![]() However, you can set the memory options manually and restrict the amount of memory that SQL Server can access. ![]() The max server memory option does not limit a remaining unreserved memory area that SQL Server leaves for allocations of other components such as extended stored procedures, COM objects, non-shared DLLs and EXEs. ![]() The max server memory option only limits the size of the SQL Server buffer pool. It isn't recommended to set max server memory (MB) and min server memory (MB) to be the same value, or near the same values.For more information, see Database Engine Service Startup Options. If you can't start SQL Server after changing this option, start it using the -f startup option and reset max server memory (MB) to its previous value. Setting max server memory (MB) to the minimum value can even prevent SQL Server from starting.However, setting max server memory (MB) too low is a lost performance opportunity, and could cause memory pressure and performance problems in the SQL Server instance.Setting max server memory (MB) 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.For more information, see dynamic memory management. Within these bounds, SQL Server can change its memory requirements dynamically based on available system resources. For more detailed recommendations, see max server memory. ![]() The default settings and minimum allowable values for these options are: Optionħ5% of available system memory not consumed by other processes, including other instances.
