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:

4.
Turn OFF the computer and unplug the power cord.
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.
Plug the power cord and turn ON the computer.
Hold down the <Del> key during the boot process and enter BIOS setup
to reenter data.
CAUTION! Except when clearing the RTC RAM, never remove the cap on
CLRTC jumper default position. Removing the cap will cause system boot
failure!
NOTES:
• If the steps above do not help, remove the onboard battery and move the
jumper again to clear the CMOS RTC RAM data. After clearing the CMOS,
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 CPU
Parameter Recall (C.P.R) feature. Shut down and reboot the system so the
BIOS can automatically reset parameter settings to default values. •
