Important
 A DDR3 SO-DIMM is keyed with a notch so that it fits in only one
direction. DO NOT force a SO-DIMM into a socket to avoid damaging
the SO-DIMM.
 The DDR3 SO-DIMM sockets do not support DDR2 SO-DIMMs. DO
NOT install DDR2 SO-DIMM to the DDR3 SO-DIMM socket.
Caution
Make sure to unplug the power supply before adding or removing
SO-DIMMs or other system components. Failure to do so may cause
severe damage to both the motherboard and the components.
