KM400T-8X Series
Chapter 1. Getting Started
Introduction
Congratulations on choosing the KM400T-8X Series mainboard! The KM400T-8X series includes
the KM400T-8X PRO and KM400T-8X. These are based on VT8377 and VT8235 chipsets. It also
supports AMD®Athlon XPTM/ AthlonTM/ DuronTM/ BartonTM Processors with a FSB (Front Side Bus)
frequency of 200/ 266/ 333 MHz.
The KM400T-8X Series provide 2 sockets using 184 pin DDR SDRAM with a total capacity of up to
2GB. You can install DDR333/ 266/ 200 (PC2700/ 2100/ 1600) SDRAM. This mainboard is capable
of DDR400 without overclocking, simply by using DDR400 SDRAM and making the appropriate
adjustments to the BIOS configuration. (For more details please refer the Frequency / Voltage
Control section.)
The KM400T-8X Series provide one AGP Slot for 2X/ 4X/ 8X (1.5V only) AGP cards.
The KM400T-8X Series include built in IDE facilities that support Ultra DMA 33/66/100/133. The
KM400T-8X Series also comes with an Audio Codec (VIA VT1616) which supports high quality 6
channel audio (Super 5.1 Channel Audio Effect).
The KM400T-8X Series also include CPU Over Temperature Protection (OTP). When CPU
temperature rises above normal values, the system will automatically shut down to protect your
system from overheating. But the OTP is only functional when using an Athlon XPTM CPU.
The KM400T-8X Series also comes with six USB 2.0 ports.
The KM400T-8X PRO also comes with a LAN Chip (VIA VT6103) which supports a back panel
LAN port.

detect when the system is unable to handle over-clocking configurations during POST
stage. Once detected the system will reset the configurations and reboot the system after
five seconds. On most systems you would need to remove the cover of your system and
re-jumper the clear CMOS switches on the mainboard when your system encounters
over-clocking problems. With the “Watch Dog Timer”, overclocking settings will be
automatically cleared and reset.

Hardware Installation
This section will assist you in quickly installing your system hardware. Wear a wrist ground strap
before handling components. Electrostatic discharge may damage your system components.
CPU Processor Installation
This mainboard supports AMD®Athlon XPTM/ AthlonTM/ DuronTM/ BartonTM processors using a
Socket A (Socket 462 Pin package). Before building your system, we suggest you visit the AMD
website and review the processor installation procedures. http://www.amd.com
CPU Socket A Configuration Steps:
1. Locate the CPU socket on your mainboard and nudge the lever away from the socket. Then lift
the lever to a 90-degree angle.
2. On the socket, locate the corner that has the pin-1 receptor. This corner will be near to the end
of the lever. Match the corner on the CPU with the pin-1 receptor on the socket and lower the
CPU onto the socket. The bottom of the CPU should be flush with the face of the socket.
Pin-1
Receptor
Corner
3. Lower the lever until it snaps back into position. This will lock down the CPU.
4. Smear thermal grease on top of the CPU. Lower the CPU fan onto the CPU and use the clasps
on the fan to attach it to the socket. Finally, extend the power cable from the fan and insert it
onto the CPUFAN adapter.

FAN
Headers
Three power headers are available for cooling fans, which play an important role in maintaining the
ambient temperature in your system.
Attention
Overheating may damage the CPU and other sensitive components.
Please check the installation completely before starting the system.
Make sure the heatsink and the CPU fan are properly installed.
Attention
This system has a BIOS configuration feature that issues a warning
(during POST) when the CPU fan is not plugged in or is not
functioning. In order to make use of this feature. You must make sure
that the CPU power cable is attached specifically to the “CPUFAN”
header. The BIOS configuration option is described in the “Hardware
Monitor” section of the BIOS Setup Utility Chapter.

Memory Installation
The KM400T-8X Series contain 2 sockets, which use 184- pin DDR SDRAM with a total memory
capacity of up to 2 GB. You can install unbuffered/ registered non-ECC DDR333/ 266/ 200
e corresponding pattern in the
DIMM slot. This ensures that the module is inserted properly.

(PC2700/ 2100/ 1600) SDRAM.
RAM Module Installation:
1. Pull the white plastic tabs on each side of the slot away from the slot.
Match the notch on the button of the RAM module with th2.
Lower the RAM module into the DIMM Slot and press firmly using both thumbs until the
module snaps into place.
4. Repeat steps 1, 2 and 3 for the remaining RAM modules.
