To install a memory module:
1. Perform steps 1 and 2 of the previous section.
2. Locate an empty DIMM slot on the system board.
3.
If necessary, open the holding clips of the selected DIMM slot.
4. Remove the memory module from its protective packaging, handling it by the edges.
5. Use both hands to hold the module by the edges, and then insert it perpendicularly into the slot
until it locks into place.
The DIMM slots are structured to ensure proper installation. If you insert a memory module but it
does not fit easily into the slot, you may have inserted it incorrectly. Reverse the orientation of the
module and insert it again.
