2.2. Install
Pentium
®
4 CPU and Heatsink Supporting-Base
This motherboard provides a ZIF (
Z
ero
I
nsertion
F
orce) Socket 478 to install Intel
®
Pentium
®
4 CPU. The CPU you bought should have a kit of heatsink and cooling fan
along with. If that’s not the case, buy one specially designed for Pentium
®
4 Socket
478.
1. Locate the 478-pin ZIF socket
on the motherboard. Fasten the
Retention Module Base onto the
motherboard.
ATTENTION:
If you are using
chassis specially designed for
Pentium
®
4, please pay attention to
the location of Metal Studs or
Spacers if they are already installed
on the chassis. Be careful not let the
Metal Studs or Spacers contact the
printed circuit wire or parts on the
PCB.
2. Pull the CPU socket lever
sideways away from the socket
and then upwards to 90 degree.
Insert the CPU with the correct
orientation. Do not use extra
force to insert CPU; it only fits
in one orientation. Close down
the socket lever while holding
down the CPU.
3. Put the heatsink faces down
onto the CPU until it completely
covers the CPU.
4. Put the Fan and Retention
Mechanism Assembly onto the
heatsink. Make sure all the four
Retention Locks at each side of
the Fan and Retention
Mechanism Assembly snap into
the Retention Holes.
