Hardware Setup 2-1
Chapter 2. Hardware Setup
Before the Installation: Turn off the power supply switch (fully turn off the +5V standby power), or
disconnect the power cord before installing or unplugging any connectors or add-on cards. Failing to do
so may cause the motherboard components or add-on cards to malfunction or damaged.
2-1. Install The Motherboard
Most computer chassis have a base with many mounting holes to allow a motherboard to be securely
attached and at the same time, prevented from short circuits. There are two ways to attach the
motherboard to the chassis base:
1. use with studs
2. or use with spacers
In principle, the best way to attach the board is to
studs. Only if you are unable to do this should
you attach the board with spacers. Line up the
holes on the board with the mounting holes on the
chassis. If the holes line up and there are screw
holes, you can attach the board with studs. If the
holes line up and there are only slots, you can
only attach with spacers. Take the tip of the
spacers and insert them into the slots. After doing
this to all the slots, you can slide the board into
position aligned with slots. After the board has been positioned, check to make sure everything is OK
before putting the chassis back on.
ATTENTION: To prevent shorting the PCB circuit, please REMOVE the metal studs or spacers if they
are already fastened on the chassis base and are without mounting-holes on the motherboard to align with.

2-2. Install CPU, Heatsink and Fan Assembly
Please pay attention to the following notices
before installing the CPU and heatsink/fan
assembly.
1. Always use the processor with the
Heatsink and Fan Assembly installed.
2. Do not touch the pins on the processor.
3. If you ever need to reinstall the Heatsink
and fan Assembly, please clean the
heatsink surface and apply new thermal
interface material first.
1. Pull out the socket locking lever slightly,
then lift it up.
2. Align the corner with triangle mark of the
processor with the marking on the motherboard,
and then place the processor vertical down into
the socket.
3. Lower the locking lever to the fully locked
position.
4. Apply thermal interface material.
5. Place the heatsink and fan assembly onto
the retention frame. Match the heatsink clip
with the socket mounting lug. Hook the spring
clip to the mounting lug.
AT8

Hardware Setup 2-3
6. On the other side, push the retention clip
straight down to lock into the plastic lug on the
retention frame.
7. Turn the cam lever to lock into the retention
frame.
8. Attach the four-pin power plug from the
heatsink and fan assembly to the CPU FAN
connector.
For detailed information on how to install your
heatsink and fan assembly, please refer to the
instruction manual that came packed with the
heatsink and fan assembly you bought.

Hardware Setup 2-5
To reach the performance of Dual Channel DDR, the following rules must be obeyed:
• When installing TWO DIMM modules: Install DIMM modules of the same type and size for
slots [DIMM1]+[DIMM2] or slots [DIMM3]+[DIMM4].
• When installing FOUR DIMM modules: Install DIMM modules of the same type and size for
slots [DIMM1]+[DIMM2], and slots [DIMM3]+[DIMM4].
NOTE: Usually there is no hardware or BIOS setup requires after adding or removing memory modules,
but you will have to clear the CMOS memory first if any memory module related problem occurs.
Power off the computer and unplug the AC power cord before installing or removing memory modules.
1. Locate the DIMM slot on the board.
2. Hold two edges of the DIMM module
carefully, keep away of touching its
connectors.
3. Align the notch key on the module with the
rib on the slot.
4. Firmly press the module into the slots until
the ejector tabs at both sides of the slot
automatically snaps into the mounting notch.
Do not force the DIMM module in with extra
force as the DIMM module only fit in one direction.
5. To remove the DIMM modules, push the two ejector tabs on the slot outward simultaneously, and
then pull out the DIMM module.
ATTENTION: Static electricity can damage the electronic components of the computer or optional
boards. Before starting these procedures, ensure that you are discharged of static electricity by touching a
grounded metal object briefly.

graphics card to enable the CrossFire mode.
Note that there’s a unique CrossFire!
DMS-59!connector on the bracket of a
CrossFire!Edition graphics card.
2. Insert the CrossFire!Edition graphics
card into PCIEXP2 (Master) slots on the
motherboard.
3. You also need a CrossFire!compatible
PCI Express graphics card for the slave slot.
Note that there’s no CrossFire!DMS-59!
connector on the bracket of the slave card.
4. Insert the CrossFire!compatible PCI
Express graphics into the PCIEXP1 (Slave) slot.

2-5. Connectors, Headers and Switches
Here we will show you all of the connectors, headers and switches, and how to connect them. Please read
the entire section for necessary information before attempting to finish all the hardware installation inside
the computer chassis. A complete enlarged layout diagram is shown in Chapter 1 for all the positions of
connectors and headers on the board that you may refer to.
WARNING: Always power off the computer and unplug the AC power cord before adding or removing
any peripheral or component. Failing to do so may cause severe damage to your motherboard and/or
peripherals. Plug in the AC power cord only after you have carefully checked everything.
(1). ATX Power Input Connectors
This motherboard provides two power connectors to connect ATX12V power supplier.
NOTE: This 24-pin power connector “ATXPWR1” is compliant to the former 20-pin type. Pay attention
to the orientation when attaching the power cord. (Pin-11, 12, 23, and 24 should be left un-connected).
Note: It is recommended to connect to a power with 350W, 20A +5VDC capacity at least for heavily
loaded system, and a 2A +5VSB capacity at least for supporting wake-up features.
The auxiliary 12V power connector [ATX4P1] provides an additional power
source for devices added on PCI Express slots. It is highly recommended to
attach 12V power from the power supplier for the best system stability.
AT8

(2). FAN Power Connectors
These connectors each provide power to the cooling fans installed in your system.
• CPUFAN1: CPU Fan Power Connector
• SYSFAN1: System Fan Power Connector
• NBFAN1, AUXFAN1, AUXFAN2 AUXFAN3: Auxiliary Fan Power Connector
WARNING: These fan connectors are not jumpers. DO NOT place jumper caps on these connectors.
User’s Manual

2-12 Chapter 2
(3). CMOS Memory Clearing Header
This header uses a jumper cap to clear the CMOS memory.
• Pin 1-2 shorted (default): Normal operation.
• Pin 2-3 shorted: Clear CMOS memory.
WARNING: Turn the power off first (including the +5V standby power) before clearing the CMOS
memory. Failing to do so may cause your system to work abnormally or malfunction.
Internal Audio Connectors (4).
These connectors connect to the audio output of internal CD-ROM drive or add-on card.
