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.

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.

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.

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.

3-16

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%.

TM

Technology. It is designed to

3-19

MS-7346 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.

System Clock Mode

This item is used to switch the following two items.

FSB Clock (MHz)

When the System Clock Mode sets to [Manual], the field is adjustable. This
item allows you to select the CPU Front Side Bus clock frequency (in MHz).

set this field to [Manual], the following fields will be selectable.

tCL (CAS Latency)

When the Memory Timings sets to [Manual], the field is adjustable.This con­trols the CAS latency, which determines the timing delay (in clock cycles) before
SDRAM starts a read command after receiving it.

tRCD

When DRAM is refreshed, both rows and columns are addressed separately.
This setup item allows you to determine the timing of the transition from RAS
(row address strobe) to CAS (column address strobe). The less the clock
cycles, the faster the DRAM performance.

3-20

BIOS Setup

tRP

When the Memory Timings sets to [Manual], the field is adjustable. This item
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.

tWR

When the Memory Timings sets to [Manual], the field is adjustable. Minimum
time interval between end of write data burst and the start of a precharge
command. Allows sense amplifiers to restore data to cells.

tWTR

When the Memory Timings sets to [Manual], the field is adjustable. Minimum
time interval between the end of write data burst and the start of a column-read
command. It allows I/O gating to overdrive sense amplifiers before read com­mand starts.

Important

1.If you do not have any EMI problem, leave the setting at [Disabled] for
optimal system stability and performance. But if you are plagued by EMI,
select the value of Spread Spectrum for EMI reduction.

2.The greater the Spread Spectrum value is, the greater the EMI is reduced,
and the system will become less stable. For the most suitable Spread
Spectrum value, please consult your local EMI regulation.

3.Remember to disable Spread Spectrum if you are overclocking because
even a slight jitter can introduce a temporary boost in clock speed which
may just cause your overclocked processor to lock up.

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/ 2 Primary/ Secondary Channel in nVidia RAID
Setup 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.

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)

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.
