Let me first say that I am fully aware the maximum amount of RAM a 32-bit OS can read is 4096 MB.
Since I built this computer earlier this year I have been running 2 GB of RAM and haven't had any issues, but I found a nice deal on Black Friday and ended up obtaining another 5 GB. I have 32-bit versions of both XP Pro and Vista Ultimate, so I fully expected I would have to upgrade to 64-bit to utilize all this RAM (if I even have anything that will come near utilizing all of it), but then I saw this in Vista:
So now I am a little confused. As far as I know Vista should not be reporting more than ~3 GB of RAM. XP is only reporting about 3 GB, so I am not really sure what's up. I googled it a bit but wasn't able to find anything, and either way with a 32-bit OS it should be mathematically impossible for it to read all 7 GB of RAM. Does anyone here know something I don't?
