1.9 Jumpers

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 <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!

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.
