MB970 User’s Manual 7
Installing the CPU
The MB970 board supports an LGA1155 Socket (shown below) for
Intel Sandy Bridge processors.
To install the CPU, unlock first the socket by pressing the lever
sideways, then lift itup 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.

Installing the Memory
The MB970 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.
