Overview

The SQL Server is consuming 95% of the server's RAM.

Environment

All SQL Server versions

Detail

 

SQL Server will consume as much memory as you will allow it. By default, that number would encompass 100% of your numerical memory on your machine. 

 

SQL Server will dynamically use memory so even if you set max memory to 12 GB, if SQL requires then it will use memory to a max of 12 GB.

 

The reason for this is that SQL Server cache the data in the database in RAM so that it can access the data faster than it could if it needed to read the data from the disk every time a user needed it.

 

Normally 4 Gigs is allocated to the Operating system (that  depends on the amount of software running on the server)

 

You can specify a Limit in SQL Server Management Studio.

In Left pane tree, right-click on  Server  instance > Go to Properties > Memory.

Here you can specify a Max and Min Limit.
