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. clr CMOS switch behavior System power state G3* S5* S0 (DOS mode) S0 (OS mode) S1 S3 S4 Clearing CMOS ** *G3: Power off without +5VSB power (AC power loss); S5: Power off with +5VSB power **The system shuts dowm immediately. • The clr CMOS switch will not function if the CLRTC_SW jumper is moved to the Disable position, but the shutdwon function in S0 mode (DOS mode) still works. • 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. If the system hangs due to overclocking of memory timing or chipset voltage and the power button fails to function, pressing down the clr CMOS switch will shut down the system and clear CMOS simultaneously.
