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.

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
128MB up to 1024MB in size in each socket, and 2048MB total.

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; there

fore, your computer can operate with only one DIMM installed.

About Memory

Before increasing the memory

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.

Note

DDR

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.

Note

75System Expansion

Check the type of memory installed in your computer and refer to the memory config­uration chart before purchasing a memory.

Specification: PC2100/2700/3200(184 pin DDR SDRAM DIMM)

Replacing the 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.

Installing a memory

ã Push the latch inward

so that the memory is
securely locked in the
socket.
