/3GB Flag Added but no result

[Guest]

Hi

We are testing a SQL Server Enterprise Server on a Windows 2000 Server that has 4GB Ram.
We added the /3GB Flag to the boot.ini and rebooted the Windows 2000 Server. The task manager shows a maximal use of 1967556. It seems the the operating system is still using 2GB of Ram and not the desired 1GB.

Slowly baffled. Can someone please bring light into this subject.

Thanks in advance

Perhaps you need to use the /USERVA=3030 switch as well?

"The use of the /3GB switch from the Boot.ini file with Windows 2000
Professional or with Windows 2000 Server can give the appearance
of a 3 GB range of user-mode memory. However, the memory from
0x80000000 through 0xBFFFFFFF is not usable."

In the Win2K product line, the /3GB option is only functional in
Advanced Server and Datacenter.
