1.5.3 Installing a DDR3 DIMM
Make sure to unplug the power supply before adding or removing
DIMMs or other system components. Failure to do so may cause
severe damage to both the motherboard and the components.
1. Locate the DIMM socket on the board.
2. Hold two edges of the DIMM module carefully, and keep away of touching its
connectors.
3. Align the notch key on the module with the rib on the slot.
4. Firmly press the modules into the socket automatically snaps into the mounting notch.
Do not force the DIMM module in with extra force as the DIMM module only fit in one
direction.
 A DDR3 DIMM is keyed with a notch so that it fits in only one
direction. DO NOT force a DIMM into a socket to avoid damaging
the DIMM.
 The DDR3 DIMM sockets do not support DDR DIMMs. DO NOT
install DDR DIMMs to the DDR3 DIMM socket.
