W2K Memory limit

[Koen W]

I have a windows 2000 server with 2GB physical memory.
There are a lot of small java programs running on this
computer and in my task manager I see that the computer
use 3.6GB memory. Is 4 GB the limit, how far can I go?

By default Windows 2000 server is limited to using 4GB of memory with only 2
being accessible from user space. However, Windows 2000 Server and later
will support up to 64GB of memory when booted using the /PAE flag (see
http://support.microsoft.com/default.aspx?scid=kb;EN-US;268363). I haven't
had any exposure to the 64 bit versions of Windows, but my thinking is that
they would be able to access up to 2^64 bytes of memory.

HTH.

Yes, 4GB is the limit of supported RAM for Win2K Server.
After that you might want to tweak the virtual memory.

Under Win2K Pro & Server, the /PAE flag is used for testing purposes
only. It simply fools device drivers into thinking memory above 4GB is
available on a system, but > 4GB is never actually used. For that you'll
need Advanced Server (supports up to 8GB) or Datacenter (up to 32GB).

Koen,

You can put more than 4095meg on W2K server from an easy workaround.

If the pagefile in under %SystemRoot% right now,
Go to the %SystemRoot% and make two new folders,
and name them pagefile1, and pagefile2.

If you haven't given NTAUTHORITY/system full control of %SystemRoot%
you will need to; just add "SYSTEM" as a user and check all the blocks.
If you need any furthre direction I will be glad to provide it.

After edit regedt32
HKLM\System\CurrentControlSet\Control\Session Manager\Memory Management
d/c PagingFile : REG_MULTI_SZ : c:\ etc.
put this in the box:
c:\pagefile1\pagefile.sys 3000 4000
c:\pagefile2\pagefile.sys 3000 4000

where %SystemRoot% is c: (replace the drive letter appropriately)

restart to to take effect

Huh? Tweak the virtual memory? WTF?

Windows 2000 Pro and Server can "see" 4GB of address space. Both
physical and virtual memory is mapped to this address space. This
means that the 4GB limit applies to the combination of physical
AND virtual memory. No amount of tweaking can overcome this.

If you don't know what you're talking about, and obviously you
don't, then don't respond to queries that are beyond your level
of knowledge.

Exactly.
