How to Add RAM

If you have an existing computer, one fast, easy, and cheap way to increase its speed (making games and other programs run faster) is by adding more RAM.

If you are looking to purchase a new computer, you may want to look for one that has a small amount of RAM. Computer manufacturers usually charge a premium on the RAM, so it is often cheaper to buy a computer and install more RAM yourself rather than buy a computer with the RAM pre-installed.

Difficulty: Easy

Instructions

Things You'll Need:

• Computer
• RAM modules
• screwdriver
• owner's manual

1. 
   Crucial System Scanner tool

   The biggest mistake people make when purchasing RAM for their computer is getting the wrong "size." One possible reason is there are lots of "sizes" to consider -- amount of memory, length, number of pins (and what configuration), speed, etc. For this reason, it is highly recommended that you use a system scanning tool to identify what RAM is compatible with your system. The one I personally use is the Crucial System Scanner tool (link in the resources section below). Another popular tool is Belarc Advisor which give information on your entire computer (not just RAM), but does not make a suggestion for upgrade like the Crucial program does.

2. 
   PNY

   Once you have determined the size and kind of RAM you need, it is time to purchase it. Another reason I like the Crucial tool is they will tell you information that is helpful when purchasing RAM like the maximum RAM your system can utilize or if your computer requires RAM to be installed in pairs (two modules). If you do have to install in pairs, it can also tell you if the modules need to be the same density.
   
   Even if you don't purchase from Crucial, the information can help you if you order online from another store (like TigerDirect) or a physical store (like Staples). Be sure to get a reliable brand (like Crucial, PNY, or Kingston to name a few).

3. 
   Understanding your computer's owner's manual.

   With your RAM modules in hand and your computer in front of you, it is now time to install the memory. Depending on the type and model of your computer, how you access the memory slots within your computer will vary greatly. Refer to your owner's manual for help.

4. 
   Adding laptop memory.

   In general, if you are adding memory to a laptop, you will make sure the laptop is turned off, then tun it over to access the bottom of the laptop. Many of the newer laptops have a compartment that allows access to the memory by removing the compartment cover--usually requiring a small screwdriver. Once the cover has been removed and depending on how many RAM modules you are replacing, you may be able to leave the current memory in place and just add the new ones to the empty slot(s). To aid in your addition of memory, you may want to remove the memory that is currently in the laptop as installation is identical, only in reverse.
   
   Many laptops have ram that slides in from the side, then presses down to secure (like the picture). Again, check your owner's manual for verification.

5. 
   Adding desktop memory.

   In general, if you are adding memory to a desktop computer, you will make sure the desktop computer is turned off, then remove the case to access the motherboard inside the desktop. Many of the newer desktop computers have thumbscrews that allows access to the memory slots on the motherboard; some models require a small screwdriver to remove the case. Once the cover has been removed and depending on how many RAM modules you are replacing, you may be able to leave the current memory in place and just add the new ones to the empty slot(s). To aid in your addition of memory, you may want to remove the memory that is currently in the desktop as installation is identical, only in reverse.
   
   Most desktop computers have ram that slides in from the top (like the picture). Again, check your owner's manual for verification. Some models require you to physically move the clips to secure the RAM modules; other models clip automatically as you insert the RAM module.

6. 
   This computer has 512 MB of memory installed (look above the hourglass).

   Once your RAM modules have been installed, put the computer back together by reinstalling the module cover on the laptop or the case on the desktop. Turn on your computer and verify the new memory is being used. (On PCs running Windows, this information can be found by right-clicking My Computer and selecting Properties.)

Tips & Warnings

• Always add the most RAM you can afford (up to the maximum capacity for your computer system) for best performance.
• Computers and their components are highly sensitive to any form of electricity--even static electricity. Be sure to ground yourself before working on or in your computer to protect its sensitive parts.
• Computer memory is rugged and fragile at the same time. If you cannot get your module to fit in the slot, first check to see that you have it lined up correctly. Most modules have notches to allow the memory to only be installed one way. If you have the notches lined up correctly and the clips open (if any), you may just need to press down harder (but not too hard) on the module to get it to install.
