Jumpers

1. Clear RTC RAM (3-pin CLRTC)
This header allows you to clear the CMOS RTC RAM data.
DN-300-R2 Clear RTC RAM
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Move the jumper cap from pins 2-3 (default) to pins 1-2. Keep the cap on
pins 1-2 for about 5~10 seconds, then move the cap back to pins 2-3.
3. Plug the power cord and turn ON the computer.
4. Hold down the <F2> key during the boot process and enter BIOS setup
to reenter data.
CAUTION! Except when clearing the RTC RAM, never remove the cap on
CLRTC jumper default position. Removing the cap will cause system boot
failure!
NOTES:
• 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 so the
BIOS can automatically reset parameter settings to default values.
• This jumper will just load BIOS defaults, and will not clear BIOS password.
