Correct Memory Configuration for 4GB/W2K3 Enterprise

Hello all,
I have a SQL2000 installation with Windows2003 Enterprise and 4 GB of system
memory. SQL never uses more than 2GB of system memory. What is the correct
configuration of the 3GB and PAE switches in the boot.ini file?

From the SQL BOL:
To enable Windows 2000 Advanced Server and Windows 2000 Datacenter Server to
support a 3-GB virtual address space, you must add the /3gb parameter to the
boot.ini file. This allows user applications to address 3 GB of virtual
memory and reserves 1 GB of virtual memory for the operating system.

setting AWE to the amount of memory in the server. You mentioned virtural
memory, I am talking about physical memory.

ry. I think that 2Gb is
for the buffer pool (data cache, cached plans etc), and MemToLeave area is o
utside of that. So,
*possibly* you could tweak out a bit more using PAE and AWE:
Today (roughly):
BP: 1.7 GB
MemToLeave: 0.3 GB
With AWE and PAE:
BP: 2 GB
MemToLeave 0.3 GB
Here's a good place to learn more about how SQL Server uses memory, AWE etc.

Some raid cards (hot swap pci etc) can "steal" some memory unless you use
/PAE.

An application doesn't address memory directly, it goes by the OS memory man
ager. Here's a start:
