2.7.4 Installing a 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.

Reinstall the CPU fan and heatsink assembly before installing the DIMM(s) to avoid damaging the retaining clips of the DIMM sockets. Refer to the previous section for details on how to reinstall the CPU fan and heatsink assembly.

To install a DIMM:

1.Locate the DIMM sockets in the motherboard.

2.Unlock a DIMM socket by pressing the retaining clips outward.

3.Align a DIMM on the socket such that the notch on the DIMM matches the break on the socket.

4.Firmly insert the DIMM into the socket until the retaining clips snap back in place and the DIMM is properly seated.
