Installing Memory Modules
1. The memory module has only one notch on the center and will only fit in the right
orientation.
2. Insert the memory module vertically into the DIMM slot. Then push it in until the
golden finger on the memory module is deeply inserted in the DIMM slot. The plastic
clip at each side of the DIMM slot will automatically close when the memory module
is properly seated.
3. Manually check if the memory module has been locked in place by the DIMM slot
clips at the sides.
Important
You can barely see the golden finger if the memory module is properly inserted in the
DIMM slot.
