Windows XP 32 bit – Fix the situation of not getting 4GB of RAM


By default, Windows XP 32 bit will not be able to receive up to 3.5 GB of RAM. But there is no way for it to get enough 4GB, instructions on how to upgrade Windows XP 32 bit to get 4GB RAM easily. This is due to the 32 Bit OS limitation, but not without the way to handle Windows does not get enough of this ram


You have a new PC with 4 GB of RAM, but if you are too familiar with the Windows XP interface, or have a lot of software installed on 32-bit Windows XP, you do not want to install win 64 or wins 7.

By default, Windows 32bit will only receive a maximum of 3.5 GB of Ram and usually 64-bit versions will receive enough RAM (64 bits support up to 128 GB Ram). This is very normal, because the principle of Computer Science: The fewer bits are, the less the ability to process and store addresses, so 32 bit OS receives less RAM than 64 bits is normal. .

However, the option to install 64-bit version is still optimal with windows 7 but probably not a good choice with Windows XP. If you only want to upgrade (buy additional RAM to plug in) For some reason you do not want to install win 64 bit or do not want to reinstall takes time, you can follow a few simple steps below that will help you. waste your RAM.

Note: We show you how to handle boot.ini.In addition, if you do not like working with boot.ini file or can’t find boot.ini file, you can use Enable DEP to fix RAM receiving status of Windows XP 32 bit

Step 1: Please copy a backup of C: boot.ini just in case something goes wrong.

Step 2: Use Notepad, or any Editor to open the file C: boot.ini, edit the Boot.ini file with the following content:

[boot loader]
timeout = 30

[operating systems]
multi (0) disk (0) rdisk (0) partition (1) WINDOWS = “Microsoft Windows XP” / fastdetect /PAE

At first when you install it only receives ~ 3.42G Ram, add one / PAE then I can go up to 4GB.

Step 3: Reboot the computer

/ PAE was Physical Address Extension, allows most 32-bit operating systems to be able to receive equal to or more than 4GB of RAM.

For example:

multi (0) disk (0) rdisk (0) partition (1) WINDOWS = “Windo ws Server 2003, Enterprise” / fastdetect /pae

Bootcfg command

bootcfg / raw “/pae“/ A / ID 1

Windows Server 2003, Datacenter Edition and Windows Server 2003 SP1, Enterprise Edition: 64 Gb
Windows Server 2003 SP1, Datacenter Edition: 128 Gb

Note: Only 32-bit operating systems support PAE, 64-bit operating systems do not support.

In addition to configuring to receive RAM via PAE parameters, you can also learn more parameters of boot.ini, there will be interesting things such as:
