Chapter 2 INSTALLATION
2-5
Central Processing Unit (CPU)
The motherboard provides a 321-pin ZIF Socket 7. The CPU should
have a fan attached to it to prevent overheating. If your CPU did not
come with a fan, then purchase a fan before you turn on your system.
Apply thermal jelly to the CPU top and then install the fan onto the
CPU.
NOTE: Without a fan, the CPU will overheat and cause damage to both the
CPU and the motherboard. To install a CPU, locate the ZIF socket and
open it by first pulling the lever sideways away from the socket’s “Lock”
then upwards to a 90-degree right angle. Insert the CPU with the correct
orientation. Look to see that the pins are denser on one half compared to
the other half. The picture is for reference only, you should have a CPU fan
that will cover the face of the CPU. With the added weight of the CPU fan,
no force is required to insert the CPU. Once completely inserted, hold
down the fan and close the socket’s lever.
NOTE: You must set the CPU External Clock (BUS) Frequency Selection”
and “CPU to BUS Frequency Ratio” depending on the CPU that you
install.
