and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to
cause harmful interference, in which case the user will be required to correct
the interference at his own expense.
Notice 1
The changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
Notice 2
Shielded interface cables and A.C. power cord, if any, must be used in order to
comply with the emission limits.

Chapter 1. Introduction
The K7T266 Pro2 (MS-6380 v2.X) series ATX mainboards are high-
performance computer mainboards based on VIA® Apollo KT266A
(VT8366A & VT8233) chipset and designed for the AMD® Athlon™,
Athlon XP or Duron™ (PGA) processor for inexpensive business/personal
desktop markets.
Four models are available for K7T266 Pro2 series motherboards.
They are K7T266 Pro2, K7T266 Pro2-R, K7T266 Pro2-U and K7T266
Pro2-RU. K7T266 Pro2 is the standard version. In addition to standard
features, K7T266 Pro2-R adds support for IDE RAID function, while K7T266
Pro2-U does not support IDE RAID function, but comes with support for the
newest high-bandwidth USB 2.0 technology. The model, K7T266 Pro2-RU,
not only supports USB 2.0 function but also integrates IDE RAID technology on the board.
These models provide rich flexibility in meeting consumers’ diverse
needs for VIA® Apollo KT266A-based motherboards.

utility is just like your PC doctor that can detect the following PC hardware
status during real time operation:
* monitor CPU & system temperatures
* monitor fan speed(s)
* monitor system voltage
* monitor chassis intrusion
If one of the items listed above is abnormal, the program main screen will be
immediately shown on the screen, with the abnormal item highlighted in red.
This screen will continue to be shown,until user disables the warning.

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.
The D-Bracket™, which integrates four Diagnostic LEDs, is optional.
The definitions of the D-Bracket™ LED signals are the same as D-LED™.

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.

1. Pull the lever sideways away
from the socket. Then, raise
the lever up to a 90-degree
angle.
3. Hold the CPU firmly, and
then press the lever down to
complete the installation.

CPU Installation Procedures
2. Look for the cut edge. The
cut edge should point
towards the lever pivot. The
CPU will only fit in the
correct orientation.
The mainboard supports AMD® AthlonTM, Athlon XP and Duron
TM
processors. It 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.

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
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 visit AMD’s web site for more information on proper cooling: http://
www.amd.com/products/cpg/athlon/pdf/cooling_guide.pdf
WARNING! Thermal Issue for CPU

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 3-27.
The default hardware configuration for CPU Clock Frequency is set at
100MHz. Therefore, to use a 133MHz CPU and have it run at 133MHz, you
need to adjust the CPU clock up to 133MHz by changing the CPU clock in the
BIOS Setup utility.
Replacing CPU
While replacing the CPU, always turn off the ATX
power supply or unplug the power cable of the ATX
power supply from grounded outlet first to ensure the
safety of CPU.
Overclocking
This motherboard is designed to support overclocking.
However, please make sure your components are able
to tolerate such abnormal setting, while doing
overclocking. Any attempt to operate beyond product specifications is not recommended. We do not
guarantee the damages or risks caused by inadequate
operation or beyond product specifications.
WARNING!

The mainboard provides 3 sockets for 184-pin unbuffered DDR DIMM

Introduction to DDR SDRAM
You can install PC1600/PC2100 DDR SDRAM modules on the DDR
DIMM slots (DDR 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).
T wo 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.

1. The DDR DIMM has only one notch on the center of module. The
module will only fit in the right orientation.
2. Insert the DIMM memory module vertically into the DIMM slot.
Then push it in.
3. The plastic clip at each side of the DIMM slot will automatically
close.
Volt
DIMM Modules Combination
At least one DIMM module should be installed on the motherboard.
Memory modules can be installed on the slots in any order. The single-/
double-sided memory modules that each DIMM slot supports are listed as
below:
DDR 1 DDR 2 DDR 3
S/D S/D S/D
S (Single Side): 64MB ~ 512MB
D (Double Side): 128MB ~ 1GB

Power Supply
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 plug 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.
ATX
Power Connector
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.
