the rear panel provides the following connectors:
HaRdWaRe SetuP
this  chapter  tells  you  how  to  install  the  CPu,  memory  modules,  and  expansion 
cards, as well as how to setup the jumpers on the mainboard. it also provides the 
instructions on connecting the peripheral devices, such as the mouse, keyboard, etc. While doing the installation, be careful in holding the components and follow the installation procedures.
CPu & Cooler installation for aM
When you are installing the CPu, make sure the CPu has a cooler attached on the 
top to prevent overheating. Meanwhile, do not forget to apply some thermal paste 
on CPu before installing the heat sink/cooler fan for better heat dispersion. 
Follow the steps below to install the CPu & cooler correctly. Wrong installation will 
cause the damage of your CPu & mainboard.

Pull  the  lever  sideways  away  from  the  socket.  Make  sure  to  raise  the  lever  up  to  a  90-degree angle.
Look  for  the  gold  arrow  of  the  CPu. the  gold 
arrow  should  point  as  shown  in  the  picture.  the 
CPu can only fit in the correct orientation.
if the CPu is correctly installed, the pins should be 
completely embedded into the socket and can not be seen. Please note that any violation of the cor-rect installation procedures may cause permanent damages to your mainboard.  
Press  the  CPu  down  firmly  into  the  socket  and 
close the lever.  as the CPu is likely to move while 
the  lever  is  being  closed,  always  close  the  lever with  your  fingers  pressing  tightly  on  top  of  the 
CPu to make sure the CPu is properly and com-pletely embedded into the socket.
Position the cooling set onto the retention mecha-nism. Hook one end of the clip to hook first.
then  press  down  the  other  end  of  the  clip  to 
fasten  the  cooling  set  on  the  top  of  the  retention mechanism. Locate the Fix Lever and lift up it.
Fasten down the lever.
attach the CPu Fan cable to the CPu fan connec
-tor on the mainboard.

Mainboard  photos  shown  in  this  section  are  for demonstration  of  the  cooler  in-
stallation  for  Socket  aM  CPu  only. the  appearance  of  your  mainboard  may 
vary depending on the model you purchase.
While disconnecting the Safety Hook from the fixed bolt, it is necessary to keep an eye on your fingers, because once the Safety Hook is disconnected from the fixed bolt, the fixed lever will spring back instantly.

installing Memory Modulesthe memory module has only one notch on the center and will only fit in the 
right orientation.
insert  the  memory  module  vertically  into  the  diMM  slot. then  push  it  in  until 
the golden finger on the memory module is deeply inserted in the  diMM slot. 
the plastic clip at each side of the  diMM slot will automatically close when the 
memory module is properly seated. you can barely see the golden finger if the memory module is properly inserted in the diMM slot.
Manually check if the memory module has been locked in place by the diMM 
slot clips at the sides.

ddR memory modules are not interchangeable with  ddR2 and the ddR stan
-
dard  is  not  backwards  compatible.  you  should  always  install ddR  memory 
modules in the ddR diMM slots.
in  dual-Channel mode, make sure that you install memory modules of the same 
type and density in different channel diMM slots.  
to  enable  successful  system  boot-up,  always  insert  the  memory  modules  into the diMM first.*

Make  sure  that  all  the  power  connectors  are  connected  to  proper  atX  power 
supplies to ensure stable operation of the mainboard.
Power supply of  50 watts (and above) is highly recommended for system sta
-bility.

ide Connector: ide
this  connector  supports ide  hard  disk  drives,  optical  disk  drives  and  other  ide 
devices.
iMPoRtant
if  you  install  two  ide  devices  on  the  same  cable,  you  must  configure  the  drives 
to  cable  select  mode  or  separately  to  master  /  slave  mode  by  setting  jumpers. 
Refer  to  ide  device  documentation  supplied  by  the  vendors  for  jumper  setting 
instructions.
Serial ata Connector: Sata ~ 6
this  connector  is  a  high-speed  Serial  ata  interface  port. each  connector  can 
connect to one Serial ata device.
iMPoRtant
Please do not fold the Serial  ata cable into 90-degree angle.  otherwise, data loss 
may occur during transmission.
Fan Power Connectors: CPuFan, SySFan, SySFan2
the fan power connectors support system cooling fan with +2V. When connect-ing  the  wire  to  the  connectors,  always  note  that  the  red  wire  is  the  positive  and 
should  be  connected  to  the  +2V;  the  black  wire  is  Ground  and  should  be  con-
nected  to  Gnd.  if  the  mainboard  has  a  System  Hardware  Monitor  chipset  on-
board, you must use a specially designed fan with speed sensor to take advantage 
of the CPu fan control.
