Central Processing Unit (CPU)
The motherboard provides a 321-pin ZIF Socket 7. The
CPU that came with the 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. Apply
thermal jelly to the CPU top and then install the fan onto
the CPU.
NOTE:
Without a fan, the CPU may 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 to insert the CPU
with the correct orientation. You should have a CPU fan that
will cover the surface 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 Frequency
Selection” and “CPU Internal Frequency Ratio”
depending on the CPU that you install.
