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. For the latest information about CPU, please visit http://www.msi.com.tw/cpusupport.

Introduction to LGA 775 CPU

The surface of LGA 775 CPU. Remember to apply some thermal paste on it for better heat dispersion.

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.

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.

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.
