
5.
Update the computers memory configuration if required as outlined in the computer users manual
Align the metal connectors of the memory module with the metal connectors of the dimm socket on the motherboard. Be sure
that the dimm is aligned properly and that all pins line up correctly. If the dimm does not fit, turn it around as dimms are keyed and will only fit in one way round.
2.
Make sure that the Dimm retaining clips are open and firmly press the Dimm down into the socket and lock the retaining clips in place.
3.
Replace the computer cover and reattached cables and peripherals..
4.
Update the computers memory configuration if required as outlined in the computer users manual
The following information is provided to assist with the installation of 72 Pin SoDimms, 144 Pin SoDimms and 200 Pin SoDimms. Specific memory upgrade information particular to your model of
computer will be detailed in your users manual.

SoDimm Memory Installation Guidelines
1.
If the SoDimm is being installed into a
notebook or hand-held computer that has a battery installed, then ensure that
the battery is removed before beginning installation.
2.
72 Pin SoDimms have a small cutout on the
bottom of the module next to the pins. This ensures that the modules can only
be installed one way round. 144 Pin and 200 Pin SoDimms have a cutout along the pins which
again only allows the module to be inserted one way round.
3.
Insert the module at a 30 degree angle and push the module firmly but gently into the slot until the security latches on the sockets have locked into place on each side of the module.
4.
Replace the computer cover and reattach cables and peripherals..
5.
