We wanted to change the memory setting for a SQL Server Instance on a particular server. The settings for the way our SQL Server 2008 Instance uses memory was set to minimum 0 to maximum 10GB so we changed it to minimum 5GB to maximum 10GB. When the Sys Admin monitored this server after making the change it was not using minimum 5GB. We did not restart the SQL Server 2008 services or reboot the server after making the SQL Server 2008 memory change. Why isn't grabbing and holding the minimum of 5GB?
