ASUS V-Series P5G45

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.  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!
