Introduction
Chapter 1 Specification
This mainboard features an integration of the powerful AMD proces-
sors Athlon/Athlon XP/Duron and the North Bridge VIA Apollo KT400
plus South Bridge VT8235, with which the whole system performance
supports 333/266/200 MHz system bus.
VIA Apollo KT400 plus VT8235 supports on-board AMD processors
to implement the 333/266/200MHz Front Side Bus, the AGP 8X/4X
interface, the LPC Super I/O, the DDR *400/333 MHz SDRAM, the 2-
channel AC’97 Audio interface, the USB 2.0 interface and ATA 133/100/
66 data transfer rate. This chapter is to introduce to users every ad-
vanced function of this high performance integration.
** If any difference is found between this manual and the Main-
board you are using, please look up the ERRATA/UPDATE Slip

Chapter 2 Hardware Setup
1. We recommend to install your CPU before any other components.
For detailed installation instructions of processor, you can also refer
to the pamphlet enclosed in your CPU package.
2. Installing a cooling fan with a good heatsink is a must for proper heat
dissipation for your CPU. Get ready an appropriate fan with heatsink
for proper installation. Improper fan and installation will damage your
CPU.
3. In case CPU Vcore, CPU clock or Frequency Ratio is adjustable on
board, please follow the instructions described in the User Manual
for proper setup. Incorrect setting will cause damage to your CPU.

2-1.2 CPU Installation with Socket 462
This mainboard is built with CPU Socket 462 supporting the AMD CPUs
Athlon, Athlon XP and Duron:
• Follow the steps described in this section to install CPU into the on-
board Socket 462.
• After installation of CPU, you must also install a proper cooling fan
on top of the CPU and connect the Fan cable to the CPU fan
connector.
1. First pull sideways the lever of
Socket 462, and then turn it up
900so as to raise the upper layer
of the socket from the lower
platform.
3. Make sure that all CPU pins have
completely entered the socket
and then lower down the lever
to lock up CPU to socket.
2. Configure Pin 1 of CPU to Pin 1
of the Socket, just as the way
shown in the diagram on the
right. Adjust the position of CPU
until you can feel all CPU pins
get into the pin holes of the
socket.

2-2 Memory Installation
How to tackle the memory Modules:
• Make sure to unplug your power supply before adding or removing
memory module. Failure to do so may cause severe damage to both
your mainboard and the memory module.
• Pay attention to the orientation of the DIMM slots. Forcing a DIMM
into a slot improperly will damage the memory module and slot itself.
• Make sure you have the right type of memory module for your
mainboard.
184-Pin DIMM Notch Key Definitions
DRAM Key Position Voltage Key Position
Module Latch
• This series supports up to 2GB unbuffered *DDR 400/333/266 SDRAM,
with 2 DDR DIMM slots on board. Do not insert other type of mod-
ules into these slots. Memory support is upgradable to DDR 400 with-
out guarantee of success in BIOS Setup.
* DDR 400 Module is supported on condition that the module has
passed Soltek DDR 400 Memory Module Validation Test. Soltek
Computer Inc. typically runs a DDR 400 Memory Module Validation
Program for Chipset VIA KT400/P4X400A. Detailed information is
available in Soltek Web Site: www.soltek.com.tw
• DDR DIMM slot has 184-pins and one notch. Insert a DDR SDRAM
vertically into the 184-pin slot with the notch-to-rib matching.

The AGP slot on board supports 1.5V AGP 8X/4X card only. A Rib is
specifically added to the 8X/4X slot so as to match the AGP 8X/4X card.
To insert a 3.3V AGP 2X card into the AGP 4X slot will damage the
system chip and burn the 1.5V circuitry.
An AGP 8X card will support a data transfer rate up to 2GB/sec., while
an AGP 4X card will provide 1GB/sec transfer rate.
