CPU Overclocking Button
Press  this  button  to  overclock  your  CPU  and  the  button  will  light  blue.  To  return  to  the  defaults,  press 
this button again.
HDMI Port 
The  HDMI  port  is  HDCP  compliant  and  supports  Dolby  True  HD  and  DTS  HD 
Master Audio formats. It also supports up to 192KHz/24bit 8-channel LPCM au-
dio output. You can use this port to connect your HDMI-supported monitor. The maximum supported reso -
lution is 1920x1200, but the actual resolutions supported are dependent on the monitor being used.
 • When removing the cable connected to a back panel connector, first remove the cable from your 
device and then remove it from the motherboard.
 • When  removing  the  cable,  pull  it  straight  out  from  the  connector.  Do  not  rock  it  side  to  side  to 
prevent an electrical short inside the cable connector.
O.C.
After installing the HDMI device, make sure to set the default sound playback device to HDMI. (The item 
name may differ depending on your operating system. The screenshot below is from Windows 7.)
In  Windows  7,  select  Start>Control  Panel>Hardware 
and  Sound>Sound>Playback,  set  Intel(R) Display Au-
dio to the default playback device. 
eSATA/USB Combo Connector
This connector supports SATA 3Gb/s and USB 2.0/1.1 specification. Use the port to connect an external 
SATA device. The Intel Z68 Chipset supports RAID function. Refer to Chapter 5, "Configuring SATA 
Hard Drive(s)," for instructions on configuring a RAID array. Or use this port for USB devices such as a 
USB keyboard/mouse, USB printer, USB flash drive and etc.

ATX_12V_2X4/ATX (2x4 12V Power Connector and 2x12 Main Power Connector)
  With the use of the power connector, the power supply can supply enough stable power to all the com-
ponents	 on	the	 motherboard.	 Before	connecting	 the	power	 connector,	 first	make	 sure	the	power	 supply	
is  turned  off  and  all  devices  are  properly  installed. The  power  connector  possesses  a  foolproof  design. 
Connect  the  power  supply  cable  to  the  power  connector  in  the  correct  orientation. The  12V  power  con -
nector mainly supplies power to the CPU. If the 12V power connector is not connected, the computer will 
not start.
To meet expansion requirements, it is recommended that a power supply that can withstand high 
power  consumption  be  used  (500W  or  greater).  If  a  power  supply  is  used  that  does  not  provide 
the required power, the result can lead to an unstable or unbootable system.

 All fan headers on this motherboard are 4-pin and support fan speed control function. Most fan headers 
possess  a  foolproof  insertion  design.  When  connecting  a  fan  cable,  be  sure  to  connect  it  in  the  correct 
orientation (the black connector wire is the ground wire). The speed control function requires the use of 
a fan with fan speed control design. For optimum heat dissipation, it is recommended that a system fan 
be installed inside the chassis.

9) F_PANEL (Front Panel Header)
  Connect  the  power  switch,  reset  switch,  speaker,  chassis  intrusion  switch/sensor  and  system  status 
indicator  on  the  chassis  to  this  header  according  to  the  pin  assignments  below.  Note  the  positive  and 
negative pins before connecting the cables.
PW
 •  (Power Switch, Red): 
	 Connects	 to	the	 power	 switch	 on	the	 chassis	 front	panel.	 You	may	 configure	 the	way	 to	turn	 off	your	
system  using  the  power  switch  (refer  to  Chapter  2,  "BIOS  Setup,"  "Power  Management  Setup,"  for 
more information).
SPEAK
 •  (Speaker, Orange): 
 Connects to the speaker on the chassis front panel. The system reports system startup status by is-
suing a beep code. One single short beep will be heard if no problem is detected at system startup. If 
a problem is detected, the BIOS may issue beeps in different patterns to indicate the problem. Refer 
to Chapter 5, "Troubleshooting," for information about beep codes.
HD
 •  (Hard Drive Activity LED, Blue)
 Connects to the hard drive activity LED on the chassis front panel. The LED is on when the hard drive 
is reading or writing data.
RES
 •  (Reset Switch, Green):
 Connects to the reset switch on the chassis front panel. Press the reset switch to restart the computer 
if the computer freezes and fails to perform a normal restart.
CI
 •  (Chassis Intrusion Header, Gray):
 Connects  to  the  chassis  intrusion  switch/sensor  on  the  chassis  that  can  detect  if  the  chassis  cover 
has been removed. This function requires a chassis with a chassis intrusion switch/sensor. MSG/PWR
 •  (Message/Power/Sleep LED, Yellow/Purple):
The  front  panel  design  may  differ  by  chassis.  A  front  panel  module  mainly  consists  of  power 
switch, reset switch, power LED, hard drive activity LED, speaker and etc. When connecting your 
chassis  front  panel  module  to  this  header,  make  sure  the  wire  assignments  and  the  pin  assign -
ments are matched correctly.

10) F_AUDIO (Front Panel Audio Header)
	 The 	front	 panel 	audio 	header	 supports 	Intel 	High	 Definition 	audio 	(HD) 	and	 AC'97 	audio. 	You	 may	 connect 	your chassis front panel audio module to this header. Make sure the wire assignments of the module con -
nector  match  the  pin  assignments  of  the  motherboard  header.  Incorrect  connection  between  the  module 
connector and the motherboard header will make the device unable to work\
 or even damage it.
The front panel audio header supports HD audio by default. If your chassis provides an AC'97  • front  panel  audio  module,  refer  to  the  instructions  on  how  to  activate AC'97  functionality  via 
the	audio	software	in	Chapter	5,	"Configuring	2/4/5.1/7.1-Channel	 Audio."Audio signals will be present on both of the front and back panel audio connections simultane - •
ously. If you want to mute the back panel audio (only supported when using an HD front panel 
audio	module),	refer	to	Chapter	5,	"Configuring	2/4/5.1/7.1-Channel	 Audio."Some chassis provide a front panel audio module that has separated connectors on each wire  •
instead  of  a  single  plug.  For  information  about  connecting  the  front  panel  audio  module  that 
has different wire assignments, please contact the chassis manufacturer.
11)  SPDIF_O (S/PDIF Out Header)
  This header supports digital S/PDIF Out and connects a S/PDIF digital audio cable (provided by expan-
sion cards) for digital audio output from your motherboard to certain expansion cards like graphics cards 
and sound cards. For example, some graphics cards may require you to use a S/PDIF digital audio cable 
for  digital  audio  output  from  your  motherboard  to  your  graphics  card  if  you  wish  to  connect  an  HDMI 
display  to the graphics card and have digital audio output from the HDMI display at the same time. For 
information  about  connecting  the  S/PDIF  digital  audio  cable,  carefully  read  the  manual  for  your  expan -
sion card.

optional USB bracket. For purchasing the optional USB bracket, please co\
ntact the local dealer.
Do not plug the IEEE 1394 bracket (2x5-pin) cable into the USB 2.0/1.1\
 header. •
Prior  to  installing  the  USB  bracket,  be  sure  to  turn  off  your  computer  and  unplug  the  power 
 • cord from the power outlet to prevent damage to the USB bracket.
When  the  system  is  in  S4/S5  mode,  only  the  USB  ports  routed  to  the  F_USB1  header  can  sup-
port the ON/OFF Charge function.
