CPU Fan Protection
The CPU Fan Protection function has the capability of monitoring the
CPU fan during system boot-up and will automatically power-off the
system once it has detected that the CPU fan did not rotate. This
preventive measure has been added to protect the CPU from
damage and insure a safe computing environment. Refer to “CPU
Fan Connector with CPU Fan Protection Function” in chapter 2 and
“CPU Fan Protection” in the PC Health Status section in chapter 3
for more information.
Over Voltage
The Over Voltage function allows you to manually adjust to a higher
core voltage that is supplied to the CPU. Although this function is
supported, we do not recommend that you use a higher voltage
because unstable current may be supplied to the system board
causing damage. Refer to “CPU Vcore Select” in the Frequency/
Voltage Control section in chapter 3 for more information.
CPU Overclocking
The CPU Overclocking function allows you to adjust the processor’s
bus clock by 1MHz stepping. However, overclocking may result to
the processor’s or system’s instability and are not guaranteed to
provide better system performance. Refer to “Clock By Slight Adjust”
in the Frequency/Voltage Control section in chapter 3 for more
information.
