ASUS P6T Deluxe V2 用户手册

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.

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 the CMOS 

clearance, 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 C.P.R. (CPU 

Parameter Recall) feature. Shut down and reboot the system so the BIOS 

can automatically reset parameter settings to default values.

•  Due to the chipset behavior, AC power off is required to enable C.P.R. 

function. You must turn off and on the power supply or unplug and plug the 

power cord before rebooting the system.

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.
