How to Upgrade the Memory in Linux

Sticks of RAM come in many varieties. Make sure you've got the right type.

Upgrading a Linux computer's memory is done exactly the same way as upgrading any other computer's memory--by installing more RAM. RAM, or random access memory, is a type of short-term, high-speed memory your computer uses to store data for programs you are running. The more of RAM you have, the less time your computer spends ferrying data between the hard drive and RAM. Installing RAM is a fairly simple process, if you're willing to open up your computer and tinker with its insides.

Things You'll Need

• RAM

Instructions

1. Turn off your computer and unplug its power cable.

2. Open your computer's casing, but don't touch any components yet.

3. Ground yourself to avoid damaging computer components with static electricity. You can ground yourself by touching a grounded metal object, like the screw holding the faceplace of a power outlet.

4. 

   A stick of RAM.

   Locate where your RAM is installed. A stick of RAM is a long, flat circuit board with small, black rectangles embedded in it.

5. Remove old sticks of RAM from their slots to free up enough empty slots for your new RAM. Press down on the clips on either side of a stick of RAM to free it from its socket, then pull upward to remove it. If it seems stuck, rock it gently back and forth. If you have enough free slots without removing any of the old RAM, skip this step.

6. Insert the flat, extended edge of the new stick of RAM into the socket. Sticks of RAM have notches along the contact edge that only fit into the socket one way. Don't force the RAM into place or you may damage the socket.

7. Press down on the top edge of the stick of RAM until the clips on either side of the socket snap into place. Your memory upgrade is now installed.

8. Replace the computer casing, plug the computer back in and turn it on. The computer automatically detects the new RAM during its boot-up process.

Tips & Warnings

• There are many types of RAM available, and motherboards are designed to accept only one type of RAM. Make sure you buy the right type of RAM for your computer. Check the Resources section for help determining what type of RAM you need.
