Introduction
The K7T266 Pro (MS-6380) ATX mainboard is a high-performance
computer mainboard based on VIA® Apollo KT266 chipset and designed for
the AMD® Athlon or Duron (PGA) processor for inexpensive business/
personal desktop markets.
The Apollo KT266 chipset consists of the VT8366 Super Northbridge
and the VT8233 Southbridge. VT8366 provides a PC1600/2100 DDR (Double
Data Rate) solution with support for 200/266MHz Front Side Bus. By using
PC2100 DDR technology, the VT8366 enables 2.1GB/second peak bandwidth
between system memory and Northbridge. The chipset doubles the communication bandwidth between the North and South Bridge to 266MB/sec
through a high-speed V-Link bus. With AGP 4X interface, VT8366 boosts
system performance for 3D graphics and video program.
The VT8233 Southbridge integrates many peripheral controllers
including dual channel UltraDMA-33/66/100 master mode EIDE controller,
AC-link interface, LPC interface, USB controller etc. The VT8233 is compatible with PCI-2.2 specification and supports advanced power management.
The Apollo KT266 chipset provides the optimized performance for
the PC systems based on the latest AMD® processors.

The D-LED uses graphic signal display to help
users understand their system. Four LEDs embedded in
the mainboard provide up to 16 combinations of signals to
debug the system. The 4 LEDs can debug all problems that
fail the system, such as VGA, RAM or other failures. This
special feature is very useful for the overclocking users.
These users can use the feature to detect if there are any
problems or failures.

Hardware Setup
This chapter provides you with the information about hardware setup
procedures. While doing the installation, be careful in holding the components and follow the installation procedures. For some components, if you
install in the wrong orientation, the components will not work properly.
Use a grounded wrist strap before handling computer components.
Static electricity may damage the components.

Central Processing Unit: CPU
The mainboard supports AMD® AthlonTM and DuronTM processor.
The mainboard uses a CPU socket called Socket A for easy CPU installation.
Make sure the CPU has a Heat Sink and a cooling fan attached on the top to
prevent overheating. If you do not find the Heat Sink and cooling fan,
contact your dealer to purchase and install them before turning on the
computer.
CPU Installation Procedures
1. Pull the lever sideways away
from the socket. Then, raise
the lever up to a 90-degree
angle.
2. Look for the cut edge. The
cut edge should point
towards the lever pivot. The
CPU will only fit in the
correct orientation.
3. Hold the CPU firmly, and
then press the lever down to
complete the installation.

Thermal Issue for CPU
!
WARNING!
thermal environment is key to reliable operation. As such, the processor must
be maintained in the specified thermal requirements. AMD recommends the
use of high performance thermal interface material.
AMD Athlon/Duron processor with a speed of 600MHz and above requires LARGER heatsink and fan. You also need to add thermal grease between the CPU and heatsink to improve heat dissipation. Then, make sure that
the CPU and heatsink are securely fastened and in good contact with each
other. These are needed to prevent damaging the processor and ensuring
reliable operation.
You can check AMDs web site for more information on proper cooling: http:/
/www.amd.com/products/cpg/athlon/pdf/cooling_guide.pdf
As processor technology pushes to faster speeds and higher
performance, thermal management becomes increasingly crucial when building computer systems. Maintaining the proper

Chapter 2
CPU Core Speed Derivation Procedure
If CPU Clock = 100MHz
Core/Bus ratio = 7
then CPU core speed = Host Clock x Core/Bus ratio
= 100MHz x 7
= 700MHz
CPU Clock Frequency Selection through BIOS
To set the clock frequency of the CPU installed on the motherboard,
refer to Hardware Monitor Setup of BIOS on page 3-26.
The default hardware configuration for CPU Clock Frequency is 100MHz.
Therefore, to use a 133MHz CPU, you need to adjust the CPU clock up to
133MHz by changing the CPU clock in the BIOS Setup utility.
While replacing the CPU, always turn off the ATX
!
WARNING!
power supply or unplug the power cable of the ATX
power supply from grounded outlet first to ensure the
safety of CPU.

Hardware Setup
Memory
The mainboard provides 3 sockets for 184-pin, 2.5V DDR DIMM with 6
memory banks. To operate properly, at least one DIMM module must be
installed.
DDR DIMM Slots
(DDR 1~3)
You can install PC1600/PC2100 DDR SDRAM modules on the DDR
DIMM slots (DIMM 1~3).
DDR (Double Data Rate) SDRAM is similar to conventional SDRAM,
but doubles the rate by transfering data twice per cycle. It transfers 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).
Two types of DDR are available at the time of writing: PC1600 & PC2100.
PC1600 DDR SDRAM running at 100MHz will produce about 1.6GB/s memory
bandwidth. 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.

Chapter 2
DDR Module Installation
You can install either single sided or double sided 184-pin DDR DIMM
modules into DDR DIMM slots to meet your needs. Different from the SDR
DIMM, the DDR DIMM has only one notch on the center of module. The
number of pins on either side of the breaks are different. The module will only
fit in the right orientation.
Single Sided DIMM
Double Sided DIMM
1. Insert the DIMM module vertically into the DDR DIMM slot. Make sure the
notch is on the right orientation.
2. The plastic clips at sides of the DIMM slot will automatically close.

Power Supply
The mainboard supports ATX power supply for the power system.
Before inserting the power supply connector, always make sure that all components are installed properly to ensure that no damage will be caused.
ATX 20-Pin Power Supply
This connector allows you to connect to an ATX power supply. To
connect to the ATX power supply, make sure the plugs of the power supply is
inserted in the proper orientation and the pins are aligned. Then push down
the power supply firmly into the connector.
