However, after memory usage has reached this value due to client load, SQL Server cannot free memory unless the value of min server memory is reduced. SQL Server will not immediately allocate the amount of memory specified in min server memory on startup. Use min_server_memory to guarantee a minimum amount of memory available to the SQL Server Memory Manager for an instance of SQL Server. These settings take effect immediately without a server restart. If you are using the sp_configure system stored procedure to change these settings, you can change them only when show advanced options is set to 1. The min server memory and max server memory options are advanced options. This method is useful for system or database administrators to configure an instance of SQL Server in conjunction with the memory requirements of other applications, or other instances of SQL Server that run on the same host. The server options min server memory and max server memory can be set to span a range of memory values.

This difference is the maximum amount of memory you can assign to the current SQL Server instance. Before you set the amount of memory for SQL Server, determine the appropriate memory setting by subtracting, from the total physical memory, the memory required for the OS, memory allocations not controlled by the max_server_memory setting, and any other instances of SQL Server (and other system uses, if the computer is not wholly dedicated to SQL Server). SQL Server can use memory dynamically however, you can set the memory options manually and restrict the amount of memory that SQL Server can access.

For more information, see Database Engine Service Startup Options. If you cannot start SQL Server after changing this option, start it using the -f startup option and reset max server memory to its previous value. Setting max server memory to the minimum value can even prevent SQL Server from starting. However, setting this value too low could cause significant memory pressure and performance problems. Setting max server memory value too high can cause a single instance of SQL Server to compete for memory with other SQL Server instances hosted on the same host.
