P5XV3 System Board User’s Manual
2.2.2 Installing a Processor
The system board is equipped with a 321-pin Zero Insertion
Force (ZIF) socket The ZIF socket is designed for easy removal of
an old processor and easy insertion of an upgrade processor. If
you need to apply excessive force to insert the processor, you are
not installing the processor correctly.
1. To raise the handle of the ZIF socket, push it down, slightly pull
it out to the side, then raise it as far as it will go. It may be
necessary to initially apply a small amount of sideways force to
free the handle from its retaining “tab”. Once clear of the “tab”,
the handle will open relatively easily. The top plate will slide
back.
2. Insert the processor until the pins are in their corresponding
holes. Make sure pin 1 of the processor is aligned with pin 1
of the socket. To prevent improper processor installation, the
ZIF socket has a Plug/Keying mechanism. Several holes in the
socket are plugged so that the processor will go in only one
way.
3. Push the handle down until the handle locks into place. The
top plate will slide forward.
Warning:
The processor must be kept cool by using a fan with
heatsink. Otherwise, the processor will overheat and damage
the processor and the system board.
