Product Introduction
1.1 Before you proceed
Take note of the following precautions before you install motherboard components or change
any motherboard settings.
• Unplug the power cord from the wall socket before touching any component.
• Before handling components, use a grounded wrist strap or touch a safely grounded
object or a metal object, such as the power supply case, to avoid damaging them due
to static electricity.
• Hold components by the edges to avoid touching the ICs on them.
• Whenever you uninstall any component, place it on a grounded antistatic pad or in the
bag that came with the component.
• Before you install or remove any component, ensure that the ATX power supply is
switched off or the power cord is detached from the power supply. Failure to do so
may cause severe damage to the motherboard, peripherals, or components.
Chapter 1: Product Introduction
• The pin definitions in this chapter are for reference only. The pin names depend on

Before you install or remove any component, ensure that the ATX power supply is switched
off or the power cord is detached from the power supply. Failure to do so may cause severe
damage to the motherboard, peripherals, or components.
• 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.

13. RTC Battery header
The RTC Battery header allows you to connect the lithium CMOS battery.
14. 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 button cell battery and short the two
pins again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the button
cell battery.
15. 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.
16. 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.
