(3) CMOS RAM Clear (3-pin): JP3
A battery must be used to retain the motherboard configuration in CMOS RAM short 1-
2 pins of JP3 to store the CMOS data.
To clear the CMOS, follow the procedure below:
1. Turn off the system and unplug the AC power
2. Remove ATX power cable from ATX power connector
3. Locate JP3 and short pins 2-3 for a few seconds
4. Return JP3 to its normal setting by shorting pins 1-2
5. Connect ATX power cable back to ATX power connector
Note: When should clear CMOS
1. Troubleshooting
2. Forget password
3. After over clocking system boot fail
