Static Electricity Precautions
1. Don’t take this motherboard and components out of their original staticproof package until you are ready to install them.
2 . While installing, please wear a grounded wrist strap if possible. If you don’t
have a wrist strap, discharge static electricity by touching the bare metal of
the system chassis.
3. Carefully hold this motherboard by its edges. Do not touch those components unless it is absolutely necessary. Put this motherboard on the top of
static-protection package with component side facing up while installing.
Pre-Installation Inspection
1. Inspect this motherboard whether there are any damages to components and
connectors on the board.
2 . If you suspect this motherboard has been damaged, do not connect power to
the system. Contact your motherboard vendor about those damages.

CPU Installation Procedure
The following illustration shows CPU installation components.
A. Opening of the Load Plate
· Put your thumb on the tail of the load plate
and press the tail down.
· Rotate the load plate to fully open position.
B. Disengaging of the Load Lever
· Hold the hook of lever and pull it to the left
side to clear retention tab.
· Rotate the load lever to fully open position.
C. Removing the Cap
· Be careful not to touch the contact at any
time.
D. Inserting the Package
· Grasp the package. Ensure to grasp on the
edge of the substrate.
· Make sure pin 1 indicator is on your bottomleft side.
· Aim at the socket and place the package
carefully into the socket by purely vertical
motion.
E. Closing the Load Plate
· Rotate the load plate onto the package IHS
(Intergraded Heat Spreader).
· Engage the load lever while pressing down
lightly onto the load plate.
· Secure the load lever with the hook under
retention tab.
F. Fasten the cooling fan supporting base
onto the CPU socket on the motherboard.
G. Make sure the CPU fan is plugged to the
CPU fan connector. Please refer to the
CPU cooling fan user’s manual for more
detail installation procedure.

Installing Memory Modules
This motherboard accommodates four memory modules. It can support four 240-pin
DDR3 1066/800. The total memory capacity is 8 GB.
DDR3 SDRAM memory module table
Memory module Memory Bus
DDR3 800 400 MHz
DDR3 1066 533 MHz
You must install at least one module in any of the four slots. Total memory capacity
is 8 GB.
The four DDR3 memory sockets (DDR3_1, DDR3_2, DDR3_3 and DDR3_4) are
divided into two channels and each channel has two memory sockets as following:
Channel A: DDR3_1, DDR3_2
ff
Channel B: DDR3_3, DDR3_4

1. For best performance and compatibility, we recommend that users give
priority to the orange DIMMs (DDR3_1/DDR3_3) when installing DIMMs.
2. We suggest users not mix memory type. It is recommended to use the
same brand and type memory on this motherboard.
3. You may not populate three DIMMs at one time, and if the four DIMMs
are populated at one time, the memory will run at 800MHz.
Do not remove any memory module from its antistatic packaging until you
are ready to install it on the motherboard. Handle the modules only by
their edges. Do not touch the components or metal parts. Always wear a
grounding strap when you handle the modules.

Jumper Setting
Connecting two pins with a jumper cap is SHORT; removing a jumper cap from these
pins, OPEN.
CLR_CMOS: Clear CMOS Jumper
You may need to clear the CMOS memory if the settings in the Setup Utility are
incorrect and prevent your motherboard from operating. To clear the CMOS memory,
disconnect all the power cables from the motherboard and then move the jumper cap
into the CLEAR setting for a few seconds.

CLR_CMOS
Note:
1. “Bold white line” on the motherboard indicates Pin1.
2. Before installing this motherboard, make sure jumper CLR_CMOS is
under Normal setting.
3. To avoid the system unstability after clearing CMOS, we recommend
users to enter the main BIOS setting page to “Load Optimal Defaults” and
then “Save Changes and Exit”.

BIOS Setup Utility
The BIOS Setup Utility records settings and information of your computer. If the
system malfunction happens for incorrect Setup Utility configuration, you can use
the clear CMOS jumper to clear the CMOS memory, or hold down the Page Up key
while rebooting your computer. Holding down the Page Up key also clears the setup
information. You can run the setup utility and manually change the configuration.
Software & Applications
The support DVD-ROM/CD-ROM contains all useful software, necessary drivers and
utility programs to properly run our products. Simply insert the support disk into
your DVD-ROM/CD-ROM drive. An Auto Setup screen automatically pops out, and
then you can go on the auto-installing.
