Hardware Setup
Central Processing Unit: CPU
The mainboard supports Intel® Pentium® 4 processors in the 478 pin
package. The mainboard uses a CPU socket called PGA478 for easy CPU installation. When you are installing the CPU, make sure the CPU has a heat sink and a cooling fan attached on the top to prevent overheating. If you do not have the heat sink and cooling fan, contact your dealer to purchase and install them before turning on the computer.
CPU Core Speed Derivation Procedure
If CPU Clock = 200MHz
Core/Bus ratio = 12
then CPU core speed = Host Clock x Core/Bus ratio
= 200MHz x 12 = 2.4 GHz

Memory
The mainboard provides 2 slots for 184-pin, 2.5V DDR DIMM modules and supports the memory size up to 2 GB without ECC,. Y ou can install DDR266/ DDR333/DDR400 DDR SDRAM modules on the DDR DIMM slots. To operate properly, at least one DIMM module must be installed.
DIMM1-2
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. Three types of DDR are available at the time of writing: DDR266, DDR333 & DDR400. DDR266 DDR SDRAM running at 133MHz will produce about 1.6GB/s memory bandwidth. DDR333 running at 166MHz will produce 2.1GB/s memory bandwidth. DDR400 is also available with bandwidith up to 3.2GB/s for single­channel mode or with 6.4GB/s for dual-channel mode. High memory band­width makes DDR an ideal solution for high performance PC, workstations and servers.

BIOS Setup
increases the system performance the most while 3 (clocks) provides the most stable 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. A vailable settings: 2 clocks, 3 clocks.
RAS# to CAS# Delay
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. Setting options: 3 clocks, 2 clocks.
Precharge Delay
The field specifies the idle cycles before precharging an idle bank. Settings: 7, 6, 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 the next memory location. The bigger the size, the faster the DRAM performance.
Settings: 4 QW and 8 QW.
AGP Aperture Size (MB)
This setting controls just how much system RAM can be allocated to AGP for video purposes. The aperture is a portion of the PCI memory address range dedicated to graphics memory address space. Host cycles that hit the aperture range are forwarded to the AGP without any translation. The option allows the selection of an aperture size of 4MB, 8MB, 16MB, 32MB, 64MB, 128MB, and
256 MB.

Power Management Features
MSI Reminds Y ou...
S3-related functions described in this section are available only when your BIOS supports S3 sleep mode.
ACPI Standby State
This item specifies the power saving modes for ACPI function. If your operating system supports ACPI, such as Windows 98SE, Windows ME and Windows 2000, you can choose to enter the Standby mode in S1 (POS) or S3 (STR) fashion through the setting of this field. Options are:
S1/POS The S1 sleep mode is a low power state. In this state, no system
context is lost (CPU or chipset) and hardware maintains all system context.
S3/STR The S3 sleep mode is a lower power state where the information
of system configuration and open applications/files is saved to main memory that remains powered while most other hardware components turn off to save energy. The information stored in memory will be used to restore the system when a “wake up” event occurs.
Auto BIOS determines the best automatically.

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 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.

PCI IDE BusMaster
Set this option to Enabled to specify that the IDE controller on the PCI local bus has bus mastering capability. Setting options: Disabled, Enabled.
PCI Slot1/Slot4 IRQ Priority, PCI Slot2 IRQ Priority, PCI Slot3 IRQ Priority, PCI Slot5 IRQ Priority
These items specify the IRQ line for each PCI slot. Setting options: 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:
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.

Dynamic OverClocking
Dynamic Overclocking Technology is the automatic overclocking function, included in the MSITM’s newly developed CoreCell 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 T echnology 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:
Disabled Disable Dynamic Overclocking.

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, it's better to disable the Dy­namic 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.
Performance Mode
This item allows you to control the MAT (memory acceleration technology) function of CPU. MAT is MSITM’s exclusive technology, specializing in opti­mizing the data transfer rate among CPU, north bridge chip and memory, and also in procuring better memory performance and bandwidth up to 10%. Se­lecting Fast will enable MAT . Please be noted that not every memory is com­patible with MAT. If the system fail to reboot for four times, the BIOS will be restored to the Default value (Normal). Setting options: Normal, Fast.
MSI Reminds Y ou...
1. Even though MAT is easy to use, it doesn't mean there's no risk at all. We recommend you to check if your memory is able to bear MAT setting or not before deciding to always use it. If your system will be unstable or reboot incidentally after switching to Fast, please switch back to Normal. Moreover, if you want to conduct FSB overclocking, you should set MAT as Normal.
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

PSB 400: 100-355MHz. PSB 533: 133-500MHz PSB 800: 200-500MHz
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.
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. Also the setting you choose will change color for warning if the value is of over the specifications.
