3. Remove the expansion card edge support by removing the single
screw.
4. Remove any DRAM SIMMs that are installed in the card. Make sure
to use proper antistatic precautions when handling the SIMMs.
5. Remove the three screws at the corners of the heat sink, but do not
attempt to remove the heat sink yet. Do not remove the two screws in
the middle of the heat sink. Keep the three screws in a safe place.
6. The heat sink is attached to the processor via an adhesive, heat-
conducting pad. Rotate the heat sink back and forth in the plane of
the CPU card to disconnect the thermal pad from the heat sink. If the
thermal pad detaches from the processor instead of the heat sink,
remove the pad from the heat sink. You will not need the thermal
pad.
7. From the four corners of the card, remove the three 1/4 in. standoffs,
three nylon washers, and the screw that attach the CPU card to the
motherboard.
8. Remove the CPU card by pulling it gently and firmly from its
connectors.
Step 2. Install the Upgrade CPU Card
To insert the new CPU card, perform the following steps.
1. Insert the CPU card firmly into the horizontal connectors.
2. Reattach the CPU card with the three 1/4 in. standoffs and three
washers (which correspond to the holes in the corners of the heat
sink), and the screw.
3. Remove the backing from one side of the new thermal pad and place
it on the processor with the adhesive side down.
4. Remove the backing from the other side of the thermal pad and place
the heat sink onto the processor, making sure to line up the mounting
holes at the corners of the heat sink with the matching holes on the
CPU card.
5. Reattach the heat sink to the CPU card using the three screws you
previously removed.
6. Reinsert the DRAM SIMMs into the sockets in the new CPU card. If
you have two SIMMs, you can install them in the two slots closest to
the heat sink or in the two outermost slots.
7. Reinstall the expansion card edge support with the single screw.
