I'm assuming you're running Windows 7 32bit?
32bit OS's only recognise a maximum of 3GB of RAM. So no matter how much extra you put in, it will only ever register as 3GB (sometimes just over like 3.25GB etc).

I'm not sure why it would register just under 3GB - I've never seen that before..

You need to use 64 bit Windows to use more than 4Gb.

You can check under Control Panel>System.
