INTRODUCTION

MB740 User’s Manual 1

Introduction

Product Description

The MB740 Mini ITX board incorporates a Socket A processor socket that

supports AMD Geode NX series processors that support processor speed up to

1.4GHz. With the SIS 741CX chipset, it delivers maximum performance for

demanding thin client or embedded applications that require silent system

operation. With a higher processor speed and active cooling, it is best suited for

demanding applications such as graphics and point of sales systems. The board

comes with integrated chipset VGA and Ethernet controllers. Optionally

provided is a Realtek Gigabit Ethernet and daughter cards for CRT2/TMDS or

LVDS/TV out interface.

INSTALLATIONS

Installing the CPU

The MB740 board supports a Socket A processor socket for AMD NX

Series processors.

The Socket A processor socket comes with a lever to secure the

processor. Raise this lever to about a 90°angle to allow the insertion of

the processor. Place the processor into the socket by making sure the

notch on the corner of the CPU corresponds with the notch on the inside

of the socket. Once the processor has slide into the socket, return the

lever to the lock position. Refer to the figures below.

After you have installed the processor into the socket, check if the

jumpers for the CPU type and speed are correct.

NOTE: Ensure that the CPU heat sink and the CPU top surface are in

total contact to avoid CPU overheating problem that would

cause your system to hang or be unstable.
