FCC-B Radio Frequency Interference Statement

This equipment has been
tested and found to comply
with the limits for a Class B
digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accor­dance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the measures listed
below.

† Reorient or relocate the receiving antenna.
† Increase the separation between the equipment and receiver.
† Connect the equipment into an outlet on a circuit different from that to

which the receiver is connected.

† Consult the dealer or an experienced radio/television technician for help.

Notice 1

The changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.

Notice 2

Shielded interface cables and A.C. power cord, if any, must be used in order to
comply with the emission limits.

Hardware Setup

CPU (Central Processing Unit)

This mainboard supports Intel® Pentium 4 in LGA 775 package. When you are installing
the CPU, make sure to install the cooler to prevent overheating. If you do not
have the CPU cooler, consult your dealer before turning on the computer.

Important

Overheating

Overheating will seriously damage the CPU and system. Always make sure
the cooling fan can work properly to protect the CPU from overheating. Make
sure that you apply an even layer of thermal paste (or thermal tape) between
the CPU and the heatsink to enhance heat dissipation.

Replaceing the CPU

While replacing the CPU, always turn off the ATX power supply or unplug the
power supply’s power cord from the grounded outlet first to ensure the safety
of CPU.

Overclocking

This mainboard is designed to support overclocking. However, please make
sure your components are able to tolerate such abnormal setting, while
doing overclocking. Any attempt to operate beyond product specifications is
not recommended. We do not guarantee the damages or risks caused

by inadequate operation or beyond product specifications.

MS-7346 Mainboard

Important

1.Confirm if your CPU cooler is firmly installed before turning on your system.

2. Do not touch the CPU socket pins to avoid damaging.

3. The availability of the CPU land side cover depends on your CPU packing.

2.Remove the cap from lever hinge
side (as the arrow shows).

1.The CPU socket has a plastic cap
on it to protect the contact from
damage. Before you install the CPU,
always cover it to protect the socket
pin.

CPU & Cooler Installation

When you are installing the CPU, make sure the CPU has a cooler attached on
the top to prevent overheating. Meanwhile, do not forget to apply some thermal

paste on CPU before installing the heat sink/cooler fan for better heat dispersion.
Follow the steps below to install the CPU & cooler correctly. Wrong installation will
cause the damage of your CPU & mainboard.

3.The pins of socket reveal.

4.Open the load lever.

Hardware Setup

6.After confirming the CPU direction
for correct mating, put down the
CPU in the socket housing frame.
Be sure to grasp on the edge of
the CPU base. Note that the align­ment keys are matched.

8.Cover the load plate onto the
package.

7.Visually inspect if the CPU is
seated well into the socket. If not,
take out the CPU with pure vertical
motion and reinstall.

10. Align the holes on the mainboard
with the heatsink. Push down the
cooler until its four clips get
wedged into the holes of the
mainboard.

12.Turn over the mainboard to con­firm that the clip-ends are cor­rectly inserted.

11.Press the four hooks down to fas­ten the cooler. Then rotate the lock­ing switch (refer to the correct di­rection marked on it) to lock the
hooks.

9.Press down the load lever lightly

onto the load plate, and then se­cure the lever with the hook under
retention tab.

Important

1. Read the CPU status in BIOS (Chapter 3).

2. Whenever CPU is not installed, always protect your CPU socket pin with the
plastic cap covered (shown in Figure 1) to avoid damaging.

3. Mainboard photos shown in this section are for demonstration of the CPU/
cooler installation only. The appearance of your mainboard may vary depend­ing on the model you purchase.

In Dual-Channel mode, the memory modules can transmit and receive data with two
data bus lines simultaneously. Enabling Dual-Channel mode can enhance the system
performance. Please refer to the following illustrations for population rules under

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.

- Due to the chipset resource deployment, the system density will only be
detected up to 7+GB (not full 8GB) when each DIMM is installed with a 2GB
memory module.

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.

3. The plastic clip at each side of the DIMM slot will automatically close.

Important

You can barely see the golden finger if the memory module is properly inserted
in the DIMM slot.

Please do not fold the Serial ATA cable into 90-degree angle. Otherwise,
data loss may occur during transmission.

Fan Power Connectors: CPUFAN, SYSFAN1~3

The fan power connectors support system cooling fan with +12V. When connecting
the wire to the connectors, always note that the red wire is the positive and should
be connected to the +12V; the black wire is Ground and should be connected to GND.
If the mainboard has a System Hardware Monitor chipset on-board, you must use a
specially designed fan with speed sensor to take advantage of the CPU fan control.
