THE 2807950 MINI ITX MOTHERBOARD
2807950 User's Manual

Introduction
Product Description
The 2807950 Mini ITX board incorporates the Mobile Intel® GM965 Express
Chipset for Embedded Computing, consisting of the Intel® GM965 Graphic
Memory Controller Hub (GMCH) and Intel® I/O Controller Hub (ICH8-M), an
optimized integrated graphics solution with a 533MHz 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 X3100 (Intel® GMA X3100) architecture, operates at core speeds of
up to 400 MHz. It features a low-power design, is validated with the Intel® Core
2 Duo and Intel® Celeron processors on 65nm process. With dual channel
DDR2 667MHz two DIMM socket 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 GMA X3100
graphics architecture also takes advantage of the high-performance Intel
processor. Intel GMA X3100 graphics supports Dual Independent Display
technology.
The main features of the board are:
Supports Intel® CoreTM 2 Duo (Merom 800MHz), Intel® Celeron
Supports up to 2.4GHz, 533MHz/800MHz FSB
Two DDR2 SDRAM DIMM, Max. 4GB memory
Onboard 10/100 BaseT and Marvell PCI-Express Gigabit LAN
Intel® GM965 Express VGA for CRT / LVDS
2x SATA, 6x USB 2.0, 2x COM, Watchdog timer, 1394
1x MiniPCI, 1x PCI, 1xPCI-E(x1) slots, optional DVI
Optional daughter cards:
3901080: Chrontel 7308, supports 24 bit single or dual LVDS channel
3901220: Chrontel 7021, supports CRT
3901100: Chrontel 7307C, single DVI (connector on cable)

Installing the CPU
The 2807950 board supports a Socket 478MN (MEROM) processor
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.
