ReaR PaneL
the rear panel provides the following connectors:
the pin-pad side of LGa 775 CPu.
the surface of LGa 775 CPu.
Remember to apply some thermal paste on it for better heat dispersion.
note: to reach the 8-channel sound effect, the 7th and 8th channels must be out-
put from front panel if you purchase the mainboard with  audio jacks
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 Procedures for LGa775
When you are installing the CPu, make sure to install the cooler to prevent over-
heating.  if you do not have the CPu cooler, consult your dealer before turning on 
the computer.

Follow the steps below to install the CPu & cooler correctly. Wrong installation will 
cause the damage of your CPu & mainboard.the CPu socket has a plastic cap on it to protect the 
contact  from  damage.  Before  you  install  the  CPu, 
always cover it to protect the socket pin.
Remove the cap from lever hinge side.
the pins of socket reveal.
open the load lever.
Lift the load lever up and open the load plate.
after  confirming  the  CPu  direction  for  correct  mat
-
ing, put down the CPu in the socket housing frame. 
Be sure to grasp on the edge of the CPu base.  note 
that the alignment  keys are matched.
Visually  inspect  if  the  CPu  is  seated  well  into  the 
socket. if  not,  take  out  the  CPu  with  pure  vertical 
motion and reinstall.
Cover the load plate onto the package. 
Press down the load lever lightly onto the load plate, and  then  secure  the  lever  with  the  hook  under  re-tention tab.
align the holes on the mainboard with the heatsink. 
Push down the cooler until its four clips get wedged into the holes of the mainboard.
Press  the  four  hooks  down  to  fasten  the  cooler. 
then  rotate  the  locking  switch  (refer  to  the  correct 
direction marked on it) to lock the hooks.
turn  over  the  mainboard  to  confirm  that  the  clip-
ends are correctly inserted.
Finally,  attach  the  CPu  Fan  cable  to  the  CPu  fan 
connector on the mainboard.
iMPoRtant
Read the CPu status in BioS.
Whenever  CPu  is  not  installed,  always  protect  your  CPu  socket  pin  with  the 
plastic cap covered to avoid damaging. Mainboard photos shown in this section are  for  demonstration  of  the  CPu/cooler  installation  only.  the  appearance  of 
your mainboard may vary depending on the model you purchase.

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.

ddR2 memory modules are not interchangeable with ddR and the ddR2 stan
-
dard  is  not  backwards  compatible.  you  should  always  install ddR2  memory 
modules in the ddR2 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.*

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 ~ 4
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.
