Chapter 2: Hardware information

3. Clear RTC RAM (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 RAM

data in CMOS, that include system setup information such as system

passwords, is powered by the onboard button cell battery.

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.

Except when clearing the RTC RAM, never remove the cap on CLRTC

jumper default position. Removing the cap will cause system boot

failure!

1. The USB device wake-up feature requires a power supply that can

provide 500mA on the +5VSB lead for each USB port. Otherwise,

the system would not power up.

2. The total current consumed must NOT exceed the power supply

capability (+5VSB) whether under normal condition or in sleep

mode.
