I believe you are right. I was trying to write an explanation and got myself all confused, so gave up. So, thank you, yeah, I was lead to believe that PAE would address that.

So it should be good. Regardless, if this was not a 64-bit cpu wouldn't pae address that? Or does that require 64-bit instructions also? I thought pae was specifically for that type of scenario?

It has 4 slots which are currently occupied by 1 GB DIMMS. I searched a bunch of Dell forums and some people were able to get this system to upgrade to 8GB of ram while others could only get the 4GB to work. I don't want to waste any money here, so I'm hoping to find someone who has 2GB PC 4200 DIMMS they are willing to part with?
