Installing DDR Modules
1. The DDR DIMM has only one notch on the center of module. The module will only
fit in the right orientation.
2. 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
MSI Reminds You...
You can barely see the golden finger if the module is properly inserted
in the socket.
