I have a Dell system with 4GB of RAM, but XP pro 32bit which says I have only 3GB of RAM.  I assume going to XP Pro 64 would solve this, but I thought it strange that XP pro 32 maxxed at 3GB ?  SHouldn't it be 2 or 4 or something even ?

My Dell is 64 bit, but was purchased just as XP 64 was an option, but non of our software offered 64 bit versions at that time, so I opted for XP 32.

Thanks
