Memory usage

We have about 40 SQL Servers in our environment, and none of them use 2 GB of
RAM - in fact they all use between 1.6 and 1.7 GB.
Our configuration option is set to dynamically use memory - and our
databases are as large as 100GB.
Any ideas?How much physical RAM is in the machines?

And have you used the /3gb start up parameter on the boxes with 4GB?
What you are reading is about right for the 3GB boxes -2Gb for SQL, 1GB for
the OS. The /3GB option will give SQL Server 3GB on the boxes with 4GB
memory.

What version of SQL server and Windows are you running? Standard SQL
server 2000 is limited to 2GB and in real life it's normally using max
~1,8 GB.

MemToLeave portion of memory. So if you are using Task Manager to view
memory usage it looks like SQL Server only uses about 1.7GB and this is
normal.

Windows 2000 Server.
It is possible configure SQL 2000 Standard to use 3 GB?
