Clear RTC RAM (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. Remove the onboard battery.
3. 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.
4. Reinstall the battery.
5. Plug the power cord and turn ON the computer.
6. Hold down the 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!
• Make sure to re-enter your previous BIOS settings after you clear the
CMOS.
• 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.
