• Actual lighting and color will vary with LED strip.
• If your LED strip does not light up, check if the RGB LED extension cable and the
RGB LED strip are connected in the correct orientation, and the 12V connector is
aligned with the 12V header on the motherboard.
• The LED strip will only light up when the system is powered on.
• The LED strip is purchased separately.
13. Clear CMOS header
The Clear CMOS header allows you to clear the Real Time Clock (RTC) RAM
in the CMOS, which contains the date, time, system passwords, and system
setup parameters.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Short-circuit pin 1-2 with a metal object or jumper cap for about 5-10
seconds.
3. Plug 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.
DO NOT short-circuit the pins except when clearing the RTC RAM. Short-circuiting or
placing a jumper cap will cause system boot failure!
If the steps above do not help, remove the onboard battery and short the two pins again to
clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery.
14. COM Port header
The COM (Serial) Port header allows you to connect a COM port module.
Connect the COM port module cable to this header, then install the module to
a slot opening on the system chassis.
The COM port module is purchased separately.
15. Front Panel Audio header
The Front Panel Audio header is for a chassis-mounted front panel audio I/O
module that supports HD Audio. Connect one end of the front panel audio I/O
module cable to this header.
We recommend that you connect a high-denition front panel audio
module to this header to avail of the motherboard’s high-denition audio
capability.
