How to Install RAM

Has your computer started to feel a little sluggish? Maybe it’s not performing like it used to, or can’t keep up with the latest software? Upgrading your RAM (Random Access Memory) is one of the simplest and cheapest ways to quickly improve your computer’s performance. RAM can be upgraded on virtually any computer, and only takes a screwdriver and a few minutes. Read on after the jump to learn how.

Find out what type of RAM is required for your desktop computer. RAM comes in a variety of models and speeds. The type of RAM you can get is dependent on your computer’s motherboard. Check your motherboard or computer’s documentation, or check the manufacturer’s website for the RAM specifications that are compatible with your hardware.

• RAM is available as DDR (double data rate), DDR2, and DDR3. Most newer computers use DDR2 or 3. You must get the type that matches what your motherboard supports
• RAM is identified by two different speed numbers: the PC/PC2/PC3 number and the MHz speed. Make sure that both match your motherboard’s specifications.
• The PC number (ex. PC3 12800) refers to the maximum bandwidth (ex. 12800 = 12.8 GB maximum bandwidth).
• The speed of the RAM is signified by the number after the DDR specification (ex. DDR3 1600 = 1600 MHz).

Check how many sockets you have for RAM. Your motherboard has a limit to the number of RAM sticks you can install. Some motherboards support only two, while others support four, six, or even more.

• Most motherboards have a limit to the amount of memory that they support, regardless of the number of slots.
• iMacs use notebook memory, so refer to the next section for instructions on how to install it.

Make your purchase. Once you’ve decided on a manufacturer, you can pick your RAM. When buying desktop RAM, be sure to buy SDRAM. RAM is best installed in matching pairs, so you may need to buy two or four sticks to get the amount of RAM that you want.

• For example, to get 8 GB or RAM you might install two 4 GB sticks or four 2 GB sticks. Make sure that what you get can fit in your motherboard. Try to install RAM in pairs such a if you want 4 GB, then install 2 GB and 2GB. Never install them in different pairs such as one is 2 GB and the other one is 1 GB etc., it might decrease your RAM performance.
• All of the RAM you have installed should have matching speed and bandwidth. If they don’t match, your system will be clocked down to the slowest stick, reducing performance.
• Double check what your motherboard supports before committing to the purchase.

Shut down the computer. Unplug the computer and any peripherals connected to the computer, such monitors, keyboards, and mice.

Open your computer case. Lay your computer tower on its side, so that you can access the motherboard when the side panel is removed. You may need a Phillips-head screwdriver to remove the panel, or you may be able to unscrew it by hand.

Discharge any static. Ensure that you do not have static build-up on your body. Static can damage computer parts, and can be imperceptible to a human. Ground yourself before starting, or use an antistatic wrist strap.

• You can ground yourself by touching a metal part on your computer case while it is plugged in but turned off.
• You can ground yourself by touching any plugged in appliance that has a grounded wire, or by touching a water tap.
• Don’t stand on carpet while working on the interior of the computer.

Locate your RAM sockets. Most motherboards have 2 or 4 RAM slots. RAM sockets are typically located near the CPU, though their location may vary depending on the manufacturer or model. Refer to your motherboard’s layout diagram in your documentation if you are having difficulty locating he sockets.

Remove old RAM (if upgrading). If you are replacing old RAM, remove it by releasing the clamps on each side of the socket. The RAM will be released from the socket, and you’ll be able to lift it straight out of the motherboard with little to no effort.

 Insert the RAM into the RAM slot. Line up the notch in the stick of RAM to the break in the slot. Set the stick into the slot and then apply equal pressure onto the stick until the clamps on the side click and lock the RAM in. You may have to apply a fair amount of pressure, but never force it in.

• Make sure matching pairs are inserted into their matching sockets. Most are labeled on the board or by color, though you may need to refer to your motherboard layout diagram. Make sure that they are facing the same way.
• Repeat the process for each stick of RAM you want to install.

1. Close up the computer. Once you’ve finished inserting your RAM sticks, you can put the panel back on and screw it back in. Avoid running your computer while the panel is off, as this will actually reduce the cooling power of your fans. Plug your peripherals and monitor back in.
2. 
   
   Power on the computer. Your computer should start normally. If your computer displays the self-test during the startup, then you can verify that the RAM has been installed correctly. If not, you can verify that the RAM was installed once Windows starts.
3. Check the RAM in Windows. Press The Windows key + Pause/Break to open the System Properties. You can also click the Start menu, right click on Computer/My Computer and click Properties. Your RAM will be listed in the System section or at the bottom of the window.
   

   • Operating systems calculate memory differently and some computers dedicate a certain amount of RAM to specific functions (e.g., video), decreasing the amount available. For example, you may have purchased 1 gigabyte of RAM. The operating system may only display 0.99 gigabytes.
