Introduction to DDR SDRAM
DDR (Double Data Rate) SDRAM is similar to conventional SDRAM, but
doubles the rate by transferring data twice per cycle. It uses 2.5 volts as opposed
to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM modules rather
than 168-pin DIMM modules used by SDR SDRAM.
MSI Reminds You...
For Micron MT46V32M8TG-5B DDR400 memory module,
please be sure to install 2 dimms to avoid the incompatibility
issue.

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.
Clear ESCD
The ESCD (Extended System Configuration Data) NVRAM (Non-volatile
Random Access Memory) is where the BIOS stores resource information for
both PNP and non-PNP devices in a bit string format. When the item is set to
Enabled, the system will reset ESCD NVRAM right after the system is booted
up and then set the setting of the item back to Disabled automatically. Settings:
Disabled, Enabled.
Resources Controlled By
The Award Plug and Play BIOS has the capacity to automatically configure all
of the boot and Plug and Play compatible devices. However, this capability
means absolutely nothing unless you are using a Plug and Play operating
system such as Windows® 98/2000. If you set this field to “manual”, choose
specific resources by going into each sub-menu that follows this field. Settings:
Auto(ESCD), Manual.
3-23
MS-6540G Micro ATX Mainboard
IRQ Resources
The items are adjustable only when Resources Controlled By is set to Manual.
Press <Enter> and you will enter the sub-menu of the items.
IRQ Resources list IRQ 3/4/5/7/9/10/11/12/14/15 for users to set each IRQ a
type depending on the type of device using the IRQ. Settings are:
PCI Device
For Plug & Play compatible devices designed for PCI
bus architecture.
Reserved
The IRQ will be reserved for further request.
PCI/VGA Palette Snoop
When set to Enabled, multiple VGA devices operating on different buses can
handle data from the CPU on each set of palette registers on every video
device. Bit 5 of the command register in the PCI device configuration space is
the VGA Palette Snoop bit (0 is disabled). For example, if there are two VGA
devices in the computer (one PCI and one ISA) and the:
VGA Palette
Snoop Bit Setting
Action
Disabled
Data read or written by the CPU is only directed to the PCI
VGA device’s palette registers.
Enabled
Data read or written by the CPU is directed to both the PCI
VGA device’s palette registers and the ISA VGA device’s
palette registers, permitting the palette registers of both VGA
devices to be identical.
The setting must be set to Enabled if any ISA bus adapter in the system
requires VGA palette snooping.

PC Health Status
This section shows the status of your CPU, fan, overall system status, etc.
Monitor function is available only if there is hardware monitoring mechanism
onboard.
Smart Fan Target Temp. (oC)
W83627THF provides the Smart Fan system which can control the fan speed
automatically depending on the current temperature to keep it with in a specific
range.
Smart Fan Temp. Tolerance
You can select a fan tolerance value here for the specific range for the “Smart
Fan Target Temp. (oC)” item. If the current temperature of the fan reaches to the
maximum threshold (the temperature set in the “Smart Fan Target Temp.(oC)”
plus the tolerance values you set here), the fan will speed up for cooling down.
On the contrary, if the current temperature reaches to the minimum threshold
(the set temperature minus the tolerance value), the fan will slow down to keep
the temperature stable.
Case Open Warning
The field enables or disables the feature of recording the chassis intrusion
status and issuing a warning message if the chassis is once opened. This item
is available only when your mainboard has JCI1 jumper. To clear the warning
message, set the field to Reset. The setting of the field will automatically return

CPU Clock Ratio
End users can overclock the processor (only if the processor supports so) by
specifying the CPU ratio (clock multiplier) in this field. It is available only when
“Set CPU Ratio” is set to Manual.
AutoDetect DIMM/PCI Clk
This item is used to auto detect the PCI slots. When set to Enabled, the
system will remove (turn off) clocks from empty PCI slots to minimize the
electromagnetic interference (EMI). Settings: Enabled, Disabled.
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 Disabled for optimal system stability and
performance. But if you are plagued by EMI, set 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 clock speed which may just
cause your overclocked processor to lock up.
CPU Frequency
Use this item to select the appropriate clock frequency of the CPU host bus.
Options are: 100MHz, 133MHz, 200MHz, Default.

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 <Enter>. You may also press <Esc> to abort the selection and not
enter a password.
To clear a set password, just press <Enter> 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 BIOS 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 Security Option of the Advanced BIOS Feature menu. If the
Security Option is set to System, 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.
