1.2.9 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 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 C.P.R. (CPU Parameter Recall) feature.

Shut down and reboot the system so the BIOS can automatically reset parameter

settings to default values.
