IMPORTANT INFORMATION
1. When an Intel® Core™i7 processor is installed on
board, please install an external graphics card to
have graphics output, because Intel® Core™I7
processor does not support graphics in the
microprocessor. Also, please note when an Intel®
Core™i7 processor is installed, the memory module
should be installed in DIMM1 socket; otherwise, the
system will not boot.
2. When an external graphics card is installed on the
motherboard, regardless of they type of processor
on board, the onboard VGA and DVI ports/
connectors will not function. Use the graphics output
connector on the graphics card.
3. The onboard PCI-E(x8) slot supports PCI-E(x4)
link only. Please note that a PCI-E(x8) card installed
on the board may or may not function normally.

Introduction
Product Description
The MB950 ATX motherboard offers the latest Socket H (LGA1156)
supporting the Intel® Core™ i7, Core™ i5, Core™ i3 processors or the
Intel® Pentium® processor G6950, all developed on Intel’s newest
microarchitecture, formerly codenamed “Nehalem,” and using Intel’s
32nm and 45nm process technologies.
Designed as an enterprise-performance ATX motherboard, the MB950 is
ideal for the latest generation of POS, kiosk, automation and multimedia
applications such as gaming. Based on the Intel® Q57 chipset, the
MB950 supports the processor-integrated graphics to provide two
display streams in combination of the onboard VGA CRT and DVI-D
video interfaces. Up to 16GB of maximum memory can be configured in
four DDR3 socket at 1066/1333MHz.
In addition to the impressive computing performance, the board is
equipped with high-end connectivity comprised of dual Gigabit LAN
controllers, six SATA-II ports, one IDE, fourteen USB 2.0 ports, four
COM ports and high-definition audio. Should greater performance or
expansion be required, add-on cards can be connected to the onboard
PCI-E(x16), PCI-E(x8) [(x4) Link], PCI-E(x1), four PCI, and ISA slot.

Installing the CPU
The MB950 board supports an LGA1156 Socket (shown below) for Intel
Clarkdale processors.
.
To installthe CPU, unlock first the socket bypressing the lever sideways,
then lift it up to a 90-degree. Then, position the CPU above the socket
such that the CPU corner aligns with the gold triangle matching the
socket corner with a small triangle. Carefully insert the CPU into the
socket and push down the lever to secure the CPU. Then, install the heat
sink and fan.
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.

MB950 User’s Manual 7
Installing the Memory
The MB950 board supports four DDR3 memory socket for a maximum
total memory of 16GB in DDR3 DIMM 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.
