Hardware Setup

CPU (Central Processing Unit)

The mainboard supports AMD® Athlon64/ X2 & Sempron processors. The mainboard uses a CPU socket called Socket AM2 for easy CPU installation. W hen 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.

For the latest information about CPU, please visit http://www.msi.com.tw/program/ products/mainboard/mbd/pro_mbd_cpu_support.php

Important

1.Overheating will seriously damage the CPU and system. Always make sure the cooling fan can work properly to protect the CPU from overheating.

2.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.

3.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.

2-3

MS-7325 Mainboard

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-de- gree 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 proc edures 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.

Installing AMD Socket AM2 CPU Cooler Set

W hen 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 CPUs 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 .

Fixed Lever

3. Fasten down the lever.

4.Attach the CPU Fan cable to the CPU fan connector on the mainboard.

Memory

The mainboard provides four 240-pin non-ECC DDRII DIMMs and supports up to 8GB system memory.

Hardware Setup

Installing DDRII 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.

Important

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

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

Volt Notch

Important

-DDRII modules are not interchangeable with DDR and the DDRII standard is not backwards compatible. You should always install DDRII memory modules in the DDRII DIMMs and DDR memory modules in the DDR DIMMs.

-In dual-channel mode, make sure that you install memory modules of the

same type and density in different channel DDR DIMMs.

-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.

Power Supply

ATX 24-Pin Power Connector: JPWR1

This connector allows you to connect an ATX 24-pin power supply. To connect the ATX 24-pin power supply, make sure the plug of the power supply is inserted in the proper orientation and the pins are aligned. Then push down the power supply firmly into the connector.

You may use the 20-pin ATX power supply as you like. If you’d like to use the 20-pin ATX power supply, please plug your power supply along with pin 1 & pin 13 (refer to the image at the right hand). There is also a foolproof design on pin 11, 12, 23 & 24 to avoid wrong installation.

Hardware Setup

Important Notification about Power Issue

NForce chipset is very sensitive to ESD (Electrostatic Discharge), therefore this issue mostly happens while the users intensively swap memory modules under S5 (power-off) states, and the power code is plugged while installing modules. Due to several pins are very sensitive to ESD, so this kind of memory-replacement actions might cause system chipset unable to boot. Please follow the following solution to avoid this situation.

Unplug the AC power cable (shown in figure 1) or unplug the JPWR1/ PCIE_PW1 & JPW1 power connectors (shown in figure 2 & figure 3) before the 1st installation or during system upgrade procedure.

ATA133 Hard Disk Connectors: IDE1/ IDE2

The mainboard has a 32-bit Enhanced PCI IDE and Ultra DMA 66/100/133 controller that provides PIO mode 0~4, Bus Master, and Ultra DMA 66/ 100/133 function. You can connect hard disk drives, CD-ROM and other IDE devices.

The Ultra ATA133 interface boosts data transfer rates between the computer and the hard drive up to 133 megabytes (MB) per second. The new interface is one-third faster than earlier record-breaking Ultra ATA/ 100 technology and is backwards compatible with the existing Ultra ATA interface.

IDE1 (Primary IDE Connector)

The first hard drive should always be connected to IDE1. IDE1 can connect a Master and a Slave drive. You must configure the second hard drive to Slave mode by setting the jumper accordingly.

IDE2 (Secondary IDE Connector)

IDE2 can also connect a Master and a Slave drive.

Important

If you install two hard disks on IDE cable, you must configure the second drive to Slave mode by setting its jumper. Refer to the hard disk documentation supplied by hard disk vendors for jumper setting instructions.
