7.4 GB of memory is quite much. The system is probably allocating memory for buffers, and not all that memory is actually used.

You can inspect memory usage by running top and then pressing M (to sort processes for memory usage).

Htop is more fitted for this as top wont show the disk caching in the list but will show you that it is used in the top summary. – spydon Nov 06 '13 at 09:12

It most likely not using all that ram, this is a very common misconception when using linux. Linux is using memory that isn't being used for disk caching, if you start something that needs ram linux will stop to use it.

Also, this question is more fitted for SU or askubuntu than stackoverflow.
