3.6 Central Processing Unit (CPU)
This motherboard provides a ZIF (Zero Insertion Force) Socket 370. The CPU for
your motherboard should have a fan attached to it to prevent overheating. If this is
not the case, then purchase a fan before you turn on your system.
WARNING!
Be sure that there is sufficient air circulation across the processor’s
heatsink by regularly checking that your CPU fan is working. Without sufficient
circulation, the processor could overheat and damage both the processor and the
motherboard. You may install an auxiliary fan, if necessary.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF
socket and open it by first pulling the lever sideways away from the socket then
upwards to a 90-degree angle. Insert the CPU with the correct orientation as shown.
The notched corner should point towards the end of the lever. Because the CPU has
a corner pin for two of the four corners, the CPU will only fit in the orientation as
shown. The picture below is for reference only; you should have a CPU fan that
covers the face of the CPU. With the added weight of the CPU fan, no force is
required to insert the CPU. Once completely inserted, push the socket’s lever down
while holding down the CPU.
NOTE: Do not forget to set the correct Bus Frequency and Multiple for your Socket
370 processor or else your system may start. Socket 370 processors provide internal
thermal sensing so that a socket mounted thermal resistor is not needed.
CAUTION: Be careful not to scrape the motherboard when mounting a clamp-
style processor fan or else damage may occur to the motherboard.
