I recently installed 2 4GB RAM modules in my laptop in place of the single 4GB module the machine came with. In my system information it say that I have 3 GiB of RAM and 6.7 GiB available to Linux. I'm not sure what this means and why it's so low, especially where the 3GiB come from.
Can anybody enlighten me on this?
