Forcing Windows XP X32 To Use 4GIG of Ram - March 2012

This is new method to GET forced to apply 4GB RAm to your 32bit Windowns :) , Just follow the instructions below to Force unlocking it & Try it at your own Risk :)

The range of integer values that can be stored in 32 bits is 0 through 4,294,967,295 or ?2,147,483,648 through 2,147,483,647 using two's complement encoding. Hence, a processor with 32-bit memory addresses can directly access 4 Gigs of byte-addressable memory.

However, it is not a waste, there is a function called PAE (Physical Address Extension) which will, in a nutshell, tell your cpu to use all 4 gigs, while your os will continue to detect that you're using say 3.2 gigs of RAM. to enable PAE, you need to put : /PAE

Here is how the boot.ini file looks >>BEFORE<< timeout="30" default="multi(0)disk(0)rdisk(0..." noexecute="optin">>AFTER<< you edit it:
*-----------------------------...

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0...
[operating systems]
multi(0)disk(0)rdisk(0)partiti... Windows XP Professional" /noexecute=optin /fastdetect /usepmtimer /PAE
Note: That you must be careful NOT to change anything ELSE, just add the /PAE to the last line exactly as I have
shown you.
