INTRODUCTION
The MS-6340 Micro-ATXVA mainboard is a high-performance
computer mainboard based on VIA®KT133 chipset. The MS-6340 is
designed for the AMD®Socket processor for inexpensive business/
personal desktop markets.
The KT133 chipset consists of the VT8363 system controller (552
pin BGA) and the VT82C686A PCI to ISA bridge (352 pin BGA). The system
controller provides superior performance between the CPU, DRAM, AGP
bus, and PCI bus with pipelined burst, and concurrent operation.
The VT82C686A 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 VT82C686A chipset also improves the IDE transfer rate by
supporting Ultra DMA-33/66 IDE that transfers data at the rate 33/66MB sec.
This mainboard which supports KT133 chipset coupled with
VT8363and VT82C686A is ideal for high performance, high quality, high
energy efficient and high integration desktop AGP/PCI/ISA computer
systems.

HARDWARE INSTALLATION
2.1 Central Processing Unit: CPU
The mainboard operates with AMD®DuronTM/Athlon processor. The
mainboard uses a CPU socket called Socket 462 for easy CPU installation.
The CPU should always have a Heat Sink and a cooling fan attached to
prevent overheating.
3. Press the lever down to
complete the installation.
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.

from the socket. Then, raise
the lever up to a 90-degree
angle.

The mainboard CPU Bus Frequency can be set through BIOS setup.
If CPUClock = 100MHz
Core/Bus ratio = 7
then CPU core speed = Host Clock xCore/Bus ratio
= 700MHz

2.1-3 Fan Power Connectors: C_FAN1/S_FAN1
These connectors support system cooling fan with + 12V. It supports three
pin head connector. When connecting the wire to the connector, always
take note that the red wire is the positive and should be connected to the
+12V, the black wire is Ground and should be connected to GND. If your
mainboard has System Hardware Monitor chipset on-board, you must use a
specially designed fan with speed sensor to take advantage of this function.
For fans with fan speed sensor, every rotation of the fan will send out 2
pulses. System Hardware Monitor will count and report the fan rotation
speed.
Note: Always consult vendor for proper CPU cooling fan.
