memory

As a last resort to my question, I am yet to try the mem parameter of kernel to force it to use the specified amount of RAM. Short Summary - I can only see 3.2GB RAM on a 64bit OS and am not sure ifs a hardware limitation, so wants to try as I found a post on Ubuntuforums.

My question is if its ok to play with my resident Ubuntu install or should I be using a live bootable usb? What values do I try (I have 6GB with only 3.2GB being usable) and how to keep it safe? I don't want to burn any of my hardware component at this point of time or make the system unbootable.

Running Ubuntu 11.10 with kernel 3.0.0-13-generic
