SQL Server 2005 64 Bit Standard Edition Memory

1)Do we really need AWE to get best performance on SQL 2005 x64 bit Standard Edition ?

No. AWE is not required on 64 bit operating system.


2) Can we configure AWE on SQL 2005 x64 bit Standard Edition?

Yes, if the O.S is 32 bit and memory you have is more than 4 GB.

No, if the O.S is 64 bit O.S.

3) Before configuring AWE we need to enabled Lock Pages in Memory Policy,

Can we configure this Policy with SQL Server 2005 64 bit Standard Edition?

Yes, if the O.S is 32 bit and memory you have is more than 4 GB.

SQL Server 2005 Standard edition do not support "Lock Pages in Memory" privileges on the SQL Service account.

Check on the SQL Server ERRORLOG if you get the below message
"Using locked pages for buffer pool". It confirms SQL Server make uses the "Lock Pages in Memory" privileges.


Reference:

SQL Server only uses 2 GB of memory even though the AWE option is enabled
