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.
