MSI MS-6380 User manual

Introduction
1-1
The K7T266 Pro (MS-6380) ATX mainboard is a high-performan e
omputer mainboard based on VIA® Apollo KT266 hipset and designed for
the AMD® Athlon or Duron (PGA) pro essor for inexpensive business/
personal desktop markets.
The Apollo KT266 hipset onsists 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 te hnology, the VT8366 enables 2.1GB/se ond peak bandwidth
between system memory and Northbridge. The hipset doubles the ommu-
ni ation bandwidth between the North and South Bridge to 266MB/se
through a high-speed V-Link bus. With AGP 4X interfa e, VT8366 boosts
system performan e for 3D graphi s and video program.
The VT8233 Southbridge integrates many peripheral ontrollers
in luding dual hannel UltraDMA-33/66/100 master mode EIDE ontroller,
AC-link interfa e, LPC interfa e, USB ontroller et . The VT8233 is ompat-
ible with PCI-2.2 spe ifi ation and supports advan ed power management.
The Apollo KT266 hipset provides the optimized performan e for
the PC systems based on the latest AMD® pro essors.

Hardware Setup
This chapter provides you with the information about hardware setup
procedures. While doing the installation, be careful in holding the compo-
nents 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 PU firmly, and
then press the lever down to
complete the installation.

2. Look for the cut edge. The
cut edge should point
towards the lever pivot. The
PU will only fit in the
correct orientation.
The mainboard supports AMD® AthlonTM and DuronTM processor.
The mainboard uses a PU socket called Socket A for easy PU 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.

Thermal Issue for CPU
As processor technology pushes to faster speeds and higher
performance, thermal management becomes increasingly cru-
cial 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 600MH and above re-
quires LARGER heatsink and fan. You also need to add thermal grease be-
tween the PU and heatsink to improve heat dissipation. Then, make sure that
the PU 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 AMDs web site for more information on proper cooling: http:/
/www.amd.com/products/cpg/athlon/pdf/cooling_guide.pdf

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

Hardware Setup

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.
Memory
DDR DIMM Slots
(DDR 1~3)
You can install P 1600/P 2100 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. onventional 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: P 1600 & P 2100.
P 1600 DDR SDRAM running at 100MHz will produce about 1.6GB/s memory
bandwidth. P 2100 running at 133MHz will produce 2.1GB/s memory
bandwidth. High memory bandwidth makes DDR an ideal solution for high
performance P , workstations and servers.

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.
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.

TX 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.

The mainboard supports ATX power supply for the power system.
Before inserting the power supply connector, always make sure that all compo-
