3-4 Replacing the CPU (CG/DG/CM/EG models)

The shape and replacement method of the CPU fan may be different depending on

the model.

1. Clamps on both sides of the CPU fasten the fan tightly to the CPU socket.

raise the handle(1) , release the clamps, and then spread them outward(2).

2. After releasing the clamps, lift and remove the CPU fan from the socket.

3. Raise the handle on the CPU socket to unlock the CPU.

℘

Consult your service representatives before replacing the CPU.

ℙ

25System Expansion

Align the identifying marks at the corners of the new CPU and socket, and carefully

install the CPU in the socket. Lower the handle to lock the CPU in place.

6. Lift the clamps and slide them into the rails at the corners of the CPU socket, and

place the fan into the socket. Push down the handles to lock the clamps.

4. Lift the CPU straight up. Be careful not to damage the pins at the bottom of the CPU.

In some models, you can not lower one of the handles of the clamps all the way down.

For removing CPUs in these models, release the clamp on the other side first. For

installing CPUs in these models, lock this clamp first.

3-5. 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.

Note

Use a 2.5V DDR SDRAM DIMM.(The shape of the memory may be different depend-

ing on the model) DDR SDRAM enhances the rate of data transmission of the

SDRAM and looks different from SDRAM.

DDR

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

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

Note: 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

Static electricity can damage memory modules; be sure to minimize the static electric-

ity when replacing memory.

Make sure to replace the memory of the same type as the installed memory.

DIMM is different from SIMM in that it is configured for 64 bit operation; therefore,

your computer can operate with only one DIMM installed.

29System Expansion

Purchasing a memory

Check the type of memory installed in your computer and refer to the memory configura-

tion chart before purchasing a memory.

Specification: PC2700/3200(184 pin DDR SDRAM DIMM)

Speed: 333MHz(166MHz X 2), 400MHz(200MHz X 2)
