Introduction
Product Description
The MI945X 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® GMA X3500) 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 dual channel DDR3 800/1066MHz
two SODIMM sockets on board, the board supports up to 4GB of 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 GMA X3500
graphics architecture also takes advantage of the high-performance Intel
processor. Intel GMA X3500 graphics supports Dual Independent Display
technology.
The main features of the board are:
Supports Intel® Mobile Core 2 Duo/Core 2 Quad Processor (Penryn)
Supports up to 2.93GHz, 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-E (x16) slots

Installations
This section provides information on how to use the jumpers and
connectors on the MI945X in order to set up a workable system. The
topics covered are:
Installing the CPU ................................................................................. 8
Installing the Memory ........................................................................... 9

Connectors on MI945X....................................................................... 14

INSTALLATIONS
Installing the CPU
The MI945X board supports a Socket M socket for Intel® CoreTM 2
Duo, Intel® Celeron 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.
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.

INSTALLATIONS
Installing the Memory
The MI945X board supports two DDR3 memory socket for a maximum
total memory of 4GB in DDR3 memory type.
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.
