Chapter 1: Product Introduction
10. AURA RGB headers
The RGB headers allow you to connect RGB LED strips.
The RGB headers support 5050 RGB multi-color LED strips (12V/G/R/B),
with a maximum power rating of 3A (12V), and no longer than 3m.
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.
•
The LED strip will only light up
when the system is powered on.
•
The LED strip is purchased separately.
11. Clear CMOS header
This header allows you to clear the CMOS RTC RAM data of the system setup
information such as date, time, and system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Use a metal object such as a screwdriver to short the two pins.
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.
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.
12. COM Port header
This header is for a serial (COM) port. Connect the serial port module cable to
this header, then install the module to a slot opening at the back of the system
chassis.
13. Front panel audio header
This header is for a chassis-mounted front panel audio I/O module that
supports HD audio standard. Connect one end of the front panel audio I/O
module cable to this header.
•
We recommend that you connect a high-definition front panel
audio module to this header to avail of the motherboard’s high-
definition audio capability.
•
If you want to connect a high-definition front panel audio module
to this header, set the Front Panel Type item in the BIOS setup
to [HD Audio]. By default, this header is set to [HD Audio].
