Adding RAM to Your Computer
DIMM size of DDR memory called a SODIMM. You can usually go to
the website of your computer manufacturer, type in your model number,
and find the exact type of memory that will work with your hardware.
Alternatively, use Kingston’s Memory Search tool at http://tweaks
.com/633323 to find the kind of memory you need. I recommend
shopping around; buying directly from computer manufacturers is typically
more expensive.
Number of open RAM expansion slots —To add additional memory to
your computer, you need to consider the number of open RAM expansion
slots you have on your motherboard. Most computers have either two
or four slots and, depending on your manufacturer or whether you built
it yourself, you may be using up all the slots. If your slots are all in use,
don’t worry—you can still upgrade your RAM if you are not already at
the max your machine supports. Pieces of RAM usually come in
combinations of 256 MB, 512 MB, 1 GB, 2 GB, 4 GB, and now 8 GB of memory
per stick. Say you have two RAM slots and they are both currently filled
with 256 MB RAM chips; you can still buy two 512 MB chips to replace
them, which doubles the amount of RAM you have. Ideally, if you have
a lot of slots free it is a good idea to buy DDR memory in pairs so you
can take advantage of the dual-channel architecture. You will notice two
different colored DIMM slots on your motherboard if your system
supports dual channels.
Installing Your New RAM
After you have ordered or picked up your new RAM, it is really easy to install it
yourself. Keep in mind that opening your case may void your warranty. Having
fun yet? Follow these steps to pop in your new memory:
1. Unplug all the cables on the back of your computer, including the power
cable. Detach the battery if working on a laptop.
2. Use a Phillips screwdriver or push the case release button to remove your
case or memory hatch.
3. When you have access to your motherboard, locate the memory
expansion slots, as shown in Figure 16-1. Attach your antistatic wristband at
this time. Don’t have one? No big deal. Just touch any part of the metal
case frame with your hand to discharge yourself.
4. Removing any existing pieces of RAM is very simple. Push the plastic
or metal clips away from the sides of the stick of RAM. This will usually
cause the RAM to pop out.
