4 GB of RAM in XP

Hi

I currently configuration under Windows XP with 4 GB of RAM. I know xp 32 bit handles only 3.2 GB but I wanted to know if the dual channel worked well in games and games used the 4 GB of RAM even though Windows does not recognize.

I have 2 * 2 GB Dual and works very well. In terms of games I doubt that a game is currently need 4 GB of RAM!

This is NOT a problem but windows hardware.
Other applications can use the ram not accessible for the simple reason that the address range of ram "missing" are mapped the IO, the ram graphics etc!

io mapping and graphics RAM is a what.
why when a 2 GB of RAM this mapping is not the RAM or is it si se is not on the RAM.

You have a 32-bit addressable 4GB, whatever happens to a bone (general public) 32-bit, the IO etc are mapped on top.

So with 2 gb is mapped to the same place except that you do not worry account.

And it serves to send all this without which nothing works, is hyper documented everything

Thank you for the answer

I also wanted to know 2 * 2 GB of RAM to use the 3.2 slowed my pc go or not in the big games??

Hi
I do not know if am having 2 * 2 go then who would win xp pro manages more than 3.2 slowed down my PC.
Would it be faster with 2 * 1 GB of RAM or not
thank you

Yes and no! Having 3.2 GB allows you to have more memory free for any other programs! The system is much more reactive (and dual channel is active although detects only OS 3.2 GB). But rare is the system that require 2GB of RAM for use lambda (for big games today !!!).
