I've seen that a problem to this is that I am operating on a 32-bit system. I am currently on a 64-bit Operating System and a x64-based processor. My processor is a single operating processor- Intel(R) Pentium(R) CPU G3220T 2.60GHz. I have 6GB of RAM and only 3.17 usable. How do I allow my computer to use all/most of the RAM?
