Hardware Setup

CPU (Central Processing Unit)

The mainboard supports AMD® Athlon64 X2/ Athlon64 & Athlon FX processors. The
mainboard uses a CPU socket called Socket AM2(940-pin) for easy CPU installation.
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.
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.

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.

Sliding

Plate

90 degree

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.

Hardware Setup

Installing AMD Socket AM2 CPU Cooler Set

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 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.

3.Fasten down the lever.

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

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

* 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.

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 differentchannel 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 8 GB) when each DIMM is installed with a 2GB
memory module.

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 & JPW1 power
connectors (shown in figure 2 & figure 3) before the 1st installation or during system
upgrade procedure.

PNP/PCI Configurations

This section describes configuring the PCI bus system and PnP (Plug & Play) feature.
PCI, or Peripheral Component Interconnect, is a system which allows I/O devices to
operate at speeds nearing the speed the CPU itself uses when communicating with
its special components. This section covers some very technical items and it is
strongly recommended that only experienced users should make any changes to the
default settings.

Primary Graphics Adapter

This setting specifies which graphics card is your primary graphics adapter.

PCI Latency Timer

This item controls how long each PCI device can hold the bus before another takes
over. When set to higher values, every PCI device can conduct transactions for a
longer time and thus improve the effective PCI bandwidth. For better PCI performance,
you should set the item to higher values.

PCI Slot 1/2 IRQ

These items specify the IRQ line for each PCI slot.

3-18

BIOS Setup

IRQ Resource Setup

Press <Enter> to enter the sub-menu and the following screen appears.

IRQ 3/4/5/7/9/10/11/14/15

These items specify the bus where the specified IRQ line is used.
The settings determine if AMIBIOS should remove an IRQ from the pool of avail­able IRQs passed to devices that are configurable by the system BIOS. The
available IRQ pool is determined by reading the ESCD NVRAM. If more IRQs must
be removed from the IRQ pool, the end user can use these settings to reserve
the IRQ by assigning an [Reserved] setting to it. Onboard I/O is configured by
AMIBIOS. All IRQs used by onboard I/O are configured as [Available]. If all IRQs
are set to [Reserved], and IRQ 14/15 are allocated to the onboard PCI IDE, IRQ 9
will still be available for PCI and PnP devices.

Important

IRQ (Interrupt Request) lines are system resources allocated to I/O devices.
When an I/O device needs to gain attention of the operating system, it sig­nals this by causing an IRQ to occur. After receiving the signal, when the
operating system is ready, the system will interrupt itself and perform the
service required by the I/O device.

DMA Resource Setup

Press <Enter> to enter the sub-menu and the following screen appears.

DMA Channel 0/1/3/5/6/7

The settings determine if AMIBIOS should remove a DMA (Direct Memory Access)
from the available DMAs passed to devices that are configurable by the system
BIOS. The available DMA pool is determined by reading the ESCD NVRAM. If more
DMAs must be removed from the pool, the end user can reserve the DMA.

nVidia RAID

NVIDIA brings Redundant Array of Independent Disks
(RAID) technology—which is used by the world’s lead­ing businesses—to the common PC desktop. This tech­nology uses multiple drives to either increase total disk
space or to offer data protection. For all levels, RAID
techniques optimize storage solutions by using multiple
disks grouped together and treating them as a single
storage resource.

Introduction

System Requirement

Operating System Support

NVRAID supports the following operating systems:

Windows XP/ 2000

RAID Arrays

NVRAID supports the following types of RAID arrays described in this section:
RAID 0: RAID 0 defines a disk striping scheme that improves the disk read and write
times for many applications.
RAID 1: RAID 1 defines techniques for mirroring data.
RAID 0+1: RAID 0+1 combines the techniques used in RAID 0 and RAID 1 arrays.
RAID 5: RAID 5 defines techniques for parity data.
Spanning (JBOD): JBOD provides a method for combining drives of different sizes
into one large disk

RAID Configuration

Basic Configuration Instructions

The following are the basic steps for configuring NVRAID:

Non-Bootable RAID Array

1. Choose the hard disks that are to be RAID enabled in the system BIOS. (To enable

the SATA 0/ 1 Primary/ Secondary Channel in On-Chip ATA Devices of Inte-
grated Peripherals in BIOS.)

2. Specify the RAID level, either Mirroring (RAID 1), Striping (RAID 0), Striping and

Mirroring (RAID 0+1), RAID 5 or JBOD and create the desired RAID array.

3. Enter the Windows OS, run the Windows nForce Setup application and install the

RAID software. (Check p. C-9 for details.)

4. Initialize the NVRAID Array Disks.

Bootable RAID Array

1. Choose the hard disks that are to be RAID enabled in the system BIOS. (To enable

the SATA 0/ 1 Primary/ Secondary Channel in On-Chip ATA Devices of Inte-
grated Peripherals in BIOS.)

2. Specify the RAID level, either Mirroring (RAID 1), Striping (RAID 0), Striping and

Mirroring (RAID 0+1), RAID 5 or JBOD and create the desired RAID array.

3. Boot from the Windows CD, use the floppy disk that has the RAID driver to copy

and install the nForce RAID software. (Check p.C-7 for details.)

4. Initialize the NVRAID Array Disks.

Setting Up the NVRAID BIOS

Be sure to enable the SATA 0/ 1 Primary/ Secondary Channel in On-Chip ATA
Device of Integrated Peripherals in BIOS before configuring the NVRAID BIOS.

After that press F10 to save the configuration and exit. The PC will reboot right away.
Then enter the RAID BIOS Setup by pressing F10 when prompted, and follow the
procedures described below to set up the NVRAID BIOS.
NVRAID BIOS setup lets you choose the RAID array type and which hard drives you
want to make part of the array.

Entering the RAID BIOS Setup

1. After rebooting your PC, wait until you
see the RAID software prompting you
to press F10. The RAID prompt ap­pears as part of the system POST and
boot process prior to loading the OS.

2. Press F10, and the NVIDIA RAID Util-
ity --- Define a New Array window
will appear.
The default RAID Mode is set to Mir-

roring and Striping Block is set to
Optimal.

C-3

MS-7252 Mainboard

Understanding the “Define a New Array ” Window

Use the Define a New Array window to

• Select the RAID Mode

• Set up the Striping Block

• Specify which disks to use for the RAID Array

Depending on the platform used, the system can have one or more channels. In a
typical system there is usually one controller and multiple channels, and each chan­nel has a slave and a master.
The channel/controller/master/slave status of each hard disk is given in the Loc
(location) columns of the Free Disks and Array Disks lists.

In the example above, 1.0.M means the hard drive is attached to Channel 2, Controller
0, and the drive is set to Master. The following is a list of all possible combinations:

Serial ATA

1.0.M Controller 1, Channel 0, Master (SATA1)

1.1.M Controller 1, Channel 1, Master (SATA2)

2.0.M Controller 2, Channel 0, Master (SATA3)

2.1.M Controller 2, Channel 1, Master (SATA4)

Important

There is no such thing as Slave drive in Serial ATA. All drives are considered
to be Master since there is a one to one connection between the drive and the
controller.

C-4

nVidia RAID

Using the Define a New Array Window

If necessary, press the tab key to move from field to field until the appropriate field is
highlighted.

• Selecting the RAID Mode

down arrow key until the mode that you want appears in the RAID Mode box—either
[Mirroring], [Striping], [RAID5], [Spanning], or [Stripe Mirroring].

• Selecting the Striping Block Size

Striping Block size is given in kilobytes, and affects how data is arranged on the

disk. It is recommended to leave this value at the default [Optimal], which is 32KB, but
the values can be between [4 KB] and [128 KB].

• Assigning the Disks

The disks that you enabled from the RAID Config BIOS setup page appear in the Free
Disks block. These are the drives that are available for use as RAID array disks.

To designate a free disk to be used as a RAID array disk,

1. Tab to the Free Disks section. The first disk in the list is selected.

2. Move it from the Free Disks block to the Array Disks block by pressing the right
