Installing an Upgrade Processor
Install the upgrade processor as follows.
1. Remove the processor currently in the system (see “Removing the Processor” in the
previous section).
Before picking up the processor, reduce static discharge by touching
the metal chassis.
2. Align the triangle on the corner of the processor with the letters “CPU1” on the system
board.
3. Carefully align the processor pins with the socket pin holes and set the processor into the
socket.
! If aligned correctly and the pins are not bent, the processor seats in the socket without
forcing.
! If the processor does not seat, check for correct alignment and bent pins.
4. Pivot the lever down and press it in towards the socket until it locks in place.
Using the wrong heat sink or no heat sink can damage the processor,
system board, or both. Ensure that the update processor has the correct heat sink (refer to the
documentation that comes with the kit).
