BIOS Setup
Onboard Serial Port A/B
These items specify the base I/O port addresses of the onboard Serial
Port 1 (COM A)/Serial Port 2 (COM B).  Selecting Auto allows AMIBIOS

This setting controls the operating mode of IR transmission/
reception. Setting options: Full Duplex, Half Duplex. Under Full
Duplex mode, synchronous, bi-directional transmission/reception
is allowed. Under Half Duplex mode, only asynchronous, bi-
directional transmission/reception is allowed.

The item selects the EPP version used by the parallel port if the port
is set to EPP mode. Settings: 1.7 and 1.9.
Parallel Port IRQ
When Onboard Parallel Port is set to Auto, the item shows Auto
indicating that BIOS determines the IRQ for the parallel port
automatically.

Parallel Port DMA Channel
This feature needs to be configured only when Parallel Port Mode is
set to the ECP mode. When Parallel Port is set to Auto, the field will
show Auto indicating that BIOS automatically determines the DMA
channel for the parallel port.

etc.  Monitor function is available only if there is hardware monitoring mecha-
nism onboard.
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

Use this menu to specify your settings for frequency/voltage control.
Dynamic OverClocking
Dynamic Overclocking Technology is the automatic overclocking function,
included in the MSI
TM’s newly developed CoreCellTM Technology. It is designed
to 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. Setting
options:
DisabledDisable Dynamic Overclocking.
Private1st level of overclocking.
Sergeant2nd level of overclocking.
Captain3rd level of overclocking, also the default value of Load
High Performance Defaults.
Colonel4th level of overclocking.
General5th level of overclocking.

BIOS Setup
Performance Mode
This item allows you to control the MAT (memory acceleration technology)
function of CPU. MAT is MSI
TM’s exclusive technology, specializing in opti-
mizing the data transfer rate among CPU, north bridge chip and memory, and
also in procuring better memory performance and bandwidth up to 10%. Se-
lecting Fast will enable MAT. Please be noted that not every memory is com-
patible with MAT. If the system fail to reboot for four times, the BIOS will be
restored to the Default value (Normal). Setting options: Normal, Fast.
CPU Ratio Selection
This setting controls the multiplier that is used to determine the internal clock
speed of the processor relative to the external or motherboard clock speed.
MSI Reminds You...
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, its better to disable the Dy-
namic 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.
MSI Reminds You...
1. Even though MAT is easy to use, it doesnt mean theres no
risk at all. We recommend you to check if your memory is
able to bear MAT setting or not before deciding to always
use it. If your system will be unstable or reboot incidentally
after switching to Fast, please switch back to Normal.
Moreover, if you want to conduct FSB overclocking, you
should set MAT as Normal.
2. Meanwhile, for security reason, there are two functions to
protect BIOS and protect user’s system from crashing:
( a ) There is a safe hotkey Ins in BIOS. If the overclocking
or/and MAT fails to run, you can press Ins key while
rebooting system to restore to the BIOS Defaults.
(b) If your system reboot for four times continually, the BIOS
    will be restored to the Defaults (Normal), too

DRAM  Frequency
Use this field to configure the clock frequency of the installed DRAM. Settings
are:  PSB 400:  266, Auto, 333, 400, 433, 466, 500.
 PSB 533:  266, 333, Auto, 400, 433, 450, 466, 500, 354 (3:4).
 PSB 800:  266, 333, 400, Auto, 433, 450, 466, 500, 532, 501 (4:5),
      533 (3:4).
Spread Spectrum
When the motherboard’s clock generator pulses, the extreme values (spikes)
of the pulses creates EMI (Electromagnetic Interference). The Spread Spec-
trum function reduces the EMI generated by modulating the pulses so that the
spikes of the pulses are reduced to flatter curves. 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, activate the Spread Spectrum for
EMI reduction. 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.  Options: Disabled,
Enabled.
Adjust CPU Bus Clock
This item allows you to select the CPU Bus clock frequency (in MHz) and
overclock the processor by adjusting the FSB clock to a higher frequency.
Settings are:  PSB 400:  100-355MHz.
 PSB 533:  133-500MHz
 PSB 800:  200-500MHz
DDR Clock (Mhz)
This read-only item allows you to view the current DDR clock.
Adjust AGP/PCI Clock (Mhz)
This item allows you to select the AGP/PCI clock frequency (in MHz) by
adjusting the AGP/PCI clock to a higher frequency.
CPU Vcore Adjust
The setting allows you to adjust the CPU Vcore voltage. Available options:
Yes, No.
MSI Reminds You...
The value plus a ratio (CPU: DDR) with parentheses means the
non-synchronous overclocking.

BIOS Setup
CPU Voltage (V)
The setting is adjustable if you set the “CPU Vcore Adjust” to “Ye s”.
DDR Power Voltage
Adjusting the DDR voltage can increase the DDR speed.  Any changes made
to this setting may cause a stability issue, so changing the DDR voltage for
long-term purpose is NOT recommended.
AGP Power Voltage
AGP voltage is adjustable in the field, allowing you to increase the performance
of your AGP display card when overclocking, but the stability may be affected.
MSI Reminds You...
Changing CPU Ratio/Vcore could result in the instability of the
system; therefore, it is NOT recommended to change the default
setting for long-term usage.
MSI Reminds You...
The settings shown in different color in CPU Voltage (V), DDR
Power Voltage and AGP Power Voltage helps to verify if your
setting is proper for your system.
White: Safe setting.
Yellow: High performance setting.
Red: Not recommended setting and the system may be unstable.
