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.
