These DIMM slots are intended for system memory modules.
Installing Memory Modules
1. Locate the DIMM slots on the mainboard. Flip open the retaining clip at each side
of the DIMM slot.
2. Align the notch on the DIMM with the key on the slot. Insert the DIMM vertically into
the DIMM slot. Then push it in until the golden finger on the DIMM is deeply inserted
in the DIMM slot. The retaining clip at each side of the DIMM slot will automatically
close if the DIMM is properly seated.
3. Manually check if the DIMM has been locked in place by the retaining clips at the
sides.
4. Follow the same procedures to install more DIMMs if necessary.
Important
You can barely see the golden finger if the DIMM is properly inserted in the
DIMM slot.
