I think you have been deceived by the original post; by belief is that the OP is reading the "free" column of the free output and not the
"total" column. In this case, his system is seeing all the memory in the box, but it is using it

To the OP:
you have bought a lot of ram, and you are using it (or at least half of it, anyway), why do you have a problem with that? Was there a reason that you wanted to keep it unused?
You should also note and distinguish the difference between 'buffers' and memory used for user processes. Linux is famously 'lazy' about swapping back out memory used for buffers and cache unless the memory is needed. This is the right strategy under many circumstances, but it does cause many people to complain the linux is in some way 'bad' with its memory usage.
If, on the other hand, you believe that certain applications have memory leaks, you need to look at the various applications over time and how it grows (and there can be legitimate reasons for that, too).
