Use this menu to specify your settings for frequency/voltage control.
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.
DRAM  Frequency
Use this field to configure the clock frequency of the installed DRAM. Settings
are: PSB 400:  266, Auto.
 PSB 533:  266, 333, Auto, 354.
 PSB 800:  266, 333, 400, Auto, 500, 532.
Spread Spectrum
When the motherboard’s clock generator pulses, the extreme values (spikes)
of the pulses creates 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.  If you do not have any EMI
problem, leave the setting at No for optimal system stability and performance.
But if you are plagued by EMI, setting to Enabled for EMI reduction.  Remember
to disable Spread Spectrum if you are overclocking because even a slight jitter
can introduce a temporary boost in clockspeed which may just cause your
overclocked processor to lock up.

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.

Set Supervisor/User Password
When you select this function, a message as below will appear on the
screen:
Type the password, up to six characters in length, and press .
The password typed now will replace any previously set password from CMOS
memory. You will be prompted to confirm the password. Retype the password
and press . You may also press  to abort the selection and not
enter a password.
To clear a set password, just press  when you are prompted to
enter the password. A message will show up confirming the password will be
disabled. Once the password is disabled, the system will boot and you can
enter Setup without entering any password.
When a password has been set, you will be prompted to enter  it every
time you try to enter Setup. This prevents an unauthorized person from changing
any part of your system configuration.
Additionally, when a password is enabled, you can also have AMIBIOS
to request a password each time the system is booted. This would prevent
unauthorized use of your computer. The setting to determine when the password
prompt is required is the PASSWORD CHECK option of the ADVANCED BIOS
FEATURES menu. If the PASSWORD CHECK option is set to Always, the
password is required both at boot and at entry to Setup. If set to Setup, password
prompt only occurs when you try to enter Setup.

BIOS Setup
Load High Performance/BIOS Setup Defaults
The two options on the main menu allow users to restore all of the BIOS
settings to High Performance defaults or BIOS Setup defaults. The High
Performance Defaults are the values set by the mainboard manufacturer for the
best system performance but probably will cause a stability issue. The BIOS
Setup Defaults are the default values also set by the mainboard manufacturer
for stable performance of the mainboard.
When you select Load High Performance Defaults, a message as below appears:
Pressing ‘Enter’ loads the default BIOS values that enable the best system
performance but may lead to a stability issue.
When you select Load BIOS Setup Defaults, a message as below appears:
Pressing ‘Enter’ loads the default values that are factory settings for stable
system performance.
MSI Reminds You...
The option is for power or overclocking users only. Use of high
performance defaults will tighten most timings to increase the
system performance. Therefore, a high-end system configuration
is a must, which means you need high-quality VGA adapter,
RAM and so on. We don’t recommend that users should apply
the high performance defaults in their regular systems.
Otherwise, the system may become unstable or even crash. If the
system crashes or hangs after enabling the feature, please CLEAR
CMOS DATA to resolve the problem. For more information, refer
to “Clear CMOS Jumper:JBAT1” in Chapter 2.
