SQL Server 2014 Standard, but only 2 GB RAM used

Hello,

I just installed MS SQL Server 2014 Standard Single x64 on a Windows 8 PC. It was bought to replace the Server Express because the RAM limitation of Express.

I set min server memory to 500 MB and max server memory to 28672 MB. PC has 32 GB Ram.

Now I start a very crazy procedure/query that is running for hours.

The problem is now that task manager shows:

- SQL Server Management Studio (32 Bit): 0% CPU and 135,4 MB RAM

- SQL Server Windows NT - 64 Bit: 60% CPU and 2.032,6 MB RAM

If I use: SELECT * FROM sys.dm_os_process_memory  I get:

physical_memory_in_use_kb : 2124632

.....

memory_utilization_percentage : 100

....

So why is there Management Studio 32 Bit if I installed it through MS SQL Server 2014 Standard Single x64 installation?

And much more important: Why is only 2 GB RAM used if 32 GB are there and 28 GB should be used?

kind regards

Peter
