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 16GB) 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 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/ 3 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.

Chassis Intrusion

The field enables or disables the feature of recording the chassis intrusion status
and issuing a warning message if the chassis is once opened. To clear the warning
message, set the field to [Reset]. The setting of the field will automatically return to
[Enabled] later.

CPU Smart FAN Target

The mainboard provides the Smart Fan function which can control the CPU fan speed
automatically depending on the current temperature to keep it with in a specific range.
You can select a fan target value here. If the current CPU fan temperature reaches to
the target value, the smart fan function will be activated. It provides several sections
to speed up for cooling down automaticlly.

Current CPU/ FSB/ DRAM Frequency

These items show the current clocks of CPU and Memory speed. Read-only.

D.O.T Control

D.O.T. (Dynamic Overclocking Technology) is the automatic overclocking function,
included in the MSITM’s newly developed CoreCell
detect the load balance of CPU while running programs, and to adjust the best CPU
frequency automatically. When the motherboard detects CPU is running programs, it
will speed up CPU automatically to make the program run smoothly and faster. When
the CPU is temporarily suspending or staying in the low load balance, it will restore
the default settings instead. Usually the Dynamic Overclocking Technology will be
powered only when users' PC need to run huge amount of data like 3D games or the
video process, and the CPU frequency need to be boosted up to enhance the overall
performance. Settings are:

[Disabled] Disable Dynamic Overclocking.
[Private] 1st level of overclocking, increasing the frequency by 1%.

Technology. It is designed to

3-21

MS-7350 Mainboard

[Sergeant] 2nd level of overclocking, increasing the frequency by 3%.
[Captain] 3rd level of overclocking, increasing the frequency by 5%.
[Colonel] 4th level of overclocking, increasing the frequency by 7%.
[General] 5th level of overclocking, increasing the frequency by 10%.
[Commander] 6th level of overclocking, increasing the frequency by 15%.

Important

Even though the Dynamic Overclocking Technology is more stable than
manual overclocking, basically, it is still risky. We suggest user to make
sure that your CPU can afford to overclocking regularly first. If you find the
PC appears to be unstable or reboot incidentally, it's better to disable the
Dynamic Overclocking or to lower the level of overclocking options. By the
way, if you need to conduct overclocking manually, you also need to disable
the Dynamic OverClocking first.

controls the number of cycles for Row Address Strobe (RAS) to be allowed to
precharge. If insufficient time is allowed for the RAS to accumulate its charge
before DRAM refresh, refreshing may be incomplete and DRAM may fail to retain
data. This item applies only when synchronous DRAM is installed in the system.

tRAS

When the Memory Timings sets to [Manual], the field is adjustable. This setting
determines the time RAS takes to read from and write to a memory cell.

tRRD

When the Memory Timings sets to [Manual], the field is adjustable. Specifies
the active-to-active delay of different banks.

tRC

When the Memory Timings sets to [Manual], the field is adjustable. The row
cycle time determines the minimum number of clock cycles a memory row takes
to complete a full cycle, from row activation up to the precharging of the active
row.

bios section for details.)

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.B-7 for details.)

4. Initialize the NVRAID Array Disks.

Setting Up the NVRAID BIOS

Be sure to enable the RAID mode for SATA devices 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
Utility --- Define a New Array win­dow will appear.
The default RAID Mode is set to
Mirroring and Striping Block is
set to Optimal.

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 Controller 1, Channel
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)

3.0.M Controller 3, Channel 0, Master (SATA5)

3.1.M Controller 3, Channel 1, Master (SATA6)

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.

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

By default, this is set to [Mirroring]. To change to a different RAID mode, press the
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

arrow key (-->). The first disk in the list is moved, and the next disk in the list is
selected and ready to be moved.

3. Continue pressing the right-arrow key (<-- ) until all the disks that you want to use

as RAID array disks appear in the Array Disks block.

It shows that two disks have been assigned as RAID1 array disks in the figure
above.

Completing the RAID BIOS Setup

1.After assigning your RAID array disks, press F7. The Clear disk data prompt
appears.

2.Press Y if you want to wipe out all the data from the RAID array, otherwise press
N. You must choose Yes if the drives were previously used as RAID drives.
The Array List window appears, where you can review the RAID arrays that you
have set up.

3. Use the arrow keys to select the array that you want to set up, then press Enter.
The Array Detail window appears.

4. If you want to mark this disk as empty and wipe out all its contents then press C.

5. At the prompt, press Y to wipe out all the data, otherwise press N.

6.Press Enter again to go back to the previous window and then press Ctrl+X to
exit the RAID setup. Now that the RAID setup has been configured from the RAID
BIOS, the next step is to configure and load NVRAID drivers under Windows, as
explained in “Installing the NVIDIA RAID Software Under Windows” on p.B-9.

4.Press Enter to continue with Windows XP Installation. Be sure to leave the floppy
disk inserted in the floppy drive until the blue screen portion of Windows XP
installation is completed, then take out the floppy.

5.Follow the instructions on how to install Windows XP. After Windows XP is com­pletely installed, it is recommended that you install the the RAID management tool.

Important

Each time you add a new hard drive to a RAID array, the RAID driver will have
to be installed under Windows once for that hard drive. After that, the driver
will not have to be installed.

NVIDIA RAID Utility Installation

Installing the NVIDIA RAID Software Under Windows
(for Non-bootable RAID Array)

The existing Windows IDE Parallel ATA driver (as well as the Serial ATA driver if SATA
is enabled) must be upgraded to use the NVIDIA IDE Parallel ATA driver (as well as the
NV Serial ATA driver if SATA is enabled).
This section describes how to run the setup application and install the RAID software
which will upgrade the Windows IDE driver and install the RAID software.
