6. System Expansion
6-1. Opening the computer case
Always consult with your service representatives before opening the computer
case.
Follow the guidelines below when opening the case.
ã Quit all running programs.
ã Turn off the computer and monitor, and unplug and remove the power cords.
ã Keep magnetic objects such as screw driver away from the parts inside the computer.
ã Open the computer case in a safe, clean area.
ã The static electricity can damage the parts inside the computer. Touch a bare,
unpainted metal part of the computer for 2~3 seconds to remove the static electricity before opening the computer case.
ãAlways wear gloves to avoid injury when disassembling the computer.
Opening and closing the computer case
Remove 3 screws from the cover and
then push the cover as the direction of
the arrow.
Push the cover in the direction of
arrow as it aligns the groove of computer cover with body shown on the
picture and fasten 3 screws.
Make sure that there is no metallic object left inside the computer before closing the case.
There is the risk of electric shock or fire.

6-5. Increasing the memory
If you run out of memory while using the computer, you may want to increase the
amount of memory in your computer.
About memory
Your computer uses DDR(Double Data Rate) SDRAM DIMM(Dual In-Line Memory
Module) with 184 pins. Your computer supports Unbuffered DDR SDRAM DIMM of
256MB up to 512MB in size in each socket, and 2GB total.
Note
ã Windows 95, 98SE, ME supports memory up to 512MB total. Increasing the memory
beyond 512MB in these systems may cause errors while using the computer.
Before increasing the memory
ã Always wear gloves to avoid injury when disassembling the computer
ã Static electricity can damage memory modules be sure to minimize the static
electricity when replacing memory.
ã Make sure to replace the memory of the same type as the installed memory.
ã DIMM is different from SIMM in that it is configured for 64 bit operation; therefore, your computer can operate with only one DIMM installed.
Note
ã Use a 2.5V DDR SDRAM DIMM.(The shape of the memory may be different depending
on the model) DDR SDRAM enhances the rate of data transmission of the SDRAM and
looks different from SDRAM.
DDR
74
System Expansion
ã Your computer supports PC2700/3200 DDR memory.
ã Use Unbuffered DDR SDRAM DIMM only to increase the memory.
ã Dual channel mode operates when each identical memory is installed in the same color
of DIMM slot.

Supported memory type

PC2700/3200-DDR SDRAM 333/400MHz
Purchasing a memory
Check the type of memory installed in your computer and refer to the memory configuration chart before purchasing a memory.
Specification: PC2700/3200(184 pin DDR SDRAM DIMM)
Speed

Replacing the memory
The main board configuration, memory socket, and the shape of memory may be
different depending on the model.
Note
ⓞ Remove the screws on the real of
the computer, and open the com
puter case.
ã Before opening the case, turn off the
computer and peripheral devices, and
remove the power cords.
ⓟ Pull the latch on each side of a memory socket to release the memory.
Latch
Installing a memory
ⓞ Pull the latch on each side of a memory socket.
Note
ã For dual channel system, each mem
ory should be installed in independent
slot(1&3 slot or 2&4 slot) when using
DDR Memory
ⓟ Align the notch at the bottom of the
memory with a protrusion in the middle
of the socket, and then insert the
memory straight down.
It is recognized as a single channel if
there is a difference between dual
channel 1 and 3, 2 and 4.

Checking the size of the installed memory
The computer automatically recognizes the newly installed memory; therefore,
you do not need to change the system setup. Follow the instruction below to
check the size of the installed memory.
ⓞ Connect the power cord and other devices, and turn on the computer and monitor.
The following screen appears to inspect the status of the computer.
ⓟ If the following screen appears, press [Esc]. POST screen appears.
ⓠ If the following screen appears, press [Pause] key to pause the screen. Make
