Central Processing Unit: CPU
The mainboard supports Intel® Pentium® 4 Northwood/Prescott proces-
sor 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 find 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 = 100MHz
Core/Bus ratio = 20
then CPU core speed = Host Clock x Core/Bus ratio
= 100MHz x 20 = 2.0 GHz

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. Please note that the DDR SDRAM does not support ECC (error correcting code) and registered DIMM.
DDR Population Rules
Install at least one DIMM module on the slots. Each DIMM slot supports up to a maximum size of 1GB. Users can install either single- or double-sided modules to meet their own needs. Please note that each DIMM can work
respectively for single-channel DDR, but there are some rules while using dual-channel DDR (Please refer to the suggested DDR population table on p.
2-8). Users may install memory modules of different type and density on different-channel DDR DIMMs. However, the same type and density memory modules are necessary while using dual-channel DDR, or instability may happen.

MS-6728 ATX Mainboard
Please refer to the following table for detailed dual-channel DDR. Other combination not listed below will function as single-channel DDR.
DIMM1 (Ch A) DIMM2 (Ch A) DIMM3 (Ch B) DIMM4 (Ch B) System Density 128MB~1GB 128MB~1GB 256MB~2GB
128MB~1GB 128MB~1GB 256MB~2GB
128MB~1GB 128MB~1GB 128MB~1GB 128MB~1GB 512MB~4GB
MSI Reminds Y ou...
Dual-channel DDR works ONLY in the 3 combinations listed in the table above.
Installing DDR Modules
1. The DDR DIMM has only one notch on the center of module. The module
will only fit in the right orientation.
2. Insert the DIMM memory module vertically into the DIMM slot. Then
push it in until the golden finger on the memory module is deeply inserted in the socket.
MSI Reminds Y ou...
You can barely see the golden finger if the module is properly inserted in the socket.
3. The plastic clip at each side of the DIMM slot will automatically close.

(clocks) in creases the system per for mance th e most wh ile 3 (clocks) provides the most stable performance.
RAS# Precharge
Thi s 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, refreshing may be incomplete and DRAM ma y fail to retain data. This item applies only when synchronous DRAM is inst alled in the system. A vailable settings: 2 clocks, 3 clocks, 4 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: 2 clocks, 3 clocks, 4 clocks, .
Precharge Delay
This setting controls the precharge delay, which determines the timing delay for DRAM precharge. Settings: 5 clocks, 6 clocks, 7 clocks, 8 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. A vailable settings: 4, 8.
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 t he 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
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 Win­dow s 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 w ill 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.
PC I Latency Timer (PCI Clocks)
This item controls how long each PCI device can hold the bus before another ta kes over. When set to higher values, eve ry 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 are: 32, 64, 96, 128, 160, 192, 224, 248.

D.O.T. Range
(D.O.T) Dynamic Overclocking Technology is the automatic overclocking function, included in the MSITM’s new ly developed CoreCell
TM
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:
Disabled Disable Dynamic Overclocking. Private 1st level of overclocking. Sergeant 2nd level of overclocking. Capt ain 3rd level of overclocking, also the default value of "Load

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 overcloc king regularly first. If you find the PC appears to be unstable or reboot incidentally, it's better to disable the Dy­namic Over clocking 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.

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 stabil ity 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.
