There is CMOS Jumper :
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 in 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.
There is a CMOS switch on the back I/O of the motherboard.
1.) Press down the “clr CMOS” switch on the back I/O.
2.) Hold down the < Del > key during the boot process and enter BIOS setup to re-enter data.
( It is the CLRTC_SW jumper )
1. The “clr CMOS” switch will not function if the CLRTC_SW jumper is moved to the disable position.
2. Ensure to re-enter your previous BIOS settings after you clear the CMOS.
3. 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.
