How can we let SQL Server 2005 X86 recognize and use RAM greater than 4GB

  • I have a windwos server 2003 R2(64bit) installed SQL Server 2005 X86 Standard Edition .

    I have enabled AWE(as screenshot), and restarted windows server, but when I ran SQL Server (even if I ran the complicated computation). system can't use the RAM greater than 4GB.  because as some reason we can't upgrade SQL server from 2005 to 2008 or other higher version ?

    How can we let SQL Server 2005 X86 recognize and use RAM greater than 4GB ?  thanks!

    if we use a 64x to register SQL server ,can SQL server be upgraded from 32bit to 64bit ?

  • I'm going to be as honest as possible. I don't remember how 2005 works any more.

    However, yes, you absolutely can upgrade SQL Server to 64bit on 2005. Doing so changes memory configurations and should have no trouble using all the memory. Just disable the /3GB switch, it causes problems on a 64 bit OS.

    Beyond that, hopefully someone around still has active knowledge of this 16 year old software.

  • You can only upgrade 2 versions.   So, 2005 you can do an in-place upgrade to 2008 or 2008 R2.

    BUT, guess what.  2008 and 2008 r2 are also no longer supported.

    I have a 2005 box that I need to keep alive. What's preventing you from upgrading?

    Dear Michael L John,

    as there is an ERP system, but nobody knows how to  do the configuration if we  upgrade SQL Server 2008 or 2008 R2

  • There is a discussion on what you can do at https://github.com/SQL-FineBuild/Common/wiki/SQL-Server-Memory-Management

    The SQL db engine can be given access to more than 4gb memory via AWE even if itcannot address it directly. All other components (SSAS etc) are limited to 4gb and must share that memory with everything else that is running.
