Chapter 2

CPU Installation
The VIA P4MA PRO 533 mainboard supports the IntelPentium4 Willamette/ Northwood and Celeron processors in the 478 pin package (PGA478). When installing the CPU, ensure the CPU has a large-size heatsink and a cooling fan attached on the top to prevent overheating. If the heatsink and cooling fan are not included with the CPU, contact your dealer to purchase and install them before turning on the computer.

1. Pull the lever sideways away from the socket. Then raise the lever up to a 90-degree angle.
2. Look for the dot/cut edge. The dot/cut edge should point towards the lever pivot. The CPU will only fit in the correct orientation.
3. Hold the CPU down firmly, then close the lever shut to complete the installation.
Overheating will cause serious damage to the CPU and system. Ensure the cooling fan and heatsink work WARNING! properly to protect the CPU from overheating.
CPU Core Speed If then CPU Clock = Core / Bus ratio = CPU core speed = = = Overclocking
This mainboard is designed to support overclocking. However,
WARNING! please make sure your components are able to tolerate such abnor-

CPU Fan Installation

As processor technology pushes to faster speeds and higher performance, thermal management becomes increasingly important. To dissipate heat, you MUST attach the CPU cooling fan and heatsink on top of the CPU. Follow the instructions below to install the Heatsink/Fan:
1. Locate the CPU and its retention mechanism on the mainboard. Retention mechanism 2. Position the heatsink and fan onto the retention mechanism.
3. Mount the fan on top of the heatsink. Press down the fan firmly until its four clips become wedged in the holes of the retention mechanism.
4. Press the two levers down to secure the fan. Each lever can be pressed down in only ONE direction.
5. Connect the fan power cable from the mounted fan to the 3-pin fan power connector on the mainboard.

Memory Installation

The VIA P4MA PRO 533 mainboard provides 2 sockets for 184-pin, 2.5V DDR DIMM modules with 4 memory banks. To operate properly, at least one DIMM module must be installed. You can install PC1600/PC2100 DDR SDRAM modules on the DDR DIMM slots (DDR 1~2). DDR (Double Data Rate) SDRAM is similar to conventional SDRAM, but doubles the rate of transfer by transfering data twice per cycle. This is achieved by transfering data on both the rising and falling edges of the clock. Conventional SDRAM only uses the rising edge of the clock to transfer data. Therefore, conventional SDRAM is called SDR (Single Data Rate) SDRAM. DDR SDRAM uses 2.5 volts as opposed to 3.3 volts used in SDR SDRAM, and requires 184pin DIMM modules rather than 168-pin DIMM modules used by SDR SDRAM. DDR SDRAM is also known as SDRAM-II, DDR DRAM and DSDRAM (Double-Speed DRAM). PC2100 running at 133MHz will produce 2.1GB/s memory bandwidth. High memory bandwidth makes DDR an ideal solution for high performance PC, workstations and servers.

DDR DIMM Sockets (DDR 1~2)

DDR Module Installation

You can install either single sided or double sided 184-pin DDR DIMM modules into the DDR DIMM slot, depending on your requirements. Differing from SDR DIMM, DDR DIMM modules have only one notch on the center of the module. The number of pins on either side of the breaks are also different. The memory modules will only fit if placed in the correct orientation. You can install DDR SDRAM modules in any of the following combinations:
Slot Slot 1 (Bank 0 & Bank 1) Slot 2 (Bank 2 & Bank 3)
M emory M odule 64M B, 128MB, 256M B, 512MB, 1GB 64M B, 128MB, 256M B, 512MB, 1GB
Total M emory 64MB~1GB 64MB~1GB 64MB~2GB
M aximum System M emory Supported
1. The DDR DIMM module has only one notch on the center.
Notch 2. Insert the DDR module vertically into the DDR DIMM slot. Make sure the notch is correctly aligned.
3. The plastic clips at sides of the DIMM slot will automatically close shut.

Power Supply

Spread Spectrum

When the motherboards 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 problems, 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 0.25% jitter can introduce a temporary boost in clockspeed of 25MHz (with a 1GHz CPU) which may just cause your overclocked processor to lock up. Settings: Disabled, -
1.50%, -1.00%,-0.70%,-0.50%,+/-0.75%,+/-0.50%,+/-0.35% and+/0.25%.

Load Fail-Safe Defaults

This option on the main menu allows users to restore all the BIOS settings to the default Fail Safe values. These values are set by the mainboard manufacturer to provide the most stable system. When you select Load-Fail Safe Defaults, a message as below appears:
Pressing Y loads the default BIOS values that provide a minimal and stable system configuration.

Load Optimized Defaults

This option on the main menu allows users to restore all the BIOS settings to the default Optimized values. The Optimized Defaults are the default values also set by the mainboard manufacturer for both optimized and stable performance of the mainboard. When you select Load Optimized Defaults, a message as below appears:
Pressing Y loads the default values that are factory settings for optimal and stable system performance.
Set Supervisor/User Password
When you select this function, a message as below will appear on the screen:
Type the password, up to eight characters in length, and press <Enter>. The password typed now will clear any previously set password from CMOS memory. You will be prompted to confirm the password. Re-type 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 that 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 Features 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 trying to enter Setup.

Chapter 2

CPU Installation
The VIA P4MA mainboard supports the Intel Pentium 4 processor in the 478 pin package (PGA478). When installing the CPU, ensure the CPU has a largesize heatsink and a cooling fan attached on the top to prevent overheating. If the heatsink and cooling fan are not included with the CPU, contact your dealer to purchase and install them before turning on the computer.
1. Pull the lever sideways away from the socket. Then raise the lever up to a 90-degree angle.
2. Look for the dot/cut edge. The dot/cut edge should point towards the lever pivot. The CPU will only fit in the correct orientation.
3. Hold the CPU down firmly, then close the lever shut to complete the installation.
Overheating will cause serious damage to the CPU and system. Ensure the cooling fan and heatsink work WARNING! properly to protect the CPU from overheating.

CPU Core Speed

If then CPU Clock = Core/Bus ratio = CPU core speed = = = Overclocking
This mainboard is designed to support overclocking. However,
WARNING! please make sure your components are able to tolerate such abnor-
100MHz 18 CPU Clock x Core/Bus ratio 100MHz x 18 1.8GHz
mal settings, before overclocking. Any attempt to operate beyond product specifications is not recommended. We do not guarantee the damages or risks caused by inadequate operation or operation beyond

CPU Fan Installation

As processor technology pushes to faster speeds and higher performance, thermal management becomes increasingly important. To dissipate heat, you MUST attach the CPU cooling fan and heatsink on top of the CPU. Follow the instructions below to install the Heatsink/Fan:
1. Locate the CPU and its retention mechanism on the mainboard. Retention mechanism 2. Position the heatsink and fan onto the retention mechanism.
3. Mount the fan on top of the heatsink. Press down the fan firmly until its four clips become wedged in the holes of the retention mechanism.
4. Press the two levers down to secure the fan. Each lever can be pressed down in only ONE direction.

5. Connect the fan power cable from the mounted fan to the 3-pin fan power connector on the mainboard.

Memory Installation

The VIA P4MA mainboard provides 2 sockets for 184-pin, 2.5V DDR DIMM modules with 4 memory banks. To operate properly, at least one DIMM module must be installed. You can install PC1600/PC2100 DDR SDRAM modules on the DDR DIMM slots (DDR 1~2). DDR (Double Data Rate) SDRAM is similar to conventional SDRAM, but doubles the rate of transfer by transfering data twice per cycle. This is achieved by transfering data on both the rising and falling edges of the clock. Conventional SDRAM only uses the rising edge of the clock to transfer data. Therefore, conventional SDRAM is called SDR (Single Data Rate) SDRAM. DDR SDRAM 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. DDR SDRAM is also known as SDRAM-II, DDR DRAM and DSDRAM (Double-Speed DRAM). PC2100 running at 133MHz will produce 2.1GB/s memory bandwidth. High memory bandwidth makes DDR an ideal solution for high performance PC, workstations and servers.

DDR DIMM Slots (DDR 1~2)

DDR Module Installation
You can install either single sided or double sided 184-pin DDR DIMM modules into the DDR DIMM slot, depending on your requirements. Differing from SDR DIMM, DDR DIMM modules have only one notch on the center of the module. The number of pins on either side of the breaks are also different. The memory modules will only fit if placed in the correct orientation. You can install DDR SDRAM modules in any of the following combinations:
Slot Slot 1 (Bank 0 & Bank 1) Slot 2 (Bank 2 & Bank 3)
M emory M odule 64M B, 128MB, 256M B, 512M B, 1GB 64M B, 128MB, 256M B, 512M B, 1GB
Total M emory 64M B~1GB 64M B~1GB 64M B~2GB
M aximum System M emory Supported
1. The DDR DIMM module has only one notch on the center.
Notch 2. Insert the DDR module vertically into the DDR DIMM slot. Make sure the notch is correctly aligned.
3. The plastic clips at sides of the DIMM slot will automatically close shut.
