How to Install External RAM
Every motherboard has a maximum amount of memory it can support. You can install the maximum amount by filling up all the motherboard’s memory banks (sockets) with modules of the right type. If you’re ready to install your new RAM upgrade, follow these steps to install a typical DDR/DDR2/DDR3 module:
Cover your work surface with several sheets of newspaper (to protect your case).
Power down your PC, unplug it from its power source, and place it on top of the newspaper.
Remove the PC’s case.
Most PC cases are held on with two or three screws; just remove the screws and slide the case off. (Don’t forget to stash those screws in a safe place.) Other cases are hinged, often with a lock. If you’re unsure how to remove your PC’s case, check the manual that accompanied your computer.
Touch the metal chassis of your case to dissipate any static electricity on your body.
An electrical charge can send your new RAM modules to Frisco — permanently.
Locate the DIMM slots.
Check the motherboard manual, which should have a schematic diagram that helps you locate the slots. Typically, the RAM modules are found close to the CPU, in the center or in one corner of the motherboard.
Turn your PC’s chassis so that the DIMM slots are facing you and make sure that the two levers on the side of the socket are extended.
Note that the notches cut into the connectors on the bottom of the memory module match the spacers in the sockets themselves, so you can’t install your modules the wrong way. (Smart thinking there.)
Align the connector on the bottom of the module with the socket and push down with light pressure to seat the module.
While you push down, the levers on each side of the socket should move toward the center, until they click in place.
After you correctly install the module, the two levers should be tightly flush against the sides of the memory module to hold it securely.
Slide the cover back on your PC and secure it.
Move your PC back to its place of honor and plug it in.
Restart your computer and prepare to enjoy a faster PC!
