and to re-enter data.
Except when clearing the RTC RAM , never remove the cap from the
CLRTC jumper default position. Removing the cap will cause system boot
failure!
▪
If the steps above do not help, remove the onboard battery and place a
metal object or jumper cap again to clear the CMOS RTC RAM data. After
the CMOS clearance, reinstall the battery.
▪
You do not need to clear the RTC when the system hangs due to
overclocking. For system failure due to overclocking, use the C.P.R. (CPU
Parameter Recall) feature. Shut down and reboot the system so the
BIOS can automatically reset parameter settings to default values.
▪
Due to the chipset behavior, AC power off is required to enable C.P.R.
function. You must turn off and on the power supply or unplug and plug
the power cord before rebooting the system.

CPU Over Voltage jumper (3-pin CPU_OV)
The CPU Over Voltage jumper allows you to set a higher CPU voltage for a flexible
overclocking system, depending on the type of the installed CPU. To gain more CPU voltage
setting, insert the jumper to pins 2-3. To go back to its default CPU voltage setting, insert
the jumper to pins 1-2.
