D.O.T. Range
(D.O.T) Dynamic Overclocking Technology is the automatic overclocking
function, included in the MSITM
’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.
Commander6th level of overclocking.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.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 
						

							3-29 BIOS SetupD.O.T Mode
This item allows you to decide the mode to overclock dynamically. Setting
options: CPU Only, CPU+AGP.
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 (Mhz)
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 (Mhz)
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:  200-500MHzMSI Reminds You...
The value plus a ratio (CPU: DDR) with parentheses means the
non-synchronous overclocking. 
						

							3-30MS-6728 ATX Mainboard
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 (for Northwood CPU only)
The setting allows you to adjust the CPU Vcore voltage. Available options:
Yes, No.
CPU Voltage (V)  (for Northwood CPU only)
The setting is adjustable if you set the “CPU Vcore Adjust” to “Yes”.
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. 
						

							3-31 BIOS SetupSet 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 chang-
ing 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 pass-
word 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.MSI Reminds You...
About Supervisor Password & User Password:
Supervisor password:Can enter and change the settings of
the setup menu.
User password:Can only enter but do not have the
right to change the settings of the setup
menu. 
						

							3-32MS-6728 ATX MainboardLoad 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.
