SQL Server 2000 2GB Memory Limit?

SQL Server 2000 SP3 on a Dell dual 2.4GHz Xeon box 3GB RAM Windows 2K
SP4. Two aplication dbs, each less than 2GB in size.

Had a problem where we would run Solomon queries and what not against
the box. It had 2GB RAM, and sqlserv.exe would take up to 1.85GB of
RAM, exhausting the physical RAM on the box. SQL would choke and the
Solomon users would have problems, and I would have to restart the SQL
service.

I added another GB of RAM, bringing the box to 3GB, and increased the
paging file. The OS sees it, and SQL sees it. I check Enterprise
Manager, and tell SQL to dynamically configure memory, and it offers an
upper limit of 3071MB, so it "sees" the 3GB.

I can stress the box with queries to the point that sqlserv.exe takes
1.99GB of memory (as viewed through Task Manager) and then SQL server
chokes. It never goes past 2GB, and the OS and box continue running
fine.

Does SQL server 2000 have some upper limit, or do I just need to change
some setting through EM?

Thanks.
