2-4 CPU Installation
Avoid Static Electricity
The Intel P4 processors and your motherboard contain sensitive electronic components that
can be easily damaged by static electricity. We recommend that you leave the processor in
its original packaging until you are ready to install it. You should only touch the edges of
the processor, NEVER touch the processor pins to avoid static discharge.
First take a moment to inspect your CPU for obvious damage due to shipping or handling.
Be sure that no noticeable damage exists before proceeding. You should have the following
items:
1 Intel P4 processor.
1 good heatsink and fan assembly.
Step 1
The following figure shows the processor socket. Note that the release lever on the right
side of the socket is down and latched. This position is used to lock the processor in place.
The lever must be raised to install the processor. To do this, first push the lever sideways to
unlatch it, then raise it all the way up (approximately 90 degrees).
Step 2
The processor pin array at the top two corners is angled and has no pins in the corners.
Notice that at the top of the socket on the motherboard (near where it says "Socket 478")
the corners also do not have positions for pins. The processor must be positioned so the
pins match up properly. When you do that, the corner of processor that is cut off will be
positioned next to the release pivot.
It should take no force to install the processor, this is a zero insertion force (ZIF) socket. If
it takes any force you are doing something wrong. Check the pin alignment and also make
sure the release lever is raised up completely.
