Hi guys,
like always I try to do my own research and I end up more confused. Here's the story; I got a good deal on these memory sticks to upgrade both my desktops I have at home. In total I got 6 1GB Kingston sticks for $150. My question is about my HP Media Center m1297c Desktop. I looked at the specifications and it says it can handle 4.0 GB (4 X 1 GB) of memory. I installed all for sticks and looked at My System Properties and this is where the questions began.

My System Properties shows only 3 GB of Ram??I started looking for more information and found out that Windows XP can only handle 3.3 GB for a 32 bit system which is apparently what I have (learned something new). I keep looking on the HP site and found out how to verify my memory and confirming the total memory installed with BIOS. The BIOS shows that I have all four Ram's installed. Why is my system properties only showing 3 GB should it not at least show 3.3 GB?? Help! These are my computers specifications:

and these are some HP links where I found some of my computers information:

This is the HP link that really confused me: Upgrading Memory Beyond Three Gigabytes (3GB) in Windows XP

What does this mean?: "Above 3 GB, all memory may not be available due to system resource requirements. The memory above 3 GB is used for PCI I/O and other system resources"???.

In the section on verifying how much memory is used by Windows #3 states: "The memory shown is the memory used by Windows. When 4GB of memory is installed, approximately 3.5 can be used by Windows".

I have 4 GB installed and I don't know why I am only showing 3 GB?? Should I at least be showing 3.3 GB because of the my Windows XP limitations or should I be showing 3.5 because that's what the link on verifying my memory states. I just want to know if I have done something wrong or is the 4th Ram stick at this moment just a space filler?? Any help would be greatly appreciated.
