• Turn off the computer and touch the metal casing.
• Locate the RAM modules. Find the empty one you plan to replace, or remove the RAM module you will replace.
• Line up the notches of the new RAM module and apply firm pressure to attach.
• Once you’re sure the RAM module is snugly in place, close the latch at either end. If you have clips, they should snap back in place.
• Reconnect all the cables, but leave the casing open until you’re sure everything is working right.
• Turn your computer back on. If the machine starts to beep, the memory is either incompatible or not in correctly, says Ritchie. If you’ve installed everything correctly, the system will detect the new RAM.
• Check the system properties to see how much RAM you now have. If you replaced a 128 MB with a 512 MB module, then you should have 512 minus 128 equals 384 MB more RAM than you did previously. If you added the RAM but didn’t remove any, then you’d have 512 MB more RAM.
• Try one of your programs that wasn’t working up to speed. If it still isn’t working, unplug everything again and get back into the computer to check that the RAM modules are firmly secured.

Quick facts about RAM

RAM = random access memory. According to Microsoft Encarta, it is the primary working memory in a computer used for the temporary storage of programs and data and in which the data can be accessed directly and modified.

Contact the manufacturer or use an online memory advisor, such as the one from Crucial Technology or Kingston Technology, that will tell you which products work with your system.

To find out what kind of module you will need, you can also open up your computer.

• First, turn off the computer, but leave it plugged in, because then it’s automatically grounded, explains Ritchie. (Computers that should not remain plugged in will be clearly marked.)
• Place the computer on a clean workspace and remove the cover carefully (you may need to use a screwdriver).
• Touch the case to ground yourself. “If you’ve got a static charge then you won’t once you’ve touched the case,” says Ritchie. (Although some manuals recommend anti-static wrist straps, Ritchie says that this is not necessary for home users.)
• Locate the RAM modules, which are green with black tubes, on the motherboard.
• Now determine the type of module you have. “It’s all in the look of the slot,” explains Ritchie.
  • RDRAM is paired up (you have to put in two at a time) and has metal casing on one side;
  • DDR SDRAM is the most popular and looks like regular RAM, but has one notch;
  • SDRAM (which is being phased out) has two notches.
• Also note your RAM speed, which is usually written on the side of the existing chip (either 266 or 333).
• If you don’t have a free slot, remove one of the memory cards to check the number of notches on it. You’ll be replacing the smaller of the two RAM modules.

To see how much RAM is in your PC, go to the Start menu, click Settings, and then click Control Panel. Click System and then select the General tab. At the bottom of the page you should see the amount of RAM.

Most games will specify the minimum amount of RAM you need to install them and play. For example, Harry Potter And The Prisoner of Azkaban requires 256 MB. This amount includes RAM that the computer needs to do its own background work as well as to run the game.

Dale Mater, tech lead at CompTech Care, says that the amount of RAM you need depends on the operating system you are using. For Windows 98, 128 MB to 256 MB is more than enough. For Windows XP, “the more the merrier—depending on what you’re doing,” he says. If you’re just surfing the Internet and writing letters, you need 256 MB to 512 MB. “If you’re gaming, the sky’s the limit,” says Dale, which means anywhere from 512 MB to 1 GB RAM (extreme gamers will need even more). You’ll also need more RAM if you’re using a lot of applications at the same time, such as desktop publishing and video rendering.

RAM modules can be purchased in 128 MB, 256 MB, and 512 MB sizes. To get more memory for your computer, call the experts at CompTech Care at 800-332-6153 or visit our website.
