Incorrectly doing overclock/overvoltage may result in damage to CPU, chipset, or memory and reduce the useful life of these components. This page is for advanced users only and we recommend you not to alter the default settings to prevent system instability or other unexpected results. (Inadequately alter ing the settings may result in system's failure to boot. If this occurs, clear the CMOS values and reset the board to default values.) • When the System Voltage Optimized item blinks in red, it is recommended that you set the System Voltage Control item to Auto to optimize the system voltage settings.

Whether the system will work stably with the overclock/overvoltage settings you made is
dependent on your overall system configurations. Incorrectly doing overclock/overvoltage
may result in damage to CPU, chipset, or memory and reduce the useful life of these
components. This page is for advanced users only and we recommend you not to alter the
default settings to prevent system instability or other unexpected results. (Inadequately alter
ing the settings may result in system's failure to boot. If this occurs, clear the CMOS values
and reset the board to default values.)

When the
System Voltage Optimized
item blinks in red, it is recommended that you set
the
System Voltage Control
item to
Auto
to optimize the system voltage settings.
