This check determines whether the min server memory and max server memory settings have been changed in your SQL Server configuration options.
The min server memory configuration option can be used to ensure that SQL Server does not release memory below the configured minimum server memory once that threshold is reached. This configuration option can be set to a specific value based on the size and activity of your SQL Server. If you choose to set this value, set it to a reasonable value to ensure that the operating system does not request too much memory from SQL Server, which can affect SQL Server’s performance.
The max server memory configuration option can be used to specify the maximum amount of memory SQL Server can allocate when it starts and while it runs. This configuration option can be set to a specific value if you know multiple applications are running at the same time as SQL Server and you want to guarantee that these applications have sufficient memory to run. You should also reserve at least 1 GB of RAM for the OS. If you are running other SQL Server components, such as SQL Server Integration Services, you should also take that into account and set a lower max server memory limit.
To configure the min server memory and max server memory settings using the SQL Server Management Studio, take the following steps:
In Object Explorer, right-click a server and select Properties.
Click the Memory node.
Under Server Memory Options, enter the amount you want to use for Minimum server memory and Maximum server memory.
