SQL SERVER – Running 64 bit SQL SERVER 2005 on 32 bit Operating System

A few days ago, I have received an email from users asking questions: How to run 64 bit SQL SERVER 2005 on a 32-bit operating system?

SQL SERVER - Running 64 bit SQL SERVER 2005 on 32 bit Operating System 64-bit-800x238

NO. It is not possible. 64 bit SQL Server can not run on a 32-bit operating system.

It is truly another way. SQL Server 32 bit can run on a 64-bit operating system.

Read additional documentation on 64-bit Computing with SQL Server 2005

  • Can you give some info about the reverse? running 32-bit SQL Server on 64-bit OS?

  • Pinal,
    If I run 32-bit sql on 64-bit environment, I have learnt that the 32-bit tools run in the WOW environment and hurts performance. The question is: will AWE have to be enabled to address memory over 4gb since the sql server is 32-bit? I realize 64-bit doesn’t have the limitation but will 32-bit sql address that memory over 4gb without awe. I believe it wont but I’d like to get a confirmation.

    thanks for your time.
