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 MB968 board supports an LGA1150 Socket (shown below) for Intel
Clarkdale processors.
To install the CPU, unlock first the socket by pressing 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.

Installing the Memory
The MB968 board supports four DDR3 memory socket for a maximum
total memory of 32GB 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.

J2: System Function Connector
J2 provides connectors for system indicators that provide light indication
of the computer activities and switches to change the computer status. J2
is a 20-pin header that provides interfaces for the following functions
Pin 2, 4, 6, 8: Speaker
This connector provides an interface to a speaker for audio tone
generation. An 8-ohm speaker is recommended.
Pin 1, 3, 5: Power LED
The power LED indicates the status of the main power switch.
Pin 13, 14: ATX Power ON Switch
This 2-pin connector is an “ATX Power Supply On/Off Switch” on
the system that connects to the power switch on the case. When
pressed, the power switch will force the system to power on. When
pressed again, it will force the system to power off.
Pin 17, 18: Reset Switch
The reset switch allows the user to reset the system without turning
the main power switch off and then on again. Orientation is not
required when making a connection to this header.
