Increase Computer Speed By Running Windows XP In RAM

If you have more than 1GB RAM then there is no reason that Windows XP should run from page file in hard disk. you can increase the speed of your computer by forcing the windows XP to run from Computer’s RAM (Memory). This one is the best tweak for windows XP I ever found, and it works very well. With this tweak w oue will force windows to load kernel and drivers in memory.

Blazing fast PC

Here is what you have to do :

1) Open the regedit tool (Start -> Run -> regedit.exe )

2) Use the navigation in the left and go to HKEY LOCAL MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

3) Double click the DisablePagingExecutive attribute, and put 1 in the decimal value field
This will make the drivers and the XP kernel run in memory.

4) Double click the LargeSystemCache attribute, and put 1 in the decimal value field
This will improve performance of the kernel

5) Double click the IOPageLockLimit attribute. On some later versions of windows XP that doesn’t exists, so if this is the case you’re done. Otherwise you have to put to the hex value : 4000 for pcs with 128 mb ram, 10000 for 256 mb ram and if you have more put 40000. This value specifies how many bytes can be used for I/O operations in your system.

That’s it, enjoy your faster pc

  1. Will these “tweaks” never die!

    DisablePagingExecutive:
    This setting effects only a small portion of the kernel, which by default will be in RAM virtually all of the time anyway. With 1GB of RAM it will hardley ever be paged out anyway. This setting has NOTHING to do with the pagefile.

    LargeSystemCache:
    This setting does something, but it isn’t good. Microsoft has made it very clear that this is for systems used primarily as servers, in other cases it will almost always impair performance.

    This setting is dangerous with some common hardware confgurations. In some cases users have had to reinstall Windows to restore operation.

    IOPageLockLimit:
    Support for this setting was dropped as of Windows 2000 SP1. It has never been supported on any version of XP or Vista. Forget about it.

    All of this information is avaiable on Microft’s website.

  2. Yet another “viral tweak.” They will never die.

    Back in the days of OS/2 we used to add a line to Autoexec.bat when callers complained about slow boot times. It was “Set FASTBOOT = TRUE.” Every single caller replied that it was booting much faster after adding that bogus line!

  3. I am always looking into stuff on information that I don’t know about. It’s not an easy task to look for things that you don’t know about, because what do you look for? ;) This is right up my alley on something new to me. Great post! Thank you.

  4. I don’t know if this does anything or not, I’ve only ever edited the XP registry on virtual machines.

    I used Nlite to create a Automated XP setup, and installing from it with a lot things disabled and configured Windows XP boots and shuts down faster with it in a Virtual machine than the regular Windows XP on my PC. It adds features like the ability to turn off automatic updates, setup the theme like classic windows 98 along with the task bar the defaults that XP uses for all that takes up memory and load time. Why have all that extra desktop junk if you don’t need it. If when installing windows your not using an Nlited version you are missing out on speed improvements both during setup and after windows has been installed.

    On another note you should have XP Professional and no Home editions never buy any Home editions of windows those are for idiots if you are having problems with Windows 7 you probably don’t have the professional version. More things get fixed in the corporate world of windows because businesses pay money to Microsoft for them to be fixed and fine tuned. Plus the support for them last longer.
