INTRODUCTION
Introduction
Product Description
The MI946F Mini ITX board incorporates the Mobile Intel® GM45 Express
Chipset for Embedded Computing, consisting of the Intel® GM45 Graphic
Memory Controller Hub (GMCH) and Intel® I/O Controller Hub (ICH9-M), an
optimized integrated graphics solution with a 1066MHz and 800MHz front-side
bus. Dimensions of the board are 170mm x 170mm.
The integrated powerful 3D graphics engine, based on Intel® Graphics Media
Accelerator X3500 (Intel® GMA4500MHD) architecture, operates at core
speeds of up to 533 MHz. It features a low-power design, is validated with the
Intel® Core 2 Duo processors on 45nm process. With two SoDIMM sockets
supporting dual channel DDR3 1066MHz on board, the board supports up to
4GB of DDR2 system memory.
Intel® Graphics supports a unique intelligent memory management scheme called
Dynamic Video Memory Technology (DVMT). DVMT handles diverse
applications by providing the maximum (384MB) availability of system memory
for general computer usage, while supplying additional graphics memory when a
3D-intensive application requests it. The Intel GMA4500MHD graphics
architecture also takes advantage of the high-performance Intel processor. Intel
GMA4500MHD graphics supports Dual Independent Display technology.
The main features of the board are:
Supports Intel® CoreTM 2 Duo (Penryn 1066MHz)
Supports up to 2.53GHz, 1066MHz/800MHz FSB
Two DDR3 SoDIMM, Max. 4GB memory
Onboard Gigabit PHY and Intel PCI-Express Gigabit LAN
Intel® GM45 Express VGA for CRT / LVDS
4x SATA, 8x USB 2.0, 4x COM, Watchdog timer
1x Mini PCI-E (Mini Card), 1x PCI, 1xPCI-E(x1) slots

INSTALLATIONS
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.
Installing the CPU
The MI946F board supports a Socket 478MN (Merom) processor socket
for Intel CoreTM 2 Duo (Penryn), mobile processors.
The processor socket comes with a screw to secure the processor. As
shown in the left picture below, loosen the screw first before inserting 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, fasten the screw.
Refer to the figures below.

Installing the Memory
The MI946F board supports two DDR3 memory socket for a maximum
total memory of 4GB.
Installing and Removing Memory Modules
To install the DDR3 modules, locate the memory slot on the board and
perform the following steps:
1. Hold the DDR3 module so that the key of the DDR3 module aligned
with that on the memory slot.
2. Gently push the DDR3 module in an upright position until the clips of
the slot close to hold the DDR3 module in place when the DDR3
module touches the bottom of the slot.
3. To remove the DDR3 module, press the clips with both hands.
