    Physical Memory Limits: Windows Server 2008 R2

    Version Limit on X64 Limit on IA64

    I'm running R2 Enterprise, I was told by Microsoft that this is a limitation in the Hypervisor (Hyper-V/SCVMM) with vmware you do not have this issue.

  • Murat,

    That didn't answer my question at all, I've explained that I already know that max mem is 65536 mb. But why cannot I not go beyond that?

    Thanks,

  • Hi Chicojrman1

    The question is why the max memory for vm has 64 GB limitation.
    With windows 2008 R2 the limitation is 64 gb.
    With Windows 8 Server the limitation increases to 512 GB .

    These are the manufacturer supported and tested configuration.

    Sincerely,
    Murat Demirkiran

  • Hello Chicorjman1,

    These are the limitations of physical memory on physical server right ???

    As you see below, there are also limitations in VMWare too.

    What's New in Performance in VMWare vSphere 5.0

    "Memory Management Enhancements
    1TB vMem support
    In vSphere 5.0, virtual machines can now support vMem up to 1TB. With the new 1TB vMem support, Tier 1
    applications consuming large amounts of memory (> 255GB), such as in-memory databases, can now be
    virtualized. Experimental measurements with memory intensive workloads for virtual machines with up to
    1TB vMem demonstrate similar performance when compared to identical physical configurations."

  • As stated initially i have an HP g6 blade with 127gb of memory with windows server 2008 R2 Enterprise loaded w/ one vm running win svr 2008 R2 Enterprise. I cannot edit the memory beyond 65gb as this is a limitation of the hypervisor in Hyper-v as explained to me by Microsoft.
