CPU & Cooler Installaton
When you are nstallng the CPU, make sure the CPU has a cooler attached on the top to prevent overheatng . Meanwhle, do not forget to apply some thermal paste on CPU 
before nstallng the heat snk/cooler fan for better heat dsperson. 
Follow  the  steps  below  to  nstall  the  CPU  &  cooler  correctly.  Wrong  nstallaton  wll 
cause the damage of your CPU & manboard.
Open the load level.          
1. Lft  the  load  lever  up  to  fully  open 
poston2.
The CPU socket has a plastc cap on 
t to protect the contact from damage. 
Before you  nstall CPU, always cover 
t  to  protect  the  socket  pn.  Romove 
the cap (as the arrow shows).
3. After confirmng the CPU drecton for 
correct matng, put down the CPU n 
the socket housng frame. Be sure to 
grasp on the edge of the CPU base. 
Note  that  the  algnment  keys  are 
matched.

well  nto  the  socket.  If  not,  take  out 
the  CPU  wth  pure  vertcal  moton 
and renstall.5. Engage the load lever whle pressng 
down lghtly onto the load plate.6.
Secure  the  lever  near  the  hook  end 
under the retenton tab.7.Make sure the four hooks are n por-
per  poston  before  you  nstall  the

Memory Populaton Rule
Please refer to the followng llustratons for memory populaton rules.
Dual-Channel mode Populaton Rule
In  Dual-Channel  mode,  the  memory  modules  can  transmt  and  receve  data  wth  two 
data bus lnes smultaneously. Enablng Dual-Channel mode can enhance the system 
performance.  The  followng  llustratons  explan  the  populaton  rules  for  Dual-Channel 
mode.

   DIMM3
   DIMM4
 
 2  DIMM1

   DIMM3
   DIMM4
Important
DDR3 memory modules are not  nterchangeable wth DDR2, and the DDR3 standard 
s  not  backwards  compatble.  You  should  always  nstall  DDR3  memory  modules n 
the DDR3 DIMM slots.
In Dual-Channel mode, make sure that you  nstall memory modules of the 
same type and densty n dfferent channel DIMM slots.
To  ensure a successful system boot-up, always  nsert the memory modules nto the 
DIMM1 first.
Due to the chpset resource deployment, the system densty wll only be detected up  to 15+GB (not full 16GB) when each DIMM s nstalled wth a 4GB memory module.

wre to the connectors, always note that the red wre s the postve and should be con-
nected to the +12V; the black wre  s Ground and should be connected to GND. If the 
manboard has a System Hardware Montor chpset on-board, you must use a specally
