Ensure that the RAM you purchase to install matches the configuration of the existing RAM that you already have installed on your PC. You can verify this information at your PC manufacturer's website.
Shut down your PC, and disconnect any peripheral devices you may have, such as the monitor, mouse, keyboard, printer, etc. Unplug it from its power source. Unscrew the computer cover and set it aside.
Ground yourself before you handle any of the inner components. You can do this using an antistatic band or other professional grounding equipment. Alternatively, touch on the metal of the computer's chassis.
Locate the empty RAM sockets on your motherboard. Release the securing clips on either side of the RAM socket.
Pick up your RAM module by its ends, taking care not to touch the chips or pins. Line up its notched edge with the tab along the bottom of the RAM socket.
Slide it into the slot using slight pressure to press it firmly in till you hear it click into place. Gently tug on the module so as to ensure that it is snugly locked in position. The securing clips on either side will snap back to hold it in place.
Screw the computer case back in place. Reconnect your monitor, mouse and keyboard. Plug it back in and reboot your system. Your system should recognize the new memory automatically, and run faster and more efficiently.
Quick Tip: Your system will better adjust to an upgrade if you install additional RAM in pairs.
