What's the difference with single and dual channels?

If I have 2 4GB RAM sticks and placed them in a dual channel setup, does it mean I have 8GBs or what?

Yes, you have 8GB. The amount of RAM you have has nothing to do with the RAM being dual channel. RAM set up in a dual channel configuration has, as the name suggests, two channels through which data is sent. Compared to single channel, dual channel RAM theoretically has double the bandwidth. However, in real world performance, the benefit of running RAM in dual channel mode is only ~5%.

Thank you for the very simple explanation.

Why can't other sources just say the simple thing and stop being so god [bleep] verbose?

Thanks for your help.
