AMD Athlon™ / Duron™ Processor Family
Cooling Solutions
As processor technology pushes to faster speeds and higher performance, thermal
management becomes increasingly crucial when building computer systems.
Maintaining the proper thermal environment is key to reliable, long-term system
operation. The overall goal in providing the proper thermal environment is keeping
the processor below its specified maximum case temperature. Heatsinks induce
improved processor heat dissipation through increased surface area and concentrated
airflow from attached fans. In addition, interface materials allow effective transfers
of heat from the processor to the heatsink. For optimum heat transfer, AMD
recommends the use of thermal grease and mounting clips to attach the heatsink to
the processor.
When selecting a thermal solution for your system, please refer to the website below
for collection of heatsinks evaluated and recommended by AMD for use with AMD
processors. Note, those heatsinks are recommended for maintaining the specified
Maximum T case requirement. In addition, this collection is not intended to be a
comprehensive listing of all heatsinks that support AMD processors.

Introduction of V333U Motherboard
1-1 Feature of motherboard
The V333U motherboard is design for use AMD Athlon/Duron/Athlon XP 200MHz
/266MHz (Double Data Rate) Front Side Bus Frequency CPU, which utilize the
Socket-A design and the memory size expandable to 3.0GB.
This motherboard use the newest VIA KT333 chipset, whose 133MHz/266MHz
(Double Data Rate) Front Side Bus frequency and 333MHz memory interface
delivers a clear upgrade path to the future generation of 266MHz processors and
DDR200/DDR266/DDR333 DDR SDRAM. The V333U motherboard offers ULTRA
ATA 133 to provide speedier HDD throughout that boosts overall system
performance.
These motherboards also has an integrated AC’97 2.1 CODEC on board which is
fully compatible with Sound Blaster Prothat gives you the best sound quality and
compatibility. It Supports 4 channel Speaker for 3D Surround Effect.
For those wanting even greater graphic performance, an AGP 4X slot is included on
the board.
With USB control as well as capability of expanding to 6 USB function ports support
USB2.0/USB1.1 Devices, the V333U meet future USB demand also this motherboard
has built-in hardware monitor function. This will monitor and protect your
computer.
A special design in hardware for protecting Athlon XP CPU from burned, the
system will auto shutdown power supply when CPU is overheat or the CPU FAN is
stop.
In V333U we design in CPU Vcore Voltage, DDR memory 2.5V Voltage, AGP
1.5V Voltage those can minor adjustable in BIOS setup. This design can let users
approach over clock demand and also can make system more stable. The V333U
motherboard provides special function in BIOS Setup to setting CPU Host clock step
by step increasing let users to approach over clocking, and special design in
hardware to protect BIOS from virus crash BIOS data.
V333U provides high performance & meets future specification demand. It is really
wise choice for your computer.

2-3-2 About AMD Athlon & Duron 462-pin CPU
This motherboard supports Socket-A (Socket-462) AMD Athlon/Duron processors.
This motherboard Provides a ZIF Socket-A. The CPU that comes with the motherboard
should have a cooling FAN attached to prevent overheating. If this is not the case, then
purchase a correct cooling FAN before you turn on your system.
WARNING! Be sure that there is sufficient air circulation across the processor’s heatsink
and CPU cooling FAN is working correctly, otherwise it may cause the
processor and motherboard overheat and damage, you may install an
auxiliary cooling FAN, if necessary.
WARNING! Due to this motherboard provides new function of protecting CPU；you
must connect the CPU FAN connector on FAN1 location in order to obtain
this feature. Without connection on FAN1 (or you have connect CPU FAN
on FAN2), the system will shut down immediately to protect both your CPU
and motherboard.
Over heat Protect: Only for Athlon XP serial CPU, when the CPU overheat, system will
auto shut down power supply. You can hear a continue beep sound, the
power button will be locked up. Users must turn off and turn on the AC
power to reset the system otherwise the power button will no function,
the other way is keeping press the push button few seconds till the beep
sound stop, then release the power button and press the power button
again to turn on the power supply.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF socket
and open it by first pulling the level sideways away from the socket then upward to a 90-
degree angle. Insert the CPU with the correct orientation as shown below. The notched
corner should point toward the end of the level. Because the CPU has a corner pin for two
of the four corners, the CPU will only fit in the orientation as shown.

When you put the CPU into the ZIF socket. No force require to insert of the CPU, then
press the level to Locate position slightly without any extra force.

2-4 Install Memory
This motherboard provides three 184-pin DUAL INLINE MEMORY MODULES (DIMM)
sites for memory expansion available from minimum memory size of 64MB to maximum
memory size of 3.0GB DDR SDRAM.
Valid Memory Configurations
Bank 184-Pin DIMM Total Memory
Bank 0, 1 (DDR1) PC1600/PC2100/PC2700 DDR SDRAM X1 64MB∼1.0GB
Bank 2, 3 (DDR2) PC1600/PC2100/PC2700 DDR SDRAM X1 64MB∼1.0GB
Bank 4, 5 (DDR3) PC1600/PC2100/PC2700 DDR SDRAM X1 64MB∼1.0GB
Total System Memory (Max. 3.0GB) 3 64MB∼3.0GB
NOTE! Make sure the total installed memory does not exceeds 3.0GB, otherwise the
system may hang during startup.
Generally, installing DDR SDRAM modules to your motherboard is very easy, you can
refer to figure 2-4 to see what a 184-Pin PC1600/PC2100/PC2700 DDR SDRAM module
looks like.
DDR2 (BANK2+BANK3) DDR1 (BANK0+BANK1) DDR3 (BANK4+BANK5)
NOTE! When you install DIMM module fully into the DIMM socket the eject tab
should be locked into the DIMM module very firmly and fit into its
indention on both sides.
WARNING! For the DDR SDRAM CLOCK is set at 166MHz, use only PC2700-
compliant DDR Modules. When this motherboard operate at 133Mhz,
most system will not even boot if non-compliant modules are used because
of the strict timing issues, if your DDR Modules are not PC2100-
compliant, set the DDR SDRAM clock to 100MHz to ensure system
stability.

2-5 Expansion Cards
WARNING! Turn off your power when adding or removing expansion cards or other
system components. Failure to do so may cause severe damage to both
your motherboard and expansion cards.
2-5-1 Procedure For Expansion Card Installation
1. Read the documentation for your expansion card and make any necessary hardware or
software setting for your expansion card such as jumpers.
2. Remove your computer’s cover and the bracket plate on the slot you intend to use.
3. Align the card’s connectors and press firmly.
4. Secure the card on the slot with the screen you remove above.
5. Replace the computer system’s cover.
6. Set up the BIOS if necessary.
7. Install the necessary software driver for your expansion card.
2-5-2 Assigning IRQs For Expansion Card
Some expansion cards need an IRQ to operate. Generally, an IRQ must exclusively assign
to one use. In a standard design, there are 16 IRQs available but most of them are already
in use.
Standard Interrupt Assignments
IRQ Priority Standard function
0 N/A System Timer
1 N/A Keyboard Controller
2 N/A Programmable Interrupt
3 * 8 Communications Port (COM2)
4 * 9 Communications Port (COM1)
5 * 6 Sound Card (sometimes LPT2)
6 * 11 Floppy Disk Controller
7 * 7 Printer Port (LPT1)
8 N/A System CMOS/Real Time Clock
9 * 10 ACPI Mode when enabled
10 * 3 IRQ Holder for PCI Steering
11 * 2 IRQ Holder for PCI Steering
12 * 4 PS/2 Compatible Mouse Port

IMPORTANT! If using PCI cards on shared slots, make sure that the drivers support
“Shared IRQ” or that the cards don’t need IRQ assignments. Conflicts
will arise between the two PCI groups that will make the system
unstable or cards inoperable.

ATX Power Supply connector. This is a new defined 20-pins connector that usually
comes with ATX case. The ATX Power Supply allows to use soft power on
momentary switch that connect from the front panel switch to 2-pins Power On
jumper pole on the motherboard. When the power switch on the back of the ATX
power supply turned on, the full power will not come into the system board until the
front panel switch is momentarily pressed. Press this switch again will turn off the
power to the system board.
