I've heard that if u have 1 GIG of RAM u could turn off virtual memory and ur system will run faster
i want to know if this is a good Idea??

  1. Don't turn it off, even with 1GB of RAM. It really won't make the system faster. Many programs are still written so that virtual memory pages must be loaded to the paging file, <i>although</i> WinXP will load this information to the physical memory, instead of using the virtual memory, because of an improved memory manager. That's assuming that at least 512MB of RAM is installed, which certainly applies to you.

    With that much RAM, the paging file will almost never be used, but should remain in place because the OS requires at least 2MB to boot safely, (although memory dumps cannot take place with a paging file this small.)

    Set aside 768MB of space for the paging file, and then just ignore the loss. This way, you won't get any complaints during program installations, while running graphic programs or games, or while starting up the system. The use of the file might never occur, due to the large amount of physical memory, but you'll avoid these issues with it in place. Having the customized, static file will not slow down the system, anymore than removing the file would increase the overall speed. That's an Internet Fallacy, in the same category as $29.95 shareware programs that claim to make hundreds of changes to a system and speed it up to light speeds.

    You'd be much better off if you turned off unnecessary services, killed the bulk of the eye candy, got rid of the items in the prefetch folder, kept the temp folders clean, and did things regularly like checking the disks for errors, and defragging on a reasonable schedule.

    Toey - Can you be more specific - especially the "unnecessary services" and "items in the prefetch folder" that can be gotten rid off ...

    Thanks.

  3. By default, Windows loads many Services that don't need to run for the system to function correctly. Some are even security risks, such as the Messenger service, which has been a major problem for many users over the last few months, due to viruses using the service as a security breach.

    A good website for checking on which services need to run, and which can be customized is this:

    <A HREF="http://www.blkviper.com/WinXP/servicecfg.htm" target="_new">Black Viper Windows XP Home and Pro Service Configurations</A>

    My current Services list looks like this:

    I don't suggest that you set up your system exactly like this ... but use the list as a reference. This works well for me.

    Killing the Task Scheduler stops items from being preloaded into memory from the prefetch folder when Windows starts. Supposedly, this feature is supposed to increase program launch speed, but more often than not, it causes conflicts. Updating drivers or programs can cause problems, as Windows continues to attempt to preload older files. In addition, someone may not want every program used on the computer to be preloaded into memory, regardless of how often the program is used.

    The folder can easily become clogged with hundreds of entries, many of which over time can be outdated.

    I normally just keep the hidden Windows\prefetch folder clean, and avoid unnecessary problems.
