Microsoft Windows Server 2012 Memory Limits

Windows Server 2012 Memory LimitsThe following is a useful summary table that outlines the physical memory limits found with Microsoft Windows Server 2012 (W2K12).  Just as a reminder Windows Server 2012 is only available as an X64 distribution.

Although I’m not a big fan of the new user interface I will be starting to move my virtualization lab based servers over to W2K12 sometime soon.

  1. Hai….

    I’m just asking 1 questions and sharing your experiences

    If I have Windows Server 2012 and its still not license, is Microsoft make any limitation of memory usable ?, because my applications is always use maximum of 4 GB, event the Windows is 64 Bit.

    Thanks in Advance

    • Yes, your application is 32-bit and is therefore limited to the 4GB limit. Use a 64bit version or recompile the application with a 64bit compiler.
