Here’s how you can use T-SQL to set the maximum memory to use. In this example, if the server has more than 4GB of RAM, it reduces SQL Server’s usage by 1GB; if it has less than 4GB, it reduces by 512MB.
DECLARE @ServerProperties TABLE (ID INT, Name sysname, Internal_Value INT, VALUE nvarchar(512)) DECLARE @PhsycialServerMemory INT DECLARE @MaximumMemoryForSql INT INSERT @ServerProperties EXEC xp_msver SELECT @PhsycialServerMemory = Internal_Value FROM @ServerProperties WHERE Name = 'PhysicalMemory' SELECT 'Current Memory Settings' EXEC sp_configure 'max server memory' IF @PhsycialServerMemory > 4096 SET @MaximumMemoryForSql = @PhsycialServerMemory - 1024 ELSE SET @MaximumMemoryForSql = @PhsycialServerMemory - 512 EXEC sp_configure 'Show Advanced Options', 1 Reconfigure EXEC sp_configure 'max server memory', @MaximumMemoryForSql Reconfigure SELECT 'New Memory Settings' EXEC sp_configure 'max server memory'
Hope this helps!
