I own an Alienware Area-51 7500 with XP x32, and an SLI enabled motherboard. I am recently experimenting with having 4 gigs of ram (4x1).
Now, System info shows 2.5 gigs of ram, Task Manager shows 2.62, and Cpuz shows all 4096 megabytes. I know that XP itself (x32) cannot work with more than 3.5 gigs (right?), but then what about my other 1 gig or ram?
When it says that it has only 2.5, does it at the least still use all 4 of my gigs of ram?
I also heard something like SLI boards only being able to go up to 2.5 gigs, but than why is the board able to have 16 gigs of ram??

2.5 gB is low - are you sure that you're using the /pae switch in your boot menu? Check boot.ini (a hidden file in the root directory (C:\)) to see.

Check your Event Viewer to see if there's any errors related to the memory (Start...Run...type in "eventvwr.msc" (without the quotes) and press Enter).

Download this free memory tester and put it on a bootable CD (there's instructions on the website) and boot from the CD to test your memory. Let the test run for a minimum of 3 passes (but overnight is better). If you start getting errors you can stop the test and start trying to figure out what the cause is.

I am not using the /pae switch, or this /3gb switch I have been seeing on Google.
I actually feel afraid of messing around with my boot.ini file...Don't want to piss off the computer, if that might be the case.
The only error Event Viewer shows is Access Failure to my Raid drive, and this error does also pop up accasionally on the bottom right side of the screen...again, I do not know what it means, or what it implies. If you have any ideas about that as well, please let me know.
I haven't done Memtest yet, but I do not believe that the ram are faulty. The computer came with 2x1 and 2/.5 rams, and it still said 2.5 gigs, and I changed the 2x.5 to 2x1 and it still says 2.5 gigs.
I would also like to know whether I am trying to do all this just to 'see' 4 gigs or whatnot on my system information, or does it actually affect the perfomance?

Without testing the RAM you won't know if it's good or bad. Without knowing that, the rest of the troubleshooting (IMO) is futile.

As for what it's doing vs what it's showing, the only thing to do would be to benchmark the system with the original 2.5 gB RAM setup and then do it again with the 4 gB of RAM. But, once again, if you don't know if the RAM is good then you can't make a valid comparison. The difference between 2.5 and 4 gB of RAM isn't very noticeable until you really start stressing the RAM (which most applications just don't do).
