The 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.
| Windows Server 2012 Version | Physical Memory Limit |
| Foundation | 32GB |
| Essentials | 64GB |
| Standard | 4TB |
| Datacenter | 4TB |
| Storage Server 2012 Workgroup | 32GB |
| Storage Server 2012 Standard | 4TB |
| Hyper-V Server 2012 | 4TB |
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.
