2.6 Jumper
Clear RTC RAM (3-pin CLRTC_SW)
This jumper allows you to enable the clr CMOS switch on the back I/O. You can
clear the CMOS memory and system setup parameters by erasing the CMOS RTC
RAM data. The clr CMOS switch on the back I/O helps you easily clear the system
setup information such as system passwords.
To erase the RTC RAM:
1. Press down the clr CMOS switch on the back I/O.
2. Hold down the key during the boot process and enter BIOS setup to
re-enter data.
• The clr CMOS switch will not function if the CLRTC_SW jumper is moved to
the Disable position.
• Ensure to re-enter your previous BIOS settings after you clear the CMOS.
• You do not need to clear the RTC when the system hangs due to CPU
overclocking. With the C.P.R. (CPU Parameter Recall) feature, shut down
and reboot the system so the BIOS can automatically reset CPU parameter
settings to default values.
