Installing a Memory Module
1Choose the size of the memory module and configuration as shown
in the following table. Memory modules can vary in size and speed
between sockets. The minimum memory size is 128 MB. The
maximum memory size is 1 GB. The BIOS automatically detects the
type, size and speed of the memory modules.
2If necessary, remove the memory module you wish to replace (see
“Removing a Memory Module” on page 35).
3Remove the new memory module(s) from its anti-static package.
Hold the memory module only by its edges to prevent static-
electricity damage.
4Remove the side panel (see “Removing the Side Panel” on page 26).
5Remove the power supply (see “Removing the Power Supply” on
page48).
6Remove the screw that secures the AGP add-in card to the chassis.
7Press down on the handle at the edge of the AGP slot.
!Before opening the system unit, save and close all open files, exit all open
applications, turn off the power to all attached peripheral devices, shut
down the computer, and unplug the power cord.
