Upgrading your computer
Certain components of your computer are upgradeable such as the
memory, the hard disk, the CPU and the expansion cards. You need to
observe the “Installation precautions” on page 49 when installing or
removing a computer component. However, for safety purposes, we do
not recommend that you perform these upgrades yourself. If you want
to replace or upgrade any of these components, contact your dealer or
a qualified service technician for assistance.
Note: The mainboard model shown in the following figures may
not be exactly the same with the one found in your computer.
Installing additional memory
The four 184-pin sockets on the mainboard support Double Data Rate
(DDR) Synchronous Dynamic Random Access Memory (SDRAM)-type
DIMMs. You may install 128-MB, 256-MB, 512-MB or 1-GB DIMMs for a
maximum memory capacity of 4 GB.
The DDR DIMMs should work under 2.5 volts. You can install PC2100/
DDR266, PC2700/DDR333, or PC3200/DDR400 modules in the DDR
DIMM sockets. Contact your dealer for qualified DIMM vendors.
Each DDR DIMM socket is independent from the other. This
independence allows you to install DDR DIMMs with different
capacities to form different configurations.
To remove a DDR DIMM
Note: The DDR DIMM has only one notch located on the center of
the module.
1 Remove the side panel (see page 51).
2 Locate the DDR DIMM socket on the mainboard.
