Physical Address Extension (XP)

[jdb691rx]

I just right clicked "my computer" and chose properties.
Just below where it lists the ram ammount, it has the words "Physical Address Extension"
I have never noticed that before, can anyone tell me what it means?

Thanks in advance

Jack
My system is as follows.
AMD 3500 64bit processor, on a ASUS A8V board
Nvidia 5900 graphics card
Creative 5.1 sound card
1 Gig of ram.

Take a look at this. It appears to be a way to allow the use of more than 4 GB of memory on 32-bit processors, but since you have a 64-bit processor, I'm not sure exactly what the point of it is.

Another good read wrt DEP http://www.microsoft.com/technet/pro...1bd1ef227.mspx is a good read.

Many thanks for the quick replies. I have read throught the articles from the links you supplied.
What puzzles me is that I am sure that it was not there last week.
Could Windows update have something to do with it being there now?

Did you recently install Service Pack 2?

I have had Service Pack two installed since it came out.

I have just had a look at my other computer on my home network, which also has an AMD 64 bit processor.
It has exactly the same message.
I used Windows update at the weekend on both of them, and downloaded quite a few things, so perhaps it came with that.
Anyway, as I said, I was just curious about it.
The linked articles were very interesting and informative, and on following links within the articles I now know what "Physical Address Extension" means.

Thank you for the prompt replies.
