Installing the CPU
The MB980 board supports an LGA1150 Socket (shown below) for Intel
Sandy Bridge 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.
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.
