Clear RTC

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 CPU 

Parameter Recall (C.P.R.) feature. Shut down and reboot the system, then 

the BIOS automatically resets parameter settings to default values.
