Safety Instructions  
To reduce the risk of fire, electric shocks, and injury, always follow basic  
safety precautions.  
Remember to remove power off your computer by disconnecting the AC  
main source before removing or installing any equipment from/to the  
computer chassis.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
Preparing the Motherboard  
Installing the CPU  
Be very careful when handling the CPU. Hold  
the processor only by the edges and do not  
touch the contacts on the motherboard or  
CPU. Any physical damage to the  
motherbard pins will void the warranty.  
Use the following procedure to install the  
CPU onto the motherboard:  
Unhook the socket lever by pushing down and  
away from the socket.  
Pull the socket lever back and the load plate will  
automatically lift. There is a protective  
socket cover within the CPU socket to  
protect the socket when there is no CPU  
installed.  
Remove the protective socket cover from the  
CPU Socket in a straight up motion.  
Note: It is a good idea to save the cover so that whenever you remove the CPU  
you have a safe place to store it.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
Align the notches in the processor with the  
notches on the socket.  
Lower the processor straight down into the  
socket without tilting or sliding it into the  
socket  
Note: Make sure the CPU is fully seated and level.  
Lower the load plate so it is resting on the  
CPU.  
Align notches with notches on the CPU  
Pull back the socket lever again to ensure the  
load plate tip engages under the shoulder  
screw cap.  
Carefully close and latch the lever.  
Load plate tip under screw cap  
Installing the CPU Fan  
There are many different fan types that can be used with this motherboard.  
Follow the instruction that came with you fan assembly. Be sure that the fan  
orientation is correct for your chassis type and your fan assembly.  
Please note that there are 2 sets of mounting holes, the holes surrounded in  
white are to be used for Socket 1156 heatsinks and are labeled. The other holes  
are to be used for Socket 775 heatsinks.  
In most cases, the Socket 1156 mounting holes will be used.

Installing System Memory (DIMMs)  
Your new motherboard has four 240-pin slots for DDR3 memory. These slots  
support 1GB, 2GB, 4GB DDR3 technologies. There must be at least one  
memory bank populated to ensure normal operation. Use the following the  
recommendations for installing memory.  
One DIMM: If using 1 DIMM (Single Channel), install into: DIMM slot 1.  
Two DIMMs: If using 2 DIMMs (Dual Channel), install into: DIMM slots  
1 and 3.  
Four DIMMS: If using 4 DIMMs (Dual Channel), install into: DIMM  
slots 2, 1, 4, and 3.  
DIMM Slot 2  
DIMM Slot 1  
DIMM Slot 4  
DIMM Slot 3  
Use the following procedure to install memory DIMMs. Note that there is only  
one gap near the center of the DIMM slot. This slot matches the slot on the  
memory DIMM to ensure the component is installed properly.  
1. Unlock a DIMM slot by pressing the module clips outward.  
2. Align the memory module to the DIMM slot, and insert the module  
vertically into the DIMM slot. The plastic clips at both sides of the DIMM  
slot automatically lock the DIMM into the connector.  
Installing the Motherboard  
The sequence of installing the motherboard into a system case depends on the  
chassis you are using and if you are replacing an existing motherboard or  
working with an empty system case. Determine if it would be easier to make all  
the connections prior to this step or to secure the motherboard and then make  
all the connections. It is normally easier to secure the motherboard first.  
Use the following procedure to install the I/O shield and secure the  
motherboard into the chassis.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
Installing the I/O Shield  
The motherboard kit comes with an I/O shield that is used to block radio  
frequency transmissions, protects internal components from dust and foreign  
objects, and promotes correct airflow within the chassis.  
Before installing the motherboard, install the I/O shield from the inside of the  
chassis. Press the I/O shield into place and make sure it fits securely.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Securing the Motherboard into a System Case  
Most system cases have a base with mounting studs or spacers to allow the  
motherboard to be secured to the chassis and help to prevent short circuits. If  
there are studs that do not align with a mounting hole on the motherboard, it is  
recommended that you remove that stud to prevent the possibility of a short  
circuit. In most cases, it is recommended to secure the motherboard using a  
minimum of nine (9) spacers and screws.  
1. Carefully place the motherboard onto the stand offs located inside the  
chassis.  
2. Align the mounting holes with the stand offs.  
3. Align the connectors to the I/O shield.  
4. Ensure that the fan assembly is aligned with the chassis vents according to  
the fan assembly instruction.  
5. Secure the motherboard with a recommended minimum of nine (9) screws.

Expansion Slots  
PCI Slots  
The PCI slot supports many expansion cards such as a LAN card, USB card,  
SCSI card and other cards that comply with PCI specifications. When installing  
a card into the PCI slot, be sure that it is fully seated. Secure the card’s metal  
bracket to the chassis back panel with the screw used to hold the blank cover.  
PCI Express x1 Slots  
There is one PCI Express x1 slot that is designed to accommodate PCIe x1  
cards, such as an EVGA Killer Xeno Network Card or Sound Card. The x1 slot  
provides 250 MB/sec bandwidth.  
PCI Express x16/x8/x4 Slots  
These PCI Express slots are reserved for Graphic Cards and PCI Express x1  
and x4 devices. The design of this motherboard supports multiple Graphic Card  
technology.  
When installing a PCI Express Graphic Card, be sure the retention clip snaps  
and locks the card into place. If the card is not seated properly, it could cause a  
short across the pins. Secure the card’s metal bracket to the chassis back panel  
with the screw used to hold the blank cover.

Onboard Buttons  
These onboard buttons include RESET, POWER and Clear CMOS. These  
functions allow you to easily reset the system, turn on/off the system, or clear  
the CMOS.  
Clear CMOS Button  
The motherboard uses the CMOS RAM to store all the set parameters. The  
CMOS can be cleared by pressing the Clear CMOS button either onboard  
or on the external I/O Panel.  
External Clear CMOS Button  
RESET and POWER Button  
These onboard buttons allow you to easily turn on/off the system. These  
buttons allow for easy debugging and testing of the system during  
troubleshooting situations.  
The POWER button with LED indicates the system’s status. When the system  
is powered on, the LED remains a solid red.  
The RESET button with an integrated LED indicates the activity status of the  
hard disk drives and will flicker accordingly.
