I would expect that if you used 32 bit your ram would be significantly less as i suspect your system is using at least 512MB for graphics + whatever else it needs to run, as long as it reports in system properties that you have 4GB then thats what is available for you to use, your system will use as much memory as it needs.
Task manager will show what you are using at that time for whatever purpose is required, be it 1gig or 1MB.
Your pc could be doing 3 tasks and use 2gig or doing 1 task and use 2gig it uses what it thinks it need to run efficiently.
hope that helps
