2.6 Jumper
Clear RTC RAM (3-pin CLRTC)
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You
can clear the CMOS memory of date, time, and system setup parameters by
erasing the CMOS RTC RAM data. The onboard button cell battery powers the
RAM data in CMOS, which include system setup information such as system
passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on
pins 2-3 for about 5~10 seconds, then move the cap back to pins 1-2.
3. Plug the power cord and turn ON the computer.
4. Hold down the <Del> key during the boot process and enter BIOS setup
to re-enter data.
Except when clearing the RTC RAM, never remove the cap on CLRTC jumper
default position. Removing the cap will cause system boot failure!
If the steps above do not help, remove the onboard battery and move the
jumper 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 limitation, AC power off is required prior using C.P.R.
