adding memory
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.
ADDR DIMM
To determine which type of memory module your PC
uses, and for specific memory module information
and specifications, go to the Web site listed in your
Warranty and Support Guide and click the
Support link.
WARNING: Using the wrong type of
memory module could damage the

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.
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.
removing an add-in card
1 Complete the procedures to prepare the PC and to
remove the side panel. See “opening and closing
the pc“ on page 1.
