Maximum Memory Configurations

What is the maximum amount of memory SQL2K can address per instance using the following configuratio
WIN 2003 32 bit Enterprise Edition OS with 32 GB RA
SQL2K SP3 32 bit Enterprise Edition w/ hot fixe
AWE Enable
/PAE switch in boot.in
Lock pages in memory enabled for MSSQL Service Account
The BOL says SQL2K 32 bit can address up to 8 GB of RAM on Win2K Advanced Server but has no mention of max memory allowed.It is my understanding that each instance will be able to use all of its =addressable RAM. In your scenario you could configure three instances =to use 8GB of RAM and you could have a fourth using 4GB of RAM. That =would allow 4GB of free memory for the OS to work with. Of course you =could install more instances, but you would want to limit the amount of =RAM each uses so that you do not run into problems by trying to allocate =more memory than you have in the server.
