processor. The processor you bought should include a
heatsink and cooling fan kit along with. If that’s not
the case, buy one specially designed for Pentium
®
4
Socket 478. Please refer to figure 2-3 to install the
processor.
1. Locate the Socket 478. Fasten the heatsink
supporting-base onto the motherboard.
Attention
If you are using chassis specially designed for
Pentium

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 processor socket lever sideways away
from the socket and then upwards to 90 degrees.
Insert the processor with the correct orientation.
Do not use extra force to insert processor; it only
fits in one orientation. Push down the socket lever
while holding down the processor.
3. Put the heatsink face down onto the processor until
it completely covers the processor.
4. Put the heatsink supporting-cover onto the
heatsink. Make sure all four locking clasps on each
side of the supporting cover reach in the locking
holes.
5. Push down the retaining clip on both sides of the
supporting cover to lock together with the
supporting base. Watch the direction you push
down on the clip.
6. The heatsink supporting cover and base should
now firmly lock together with the heatsink inside.
Attention
Do not forget to set the correct bus frequency and
multiple for your processor.
