I currently have 2GB of RAM with this schema:

Slot 0: 1GB (Channel 1)
Slot 1: N/A (Channel 2)
Slot 2: 1GB (Channel 1)
Slot 3: N/A (Channel 2)

May I add a 2GB of RAM in Slot 1 even if it's in Dual-Channel? (2GB is not enough for .NET and Web programmation!)

Yes you can. They must be added in like pairs to take advantage of Dual Channel Mode. dual Channel Mode will provide a performnce improvement.

As RAM is relatively inexpensive, 2X2GB might be a better choice.

Note that 4GB is normally max if using a 32Bit OS.

If you have 2X1GB DIMMs now, adding one 2GB DIMMM will give you 4GB total. That may report as less depending on things like Integrated Video and other factors

You may add a 2GB DIMM for a total of 4GB –  Dave M Apr 10 '12 at 1:24
