Installing an Upgrade Processor

a Locate the corner markers:

•
on the processor socket—a dot.
•
b Position the processor over the socket, with it's corner marker
facing the corner marker on the socket.
c Place the processor into the socket.
d Lower the lever to lock the processor into place.
e Replace the heatsink and fasten the clip, if the heatsink is not
attached to the processor.
6 Set switches 1, 2, 3, 4 and 7 on the system board for the correct
processor speed. Refer to the section "System Board Connectors and
Switches" on page 95. If you use an Intel Overdrive processor, refer
to the instruction leaflet supplied with the processor to see whether
you should change the position of any switches on the system board.
7 Remove the old VRM by unclipping the two white tabs, and then slide
the module up and out of the socket. Slide the new VRM into the
socket, pressing it down firmly. Push the white tabs back into place.
The VRM module goes in one way only.
8 Replace the computer's power supply and cover. Reconnect all
cables and power cords.
Switch on the PC and verify that the new processor is recognized by the
Power-On-Self-Test.
