 # Configure the index create memory Server Configuration Option
 [!INCLUDE[appliesto-ss-xxxx-xxxx-xxx-md](../../includes/appliesto-ss-xxxx-xxxx-xxx-md.md)]
 
-  This topic describes how to configure the **index create memory** server configuration option in [!INCLUDE[ssCurrent](../../includes/sscurrent-md.md)] by using [!INCLUDE[ssManStudioFull](../../includes/ssmanstudiofull-md.md)] or [!INCLUDE[tsql](../../includes/tsql-md.md)]. The **index create memory** option controls the maximum amount of memory initially allocated for creating indexes. The default value for this option is 0 (self-configuring). If more memory is later needed for index creation and the memory is available, the server will use it; thereby, exceeding the setting of this option. If additional memory is not available, the index creation will continue using the memory already allocated.

 -   When using partitioned tables and indexes, the minimum memory requirements for index creation may increase significantly if there are non-aligned partitioned indexes and a high degree of parallelism. This option controls the total initial amount of memory allocated for all index partitions in a single index creation operation. The query will terminate with an error message if the amount set by this option is less than the minimum required to run the query.

 -   The **index create memory** option is self-configuring and usually works without requiring adjustment. However, if you experience difficulties creating indexes, consider increasing the value of this option from its run value.

+-   Creating an index on a production system is usually an infrequently performed task, often scheduled as a job to execute during off-peak time. Therefore, when creating indexes infrequently and during off-peak time, increasing the **index create memory** can improve the performance of index creation. Keep the **[min memory per query](../../database-engine/configure-windows/configure-the-min-memory-per-query-server-configuration-option.md)** configuration option at a lower number, however, so the index creation job still starts even if all the requested memory is not available.
