							3-16MS-7528 Mainboard 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 automatically return to
[Enabled] later. CPU Smart FAN Target
The mainboard provides the Smart Fan function which can control the CPU fan speed
automatically depending on the current temperature to keep it with in a specific range.
You can select a fan target value here. If the current CPU fan temperature reaches to
the target value, the smart fan function will be activated. It provides several sections
to speed up for cooling down automaticlly. PC Health Status CPU/ System Temperature, CPU FAN/ SYS FAN1/ SYS FAN2 Speed, CPU
Vcore, 3.3V, 5V, 12V
These items display the current status of all of the monitored hardware devices/
components such as CPU voltage, temperatures and all fans’ speeds.H/W Monitor7528v1.0-3_BIOS.p65  2008/2/1, 下午 04:3016 
						

							3-17BIOS Setup Current CPU / DRAM Frequency
These items show the current clocks of CPU and Memory speed. Read-only. Intel EIST
The Enhanced Intel SpeedStep technology allows you to set the performance level of
the microprocessor whether the computer is running on battery or AC power. This
field will appear after you installed the CPU which support speedstep technology. Adjust CPU FSB Frequency
This item allows you to set the CPU FSB frequency (in MHz). Adjusted CPU Frequency
It shows the adjusted CPU frequency (FSB x Ratio). Read-only. Advance DRAM Configuration
Press  to enter the sub-menu. DRAM Timing Mode
Setting to [Enabled] enables DRAM CAS# Latency automatically to be determined
by BIOS based on the configurations on the SPD (Serial Presence Detect) EEPROM
on the DRAM module.Cell MenuImportant
Change these settings only if you are familiar with the chipset.7528v1.0-3_BIOS.p65  2008/2/1, 下午 04:3017 
						

							3-18MS-7528 Mainboard CAS Latency(CL)
When the DRAM Timing Mode sets to [Manual], the field is adjustable.This
controls the CAS latency, which determines the timing delay (in clock cycles)
before SDRAM starts a read command after receiving it.
Advance DRAM Configuration -> tRCD
When the DRAM Timing Mode sets to [Manual], the field is adjustable. When
DRAM is refreshed, both rows and columns are addressed separately. This
setup item allows you to determine the timing of the transition from RAS (row
address strobe) to CAS (column address strobe). The less the clock cycles, the
faster the DRAM performance.
Advance DRAM Configuration -> tRP
When the DRAM Timing Mode sets to [Manual], this field is adjustable. This
setting controls the number of cycles for Row Address Strobe (RAS) to be
allowed to precharge. If insufficient time is allowed for the RAS to accumulate its
charge before DRAM refresh, refresh may be incomplete and DRAM may fail to
retain data. This item applies only when synchronous DRAM is installed in the
system.
Advance DRAM Configuration -> tRAS
When the DRAM Timing Mode sets to [Manual], this setting determines the
time RAS takes to read from and write to a memory cell.
Advance DRAM Configuration -> tRTP
When the DRAM Timing Mode sets to [Manual], this setting controls the time
interval between a read and a precharge command.
Advance DRAM Configuration -> tRC
When the DRAM Timing Mode sets to [Manual], the field is adjustable. The row
cycle time determines the minimum number of clock cycles a memory row takes
to complete a full cycle, from row activation up to the precharging of the active
row.
Advance DRAM Configuration -> tWR
When the DRAM Timing Mode sets to [Manual], the field is adjustable. It speci-
fies the amount of delay (in clock cycles) that must elapse after the completion
of a valid write operation, before an active bank can be precharged. This delay
is required to guarantee that data in the write buffers can be written to the
memory cells before precharge occurs.
Advance DRAM Configuration -> tRRD
When the DRAM Timing Mode sets to [Manual], the field is adjustable. Speci-
fies the active-to-active delay of different banks.
Advance DRAM Configuration -> tWTR
When the DRAM Timing Mode sets to [Manual], the field is adjustable. This
item controls the Write Data In to Read Command Delay memory timing. This7528v1.0-3_BIOS.p65  2008/2/1, 下午 04:3018

constitutes the minimum number of clock cycles that must occur between the
last valid write operation and the next read command to the same internal bank
of the DDR device. Power User Mode
Press  to enter the sub-menu. ADJUST CHANNEL 0/1 DRIVE
These two Groups are used to program RCOMP buffer strengths and slew rate
table for the various signal groups of MCH. Each channel contains seven groups
of signal ( GROUP 0 ~ GROUP 6) ADJUST ODT Strength
This feature is designed to improve the signal integrity of the memory channel.
ODT(On-Die termination) allows a DRAM to adjust the termination resistance for
each DQ and DQS/DQS# signal. ADJUST SCOMP Strength
SCOMP (Secure Communications Processor) hardware protections against DMA
devices that allow it to move the corresponding device drivers from the base
layer to less critical parts of the system. FSB/Memory Ratio
This item will allow you to adjust the FSB/Ratio of the memory. Adjusted DRAM Frequency
It shows the adjusted DDR Memory frequency. Read-only. Adjust PCI-E Frequency(MHz)
This field allows you to select the PCIE frequency (in MHz). Auto Disable DIMM/PCI Frequency
When set to [Enabled], the system will remove (turn off) clocks from empty DIMM and
PCI slots to minimize the electromagnetic interference (EMI). 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. 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.7528v1.0-3_BIOS.p65  2008/2/1, 下午 04:3019 
						

							3-20MS-7528 Mainboard1.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.Important7528v1.0-3_BIOS.p65  2008/2/1, 下午 04:3020 
						

							3-21BIOS Setup
The two options on the main menu allow users to restore all of the BIOS settings to
the default Fail-Safe or Optimized values. The Optimized Defaults are the default
values set by the mainboard manufacturer specifically for optimal performance of the
mainboard. The Fail-Safe Defaults are the default values set by the BIOS vendor for
stable system performance.
When you select Load Fail-Safe Defaults, a message as below appears:
Pressing Y loads the BIOS default values for the most stable, minimal system
performance.
When you select Load Optimized Defaults, a message as below appears:
Pressing Y loads the default factory settings for optimal system performance.Load Fail-Safe/ Optimized Defaults7528v1.0-3_BIOS.p65  2008/2/1, 下午 04:3021 
						

							3-22MS-7528 MainboardBIOS Setting 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.7528v1.0-3_BIOS.p65  2008/2/1, 下午 04:3022
