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 2-3 (default) to pins 1-2. Keep the

cap on pins 1-2 for about 5~10 seconds, then move the cap back to

pins 2-3.

4. Re-install 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.
