Introduction
The MS-6341 ATX mainboard is a high-performance computer
mainboard based on AMD®761 chipset and VT82C686B. The MS-6341 is
designed for the AMD®Duron & Thunderbird processor for inexpensive
business/personal desktop markets.
The AMD-761 system controller features the AMD Duron system
bus, system memory controller, accelerated graphics port (AGP) controller,
and peripheral component interconnect (PCI) bus controller. The AMD-761
system controller is also designed to support 266-MHz DDR SDRAM
DIMMs.
The VT82C686B integrates all system control functions such as ACPI
(Advances Configuration and Power Interface). The ACPI provides more
Energy Saving Features for the OSPM (OS Direct Power Management)
function. The VT82C686B chipset also improves the IDE transfer rate by
supporting Ultra DMA-33/66/100 IDE that transfers data at the rate 33/66/
100MB/sec.

PCAlertTM III
The PC AlertTM III is a utility you can find in the CD-ROM. The utility
is just like your PC doctor that can detect the following PC hardware status
during real time operation:
* monitor CPU & system temperature
* monitor fan speed
* monitor system voltage
* monitor chassis intrusion
If one of the items above is abnormal, the program main screen will be imme-
diately shown on the screen, with the abnormal item highlighted in red. This
will continue to be shown,until user disables warning.

The D-LEDTM uses graphic signal display to
help you understand your system. There are 4 LEDs
embedded in the mainboard which provides up to
16 combination of signals to debug 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. The users can use this feature to detect if there are any
problems or failures while doing the overclocking.

Hardware Setup
This chapter provide you with the information about hardware setup
procedures. While doing the installation, be carefu in l holding the compo-
nents and follow the installtion procedures. For some components, if you
install in the wrong orientation, the components will not work properly.
Besides, use a grounded wrist strap before handling computer
components. Static electricity may damage the components.

Central Processing Unit: CPU
The mainboard supports AMD®DuronTM and AthlonTM processor.
The mainboard uses a CPU socket called Socket A for easy CPU installation.
Make sure the CPU have a Heat Sink and a cooling fan attached to prevent
overheating. If you do not find the Heat Sink and cooling fan, contact your
dealer or purchase 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. Locate Pin 1 in the socket
and look for the white dot or
cut edge in the CPU. Match
Pin 1 with the white dot/cut
edge. Then, insert the CPU.
It should insert easily.
3. Press the lever down to
complete the installation.

CPU Core Speed Derivation Procedure
The mainboard can automatically set the CPU Host Bus Frequency Clock.
If CPUClock = 100MHz
Core/Bus ratio = 7
then CPU core speed = Host Clock x Core/Bus ratio
= 100MHzx7
= 700MHz

CPU FSB Frequency : SW1
TheSW1isusdto settheCPU FSBFrequencyfrom 100MHzto133MHz.
The CPU FSB frequency can also be adjusted in BIOS. Please refer to Chapter
3 for more information.
Overclocking
This motherboard are designed to support overclockingo.
However, please make sure your components are able to
tolerate such abnormal setting, while doing overclocking.
Any attempts to operate beyond product specifications are
not recommended. We do not guarantee the damages or
risks caused by inadequate operation or beyond product
specifications.

Memory Installation
The mainboard provides 4 sockets for 184-pin, 3.3V DDR-DIMM with
8 memory banks. To operate properly, at least one DIMM module must be
installed. The mainboard supports the memory size up to 4GB.

DDR-DIMM2
DDR-DIMM3
DDR-DIMM4
·Note:
The mainboard supports two kinds of DDR-DIMM: Unbuffered, Registered.
Unbuffered can only be inserted into DDR-DIMM1 and DDR-DIMM2 while
Registered can be inserted into DDR-DIMM1 ~ DDR-DIMM4. Please do not
insert the two kinds of DDR-DIMM at the same time.

Module Installation Procedures
You can intall the single sided or double sided DIMM according to
your needs. Different from the SDRAM DIMM, the DDR DIMM has only one
notch on the center of module. The pins on the either side of the breasks are
different. Pay attention to the orientation as shown below. The module will
only fit in the right orientation.
1. Insert the DIMM module vertically into the DIMM slot. Make sure the
notch is on the right orientation.
2. The plastic clip at the side of the DIMM slot will automatically close.
