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 series 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
900 so 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.

• This series supports up to 3GB unbuffered *DDR 400/333/266 SDRAM,
with 3 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.
• 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.

An indicator LED1 is designed on board. Whenever system is started
or is in STR status (Suspend to RAM), all the DIMM slots on board will
also get powered on with the set voltage, resulting in LED1 lighting up.
This indicator LED1 is to warn users that, whenever DIMM slot is pow-
ered on, no memory module should be removed from or added into it.

2-3 AGP Slot Installation
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.
