The mainboard supports AMD® Athlon64 / Athlon64 X2 / AM2+ processors in Socket
AM2/ AM2+. The Socket AM2/ AM2+ offers 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://global.msi.com.tw/index.
php?func=cpuform.
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.
Replacing the CPU
While replacing the CPU, always turn off the power supply or unplug the
power supply’s power cord from the grounded outlet first to ensure the safety
of CPU.

BIOS Setup
Power Management Setup
Important
S3-related functions described in this section are available only when your
BIOS supports S3 sleep mode.
ACPI Function
This item is to activate the ACPI (Advanced Configuration and Power Management
Interface) Function. If your operating system is ACPI-aware, such as Windows 98SE/
2000/ME/ XP, select [Enabled].
ACPI Standby State
This item specifies the power saving modes for ACPI function. If your operating
system supports ACPI, such as Windows 2000/XP, you can choose to enter the
Standby mode in S1(POS) or S3(STR) fashion through the setting of this field.
[S1]
The S1 sleep mode is a low power state. In this state, no
system context is lost (CPU or chipset) and hardware main-
tains all system context.
[S3]
The S3 sleep mode is a lower power state where the in
formation of system configuration and open applications/files
is saved to main memory that remains powered while most
other hardware components turn off to save energy. The
3-13
MS-7304 Mainboard
information stored in memory will be used to restore the sys-
tem when a “wake up” event occurs.
Re-Call VGA BIOS from S3
Selecting [Enabled] allows BIOS to call VGA BIOS to initialize the VGA card when
system wakes up (resumes) from S3 sleep state. The system resume time is short-
ened when you disable the function, but system will need an AGP driver to initialize
the VGA card. Therefore, if the AGP driver of the card does not support the initializa-
tion feature, the display may work abnormally or not function after resuming from S3.
Suspend Time Out (Minute)
If system activity is not detected for the length of time specified in this field, all
devices except CPU will be shut off.
Soft Off by PWR BTTN
When [Enabled], turning the system off with the on/off button places the system in a
very low-power-usage state, with only enough circuitry receiving power to detect
power button activity or Resume by Ring activity.
Restore on AC Power Loss
This item specifies whether your system will reboot after a power failure or interrupt
occurs.
[Off]
[On]
Always leaves the computer in the power off state.
Always leaves the computer in the power on state.
[Previous State] Restores the system to the status before power failure
or interrupt occurred.
Wakeup Event Setup
Resume From S3 By USB Device
The item allows the activity of the USB device to wake up the system from S3
(Suspend to RAM) sleep state.
Resume By PCI Device (PME#)
When set to [Enabled], the feature allows your system to be awakened from the
power saving modes through any event on PME (Power Management Event).
Resume By PCI-E Device
When set to [Enabled], the feature allows your system to be awakened from the
power saving modes through any event on PCIE device.

BIOS Setup
PNP/PCI Configurations
Primary Video Controller
This setting specifies which video controller 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
This setting specifies IRQs for PCI devices.
3-15
MS-7304 Mainboard
IRQ Resource Setup
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 avail-
able 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 sig-
nals 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.

Software Memory Hole
This field enables software to remap the physical memory to the address higher
than 00E0. (This item only works in 64-bit OS.)
Dual Channel Mode
In Dual-Channel mode, the memory modules can transmit and receive data with
two data bus lines simultaneously. Enabling Dual-Channel mode can enhance
the system performance.
DRAM Frequency
This setting allows users to adjust the memory frequency.
Spread Spectrum
When the motherboard’s clock generator pulses, the extreme values (spikes) of the
pulses create EMI (Electromagnetic Interference). The Spread Spectrum function
reduces the EMI generated by modulating the pulses so that the spikes of the pulses
are reduced to flatter curves.
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.
