HARDWARE SETUP
This chapter tells you how to install the CPU, CPU cooler set and memory modules, as well
as how to setup the jumpers on the mainboard. It also provides the instructions on
connecting the peripheral devices. While doing the installation, be careful in holding the
components and follow the installation procedures.
CPU Installation Procedures for Socket AM2
1. Please turn off the power and unplug the power
cord before installing the CPU.
2. Pull the lever sideways away from the socket.
Make sure to raise the lever up to a 90-degree
angle.
3. Look for the gold arrow of the CPU. The gold
arrow should point as shown in the picture. The
CPU can only fit in the correct orientation.
4. If the CPU is correctly installed, the pins should
be completely embedded into the socket and
can not be seen. Please note that any violation
of the correct installation procedures may cause
permanent damages to your mainboard.
5. Press the CPU down firmly into the socket and
close the lever. As the CPU is likely to move
while the lever is being closed, always close the
lever with your fingers pressing tightly on top of
the CPU to make sure the CPU is properly and
completely embedded into the socket.
Important:
Overheating will seriously damage the CPU and system. Always make sure the cooler set
can work properly to protect the CPU from overheating.
Make sure that you apply an even layer of heat sink paste (or thermal tape) between the
CPU and the heatsink to enhance heat dissipation.

Installing AMD Socket AM2 CPU Cooler Set
Volt
When you are installing the CPU, make sure the CPU has a heat sink and a cooling fan
attached on the top to prevent overheating. If you do not have the heat sink and cooling fan,
contact your dealer to purchase and install them before turning on the computer.
Important:
Mainboard photos shown in this section are for demonstration of the cooler installation for
Socket AM2 CPU only. The appearance of your mainboard may vary depending on the
model you purchase.
1. Position the cooling set onto the retention
mechanism. Hook one end of the clip to hook
first.
2. Then press down the other end of the clip to
fasten the cooling set on the top of the retention
mechanism. Locate the Fix Lever and lift up it.
3. Fasten down the lever.
4. Attach the CPU Fan cable to the CPU fan
connector on the mainboard.
Important:
While disconnecting the Safety Hook from the fixed bolt, it is necessary to keep an eye on
your fingers, because once the Safety Hook is disconnected from the fixed bolt, the fixed
lever will spring back instantly.
Installing Memory Modules
1. The memory module has only one notch on the center and will only fit in the right
orientation.
2. Insert the memory module vertically into the DIMM slot. Then push it in until the
golden finger on the memory module is deeply inserted in the DIMM slot. You can
barely see the golden finger if the memory module is properly inserted in the DIMM
slot.
3. The plastic clip at each side of the DIMM slot will automatically close.
Notch
Important:
DDR2 memory modules are not interchangeable with DDR and the DDR2 standard is not
backwards compatible. You should always install DDR2 memory modules in the DDR2
DIMM slots.
In Dual-Channel mode, make sure that you install memory modules of the same type and
density in different channel DIMM slots.
To enable successful system boot-up, always insert the memory modules into the DIMM1
first.

Clear CMOS Jumper: JBAT1
There is a CMOS RAM onboard that has a power supply from an
external battery to keep the data of system configuration. With the
CMOS RAM, the system can automatically boot OS every time it
is turned on. If you want to clear the system configuration, set the
jumper to clear data.
Important:
You can clear CMOS by shorting 2-3 pin while the system is off. Then return to 1-2 pin
position. Avoid clearing the CMOS while the system is on; it will damage the mainboard.
PCI (Peripheral Component Interconnect) Express Slot
The PCI Express slot supports the PCI Express interface expansion card.
The PCI Express x16 slot supports up to 4.0 GB/s transfer rate.
The PCI Express x1 slot supports up to 250 MB/s transfer rate.

Page 12
PCI (Peripheral Component Interconnect) Slot
The PCI slot supports LAN card, SCSI card, USB card, and other add-on cards that
comply with PCI specifications.
Important:
When adding or removing expansion cards, make sure that you unplug the power supply
first. Meanwhile, read the documentation for the expansion card to configure any
necessary hardware or software settings for the expansion card, such as jumpers,
switches or BIOS configuration.
PCI Interrupt Request Routing
The IRQ, acronym of interrupt request line and pronounced I-R-Q, are hardware lines
over which devices can send interrupt signals to the microprocessor. The PCI IRQ pins
are typically connected to the PCI bus pins as follows:
Order 1 Order 2 Order 3 Order 4
PCI Slot 1 INT Y# INT Z# INT W# INT X#
PCI Slot 2 INT X# INT Y# INT Z# INT W#

Advance DRAM Configuration > MCT Timing Mode
This field has the capacity to automatically detect all of the DRAM timing. If you set this field
to [Manual], you can select the DRAM timing manually.
Advance DRAM Configuration > 1T/2T Memory Timing
This setting controls the SDRAM command rate. The default value is 2T (T=clock cycles).
2T is more stable than 1T, but 1T is faster than 2T.
Adjust DDR2 Memory Frequency
This item allows you to select the memory frequency programming method. If select Auto,
the memory speed will be based on SPDs. If select Limit, the memory speed will not exceed
the specified value. If select Manual, the memory specified will be programmed regardless
of SPD.
Adjust PCIE Frequency
This item allows you to select the PCI Express frequency (in MHz). Select the number
between [100]~[150] for needed frequency.
Auto Disable PCI Clock
This item is used to auto disable the PCI slots. When set to [Enabled], the system will
remove (turn off) clocks from empty PCI slots to minimize the electromagnetic interference
(EMI).
CPU Voltage
This setting is used to adjust the CPU core voltage(Vcore) and offers users a tool to
overclock the system.
Memory Voltage
Adjusting the DDR voltage can increase the DDR speed. Any changes made to this setting
may cause a stability issue, so changing the DDR voltage for long-term purpose is NOT
recommended.
Spread Spectrum Configuration
When the motherboard’s clock generator pulses, the extreme values (spikes) of the pulses
creates EMI (Electromagnetic Interference). The Spread Spectrum function reduces the EMI
generated by modulating the pulses so that the spikes of the pulses are reduced to flatter
curves. If you do not have any EMI problem, leave the setting at Disabled for optimal system
stability and performance. But if you are plagued by EMI, set to Enabled for EMI reduction.
Remember to disable Spread Spectrum if you are overclocking because even a slight jitter
can introduce a temporary boost in clock speed which may just cause your overclocked
processor to lock up.
Important:
If you do not have any EMI problem, leave the setting at [Disabled] for optimal system
stability and performance. But if you are plagued by EMI, select the value of Spread
Spectrum for EMI reduction.
The greater the Spread Spectrum value is, the greater the EMI is reduced, and the system
will become less stable. For the most suitable Spread Spectrum value, please consult your
local EMI regulation.
Remember to disable Spread Spectrum if you are overclocking because even a slight jitter
can introduce a temporary boost in clock speed which may just cause your overclocked
processor to lock up.
