Jumpers; Clear Rtc Ram (Clrtc1) - Asus P4PE-X User Manual

Jumpers

1. Keyboard power (3-pin KBPWR1)
This jumper allows you to enable or disable the keyboard wake-up feature. Set
this jumper to pins 2-3 (+5VSB) if you wish to wake up the computer when you
press a key on the keyboard (the default is the Space Bar). This feature
requires an ATX power supply that can supply at least 1A on the +5VSB lead,
and a corresponding setting in the BIOS (see section 2.5.1 Power Up Control).

2. Clear RTC RAM (CLRTC1)

This jumper allows clearing the Real Time Clock (RTC) RAM in CMOS. You
can clear the CMOS memory of date, time, and system setup information by
erasing the CMOS RTC RAM data.
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.

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 BIOS can automatically reset
parameter settings to default values.
