Your PC comes with random access memory (RAM),  
which temporarily stores data and instructions on your  
PC. The PC ships with one or more memory modules,  
but you can replace the existing memory module(s)  
with higher-capacity ones.  
The motherboard contains sockets for DDR DIMMs  
(double data rate dual in-line memory modules). The  
exact number of sockets and type of DDR memory  
module depends on which model PC you have.  
WARNING: Do not pull the memory  
module out of the socket. Use the  
retaining clips to eject the module.  
6 Lift the memory module from the memory socket.

motherboard.  
WARNING: Be careful of the sharp edges  
on the add-in card slot cover.  
removing or installing an  
add-in card  
An add-in card is a circuit board, such as a PCI or an  
AGP card that fits into a PC add-in card slot. Your PC  
contains several add-in card slots that can be used to  
add components to your PC. The PC component  
configurations vary by model.  
5 Remove the slot cover.  
Or  
Holding the card at each end, carefully rock it back  
and forth until the connectors pull free from the  
socket, and then remove the card. Be sure not to  
scrape the card against the other components.  
Store the old card in the anti-static packaging that  
contained your new card.  
WARNING: Do not overload the system  
by installing add-in cards that draw  
excessive current. The system is designed  
to provide 2 amps (average) of +5 V  
power for each board/card in the  
computer. The total +5 V current draw in  
a fully loaded system (one with all add-in  
card slots filled) must not exceed the total  
number of slots multiplied by 2 amps.  
A Phillips screwdriver is needed to remove, replace,  
or add an add-in card.  
Upgrading and Servicing Guide 7  
 
6 If you are not replacing the old add-in card with a  
new add-in card, close the open slot by inserting
