U
pgrading the Microprocessor
To take advantage of future options in speed and func-
tionality, you can replace the microprocessor on your
system board with any Dell-supported microprocessor
upgrade. Call your Dell sales representative for informa-
tion on available microprocessor upgrades.
The following items are included in a microprocessor
upgrade kit:
•
The new microprocessor chip
•
A new heat sink with thermal interface adhesive
The following procedure describes how to replace the
microprocessor.
NOTES: Dell recommends that only a technically knowl-
edgeable person perform this procedure.
1. Remove the computer cover according to the
instructions in "Removing the Computer Cover"
in Chapter 5.
CAUTION: See "Protecting Against Electro-
static Discharge" in the safety instructions at
the front of this guide.
2. Rotate the power supply out of the way according
to the instructions in "Rotating the Power Supply
Away From the System Board" in Chapter 5.
3. See Figure 6-1 to locate the microprocessor socket
(labeled "MICROPROCESSOR") on the system
board.
4. Remove the metal clip that secures the heat sink
to the microprocessor socket. Then remove the
heat sink from the microprocessor chip.
Press down on the folded part of the clip with a small
screwdriver to release the clip (see Figure 6-9).

5. Remove the microprocessor chip from the socket.
CAUTION: Be careful not to bend any of the
pins when removing the microprocessor chip
from its socket. Bending the pins can perma-
nently damage the microprocessor chip.
Your microprocessor socket is a zero insertion force
(ZIF) socket with a lever-type handle that secures the
chip in, or releases it from, the socket.
