Installing a DIMM

Unplug the power supply before adding or removing DIMMs or other system components. 

Failure to do so can cause severe damage to both the motherboard and the components.

1. 

Press the retaining clips outward to 

unlock a DDR2 DIMM socket.

2. 

Align a DIMM on the socket such that 

the notch on the DIMM matches the 

break on the socket.

A DDR2 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.

3. 

Firmly insert the DIMM into the socket 

until the retaining clips snap back in place 

and the DIMM is properly seated.

extra force.
