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. High memory
bandwidth makes DDR an ideal solution for high performance PC, workstations and servers.

DIMM Module Combination
Install at least one DIMM module on the slots. You can install either
single- or double-sided modules to meet your own needs.
Intel® 82845G chipset supports a maximum of 4 memory banks. DIMM 1
alone occupies two memory banks; the other two banks are shared by DIMM2 & DIMM 3. Therefore, you must follow the table below to install memory

use, consult the vendor of your operating system. Options: 1.4, 1.1.
CPU L1 & L2 Cache
Cache memory is additional memory that is much faster than conventional
DRAM (system memory). When the CPU requests data, the system transfers
the requested data from the main DRAM into cache memory, for even faster
access by the CPU. The setting controls the L1 (also known as level 1 cache)
and L2 (also known as level 2 cache). Setting options: Disabled, WriteBack,WriteThru. WriteBack & WriteThru refer to the cache’s write policy, which
determines how it handles writes to memory locations that are currently being
held in cache. The WriteBack cache policy will produce the best performance.
Flash Protection
This function protects the BIOS from accidental corruption by unauthorized
users or computer viruses. When enabled, the BIOS’s data cannot be changed
when attempting to update the BIOS with a Flash utility. To successfully
update the BIOS, you’ll need to disable this BIOS Flash Write Control function.
You should enable this function at all times. The only time when you need to
disable the function is when you want to update the BIOS. After updating the
BIOS, you should immediately re-enable it to protect the BIOS against viruses.

Detect) EEPROM on the DRAM module. Setting to Enabled enables
CAS# Latency, RAS# Precharge, RAS# to CAS# Delay, Precharge Delay
and Burst Length automatically to be determined by BIOS based on the
configurations on the SPD. Selecting Disabled allows users to configure
these fields manually.
CAS# Latency
The field controls the CAS latency, which determines the timing delay before SDRAM starts a read command after receiving it. Setting
options: 2 Clocks and 3 Clocks. 2 Clocks increases system performance while 3Clocks provides more stable system performance.
RAS# Precharge
This item 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.
Available settings: 2 Clocks, 3 Clocks.
RAS# to CAS# Delay
This field allows you to set the number of cycles for a timing delay
between the CAS and RAS strobe signals, used when DRAM is
written to, read from or refreshed. Fast speed offers faster performance while slow speed offers more stable performance. Settings: 3Clocks, 2 Clocks.
Precharge Delay
The field specifies the idle cycles before precharging an idle bank.
Settings: 7 Clocks, 6 Clocks, 5 Clocks.
Burst Length
This setting allows you to set the size of Burst-Length for DRAM.
Bursting feature is a technique that DRAM itself predicts the
address of the next memory location to be accessed after the first
address is accessed. To use the feature, you need to define the
burst length, which is the actual length of burst plus the starting
address and allows internal address counter to properly generate

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 NVRAM
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 Yes,
the system will reset ESCD NVRAM right after the system is booted up and
then set the setting of the item back to No automatically.
PCI Latency Timer (PCI Clocks)
This item controls how long each PCI device can hold the bus before another
takes over. When set to higher values, every PCI device can conduct transactions for a longer time and thus improve the effective PCI bandwidth. For
better PCI performance, you should set the item to higher values. Settings
range from 32 to 248 at a 32 increment.
Init. Graphics Adapter Priority
This item specifies which VGA device is your primary graphics adapter. Set-

tings are:
Internal VGAThe system initializes the onboard VGA device.
AGP/Int-VGAThe system initializes the installed AGP card first. If
an AGP card is not available, it will initialize the
onboard VGA device.
AGP/PCIThe system initializes the installed AGP card first. If
an AGP card is not available, it will initialize the PCI
VGA card.
PCI/AGPThe system initializes the installed PCI VGA card first.
If a PCI VGA card is not available, it will initialize the
AGP card.
PCI/Int-VGAThe system initializes the installed PCI VGA card first.
If a PCI VGA card is not available, it will initialize the
onboard VGA device.
PCI IDE BusMaster
Set this option to Enabled to specify that the IDE controller on the PCI local
bus has bus mastering capability. Settings options: Disabled, Enabled.
These items specify the IRQ line for each PCI slot. Settings: 3, 4, 5, 7, 9, 10, 11,
Auto. Selecting Auto allows BIOS to automatically determine the IRQ line for
each PCI slot.
Set IRQs to PCI or ISA
Press <Enter> to enter the sub-menu and the following screen appears:
3-21
Page 67
Chapter 3
IRQ 3/4/5/7/9/10/11/14/15
These items specify the bus where the specified IRQ line is used.
The settings determine if AMIBIOS should remove an IRQ from the pool
of available IRQs passed to devices that are configurable by the system
BIOS. The available IRQ pool is determined by reading the ESCD NVRAM.
If more IRQs must be removed from the IRQ pool, the end user can use
these settings to reserve the IRQ by assigning an ISA/EISA setting to it.
Onboard I/O is configured by AMIBIOS. All IRQs used by onboard I/O
are configured as PCI/PnP. If all IRQs are set to ISA/EISA, and IRQ 14/
15 are allocated to the onboard PCI IDE, IRQ 9 will still be available for PCI
and PnP devices. Available settings: ISA/EISA, PCI/PnP.
Set DMAs to PnP or ISA
Press <Enter> to enter the sub-menu and the following screen appears:
DMA Channel 0/1/3/5/6/7
These items specify the bus that the system DMA (Direct Memory
Access) channel is used.
The settings determine if AMIBIOS should remove a DMA from the available DMAs passed to devices that are configurable by the system BIOS.
The available DMA pool is determined by reading the ESCD NVRAM. If
more DMAs must be removed from the pool, the end user can reserve the
DMA by assigning an ISA/EISA setting to it.

Frequency/Voltage Control
Use this menu to specify your settings for frequency/voltage control.
Spread Spectrum
When the motherboard 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, 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.
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.
CPU FSB Clock (Mhz)
This item allows you to select the CPU Front Side Bus clock frequency.
Setting options range from 100 to200. If you install a CPU other than
100MHz FSB, you should change the setting to corresponding FSB

frequency; otherwise, the CPU will run at the default configuration 100MHz.
The field also allows you to overclock the processor by adjusting the FSB
clock to a higher frequency.
CPU Vcore Adjust
This setting is used to enable or disable the ability to adjust CPU Vcore for
overclocking purpose. Setting options: Yes, No.
CPU Vcore
Specify preferred CPU core voltage (Vcore) in this field.
Note: Changing CPU Vcore could lead to a unstable system;
therefore, it is NOT recommended to change the default setting for
long-term usage.
DDR/AGP Power V oltage
Adjusting the DDR/AGP voltage can increase the DDR/AGP speed. Any
changes made to these settings may cause a stability issue, so changing theDDR/AGP voltage for long-term purpose is NOT recommended.

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 <Enter>. 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 <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 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 P ASSWORD CHECK option of the ADV ANCED 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.
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.

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 default 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.
The option is for power or overclocking users only. Use of high
WARNING!
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 highperformance 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 DA TA to
resolve the problem. For more information, refer to “Clear CMOS
Jumper:JBAT1” in Chapter 2.
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.
