This jumper allows you to enable the Clear CMOS switch. You can clear the 

CMOS memory of date, time, and system setup parameters by erasing the 

CMOS RTC RAM data. The onboard clr CMOS switch helps you easily to 

clear the system setup information such as system passwords. See page 

2-35 for details.

 

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 to enable the 

CLRTC function.

3.  Press down the clr CMOS button and again to release it.
4.  Plug the power cord and turn ON the computer.
5.  Hold down the <Del> key during the boot process and enter BIOS setup 

to re-enter data.

The clr CMOS button will not function until the jumper cap on CLRTC_EN is 

moved to the ENABLE 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.

•  To prevent accidental pressing of the Clear CMOS switch, the CLRTC_EN 

jumper default setting disables the switch.
