Introducing the Motherboard

Installing the Motherboard
Safety Precautions
• Follow these safety precautions when installing the motherboard
• Wear a grounding strap attached to a grounded device to avoid damage from
static electricity
• Discharge static electricity by touching the metal case of a safely gr
object before working on the motherboard
• Leave components in the static-proof bags they came in
• Hold all circuit boards by the edges. Do not bend circuit boards
Choosing a Computer Case
There are many types of computer cases on the market. The motherboard
the specifications for the ATX system case. First, some features on the mo
implemented by cabling connectors on the motherboard to indicators and sw
system case. Make sure that your case supports all the features required. Second
A754 supports one or two floppy diskette drives and four enhanced IDE drive
that your case has sufficient power and space for all drives that you intend t
Most cases have a choice of I/O templates in the rear panel. Make sure
template in the case matches the I/O ports installed on the rear edge of the
This motherboard carries an ATX form factor of 305 X 220 mm. Choos
accommodates this form factor.
Installing the Motherboard in a Case
Refer to the following illustration and instructions for installing the motherbo
Most system cases have mounting brackets installed in the case, which corresp
in the motherboard. Place the motherboard over the mounting brackets a
motherboard onto the mounting brackets with screws.
Ensure that your case has an I/O template that supports the I/O ports and ex
on your motherboard.

Installing the Motherboard
Checking Jumper Settings
This section explains how to set jumpers for correct configuration of the mothe
Setting Jumpers
Use the motherboard jumpers to set system configuration options. Jumpers with
one pin are numbered. When setting the jumpers, ensure that the jumper caps are
the correct pins.
The illustrations show a 2-pin jumper. When
the jumper cap is placed on both pins, the
jumper is SHORT. If you remove the jumper
cap, or place the jumper cap on just one pin,
the jumper is OPEN.
This illustration shows a 3-pin jumper. Pins
1 and 2 are SHORT
SHORT OPEN
Do not over-tighten the screws as this can stress the motherboard

2 Connect the case cooling fan connector to CASFAN1.
3 Connect the Northbridge cooling fan connector to NBFAN1.
4 Connect the case switches and indicator LEDs to the PANEL1. If there are 3
pins in the case LED cable, connect to SJ1.
5 Connect the standard power supply connector to ATX1.
6 Connect the auxiliary case power supply connector to ATX12V.
Connecting 20/24-pin power cable
Users please note that the 20-pin and 24-pin power cables can both be
to the ATX1 connector. With the 20-pin power cable, just align the 20-
cable with the pin 1 of the ATX1 connector. However, using 20-pin po
may cause the system to become unbootable or unstable because of in
electricity. A minimum power of 300W is recommended for a fully-c
system.

Installing the Motherboard
1 Install your CPU. Pull up the lever away from the
socket and lift up to 90-degree angle.
2 Locate the CPU cut edge (the corner with the pin
hold noticeably missing). Align and insert the CPU
correctly.
3 Press the lever down and apply thermal grease on
top of the CPU.
4 Put the CPU Fan down on the retention module and
snap the four retention legs of the cooling fan into
place.
5 Flip the levers over to lock the heat sink in place and
connect the CPU cooling Fan power cable to the
CPUFAN connector. This completes the installa-
tion.
CPU Installation Procedure
The following illustration shows CPU installation components.
To achieve better airflow rates and heat dissipation, we sugges
a high quality fan with 4800 rpm at least. CPU fan and hea
tion procedures may vary with the type of CPU fan/heatsink
form and size of fan/heatsink may also vary.
This motherboard has a Socket 754 processor socket. When choosing a proce
the performance requirements of the system. Performance is based on the pro
the clock speed and system bus frequency of the processor, and the quanti
cache memory and external cache memory.
Warning: Over-clocking components can adversely affect the
the system and introduce errors into your system. Over-cloc
permanently damage the motherboard by generating excess
components that are run beyond the rated limits.
Before installing the Processor
This motherboard automatically determines the CPU clock frequency an
frequency for the processor. You may be able to change these settings by m
to jumpers on the motherboard, or changing the settings in the system Setu
strongly recommend that you do not over-clock processors or other comp
faster than their rated speed.
Also, install the cooling fan in a well lit work area so that you can clearly
see the motherboard and processor socket.

Installing the Motherboard
Installation Procedure
Refer to the following to install the memory modules.
1 This motherboard supports unbuffered DDR SDRAM only.
2 Push the latches on each side of the DIMM slot down.
3 Align the memory module with the slot. The DIMM slots are keyed
notches and the DIMMs are keyed with cutouts so that they can only
installed correctly.
4 Check that the cutouts on the DIMM module edge connector match the notche
in the DIMM slot.
5 Install the DIMM module into the slot and press it firmly down until it
correctly. The slot latches are levered upwards and latch on to the edges o
the DIMM.
6 Install any remaining DIMM modules.
