Insert the DIMM memory module vertically into the DIMM slot. Then push it in until the golden finger on the memory module is deeply inserted in the socket. 3. The plastic clip at each side of the DIMM slot will automatically close. Volt Notch Important You can barely see the golden finger if the module is properly inserted in the socket. 2-8
