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.
