Hi, I have a question about this, I've searched the web and found 32bit machines will not display the 4GB RAM installed, I also read a machine that runs 64bit OS will show the actual amount of RAM installed, so my question is does the machine with the 32bit OS not really use the full 4GB ? 2559MB is all it is showing, what's that unused GB doing, is it just dead laying there or ...?
Last question, I am going to go w Vista 64bit OS on one of my Dell PC, what hardware do I need to change, I read where optical drives would be one thing, is there anything other hardware items I need to change ?
Try reading this link to explain 32bit OS -vs- 64bit and 4GB of RAM. FYI.. Vista 32bit with SP1 shows 4GB of RAM. It just doesn't address the entire 4GB.
As far as hardware replacement, I guess it depends what you have where the manufacturer does not provide a 64bit driver. I have an XPS 410 and my optical drive works fine in Vista HP 64bit. My printer and video card manufacturer have a 64bit driver that I downloaded. Most of my applications run as 32bit.

Thank you Keith for your terrific and patient answer. The link to the document you provided was exactly what I was looking for.
Unfortunately, I found some other answers from other users in other threads that were very unkind and condescending.
