slot and supports up to 2GB system memory.
2.3.1 Installing DDRII 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.
3. The plastic clip at each side of the DIMM slot will automatically
close.
Note You can barely see the golden finger if the memory module is
properly inserted in the DIMM slot.
