3. Once completely inserted, press the CPU firmly and close the socket
lever until it snaps into its locked position.
4. Install an Intel fan heatsink.
5. Place the CPU fan and heatsink on the CPU. The heatsink should entirely
cover the CPU. Carefully attach the heatsink locking brace to the plastic
clips on the socket base. With the added weight of the CPU fan and
heatsink locking brace, no extra force is required to keep the CPU in
place
2.4.2 Installing the CPU
Follow these steps to install a CPU:
1. Locate the Socket 478 and open it by
pulling the lever gently sideways away
from the socket. Then lift the lever
upwards. The socket lever must be fully
opened (90 to 100 degrees).
2. Insert the CPU with the correct
orientation. The gold arrow of the CPU
must be oriented toward the inner
corner of the socket base nearest to the
hinge of the lever handle.
Do not neglect to set the correct Bus Frequency and Multiple (frequency
multiple setting is available only on unlocked processors) for your Socket
478 processor or else boot-up may not be possible. Socket 478 processors
provide internal thermal sensing: a socket mounted thermal resistor is
not needed.
Take care not to scrape the motherboard surface when mounting a clamp-
style processor fan, or else damage may occur. When mounting a
heatsink onto your CPU, make sure that exposed CPU capacitors do not
touch the heatsink, or damage may occur!
The CPU fits in one orientation and should drop easily into place. Do not
force the CPU into the socket to avoid bending the pins. If the CPU
does not fit, check its alignment and look for bent pins.
