What makes you think that you need to do this? Did an application
vendor tell you to do this?

Well, Xp is by default to use only 2gb of memory. And if you have any more
the system basicly wont use it.

Or look for micrsofts knowlage base, or google it for more info.

No, you misunderstand the use of the /3GB switch (also called 4GT RAM
Tuning). Do not use this switch unless specifically instructed to do so
by an application vendor. Explaining the use of this switch is a long
story, and understaning the use of the switch requires that you
understand advanced Virtual Memory management concepts and Virtual
Memory Address Space, these are not the same thing as physical RAM. If
you feel up to it you can read about it in these links:

Hi,

No you don't! That web page is wrong. The /3GB switch controls how the
4GB virtual memory space given to each process is divided. DON'T use
it unless the manufacturer of one of your programs has told that the
program needs it. It has nothing at all to do with physical RAM.

Now when i enable the 3gb switch i get series of event errors and explorer
hangs and almost everything doesnt work on xp.

So remove the switch! You won't be able to see all 4GB, there's no way
around that. See http://members.cox.net/slatteryt/RAM.html for an
explanation.

reasons Thanks .

Please Help,

You are depriving the OS of virtual address space. The 4 GB of virtual
address space allots 2GB for the applications and 2GB for the OS. The
OS 2GB also contains the hardware addressing space which may be
up to 1GB, giving the OS little to operate in. Try adding
/userva=2500 to your boot.ini line after the /3GB switch. That will give
2.5GB to apps and an extra 500MB to the OS. If it works you can
increase it in 100MB steps until you have problems, then back it off
by 100MB.
