Max Memory limit of SQL Server 2005 Standard Edition 32 bit
Hi experts, I have Windows Server 2003 R2 Standard Edition 32 bit with SQL Server 2005 Standard Edition SP2 installed on my production database server.There we have 4 GB RAM in total which is the maximum memory limit of underlying operating system.Recently I figured out there is a memory bottleneck so I am going to upgrade operating system to Windows Server 2003 R2 Enterprise edition 32 bit which can support up to 64 GB RAM enabling PAE (Physical Address Extension)setting on the server as I found on MSDN site. If I have 12 GB RAM in total on the server and there is no application other than SQL Server installed on the machine, what is the maximum memory that can be used by SQL Server 2005 STANDARD EDITION sp2 32 bit ? Thanks, Hemant
Feature comparison says "Memory limited to maximum supported by operating system." [

It is OS maximum. So assuming you get 12GB, you can, in theory, use 12GB although you'd be wise to leave *some* for the OS :)
Use AWE and give the service account the "Lock pages in memory" privilege under Local Security Policy.
To add to @bonskijr's answer - here is a list of memory limits for windows: - [

If I would, I will set the server memory to (keep 2 GB of memory for operating system)-
sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'max server memory', 10240;
GO
RECONFIGURE;
GO
Also you can get better performance by setting the AWE option on. [Enabling AWE Memory in 32 bit Server][1] [1]: http://msdn.microsoft.com/en-us/library/ms190673.aspx
