 ## How to configure memory options using [!INCLUDE[ssManStudioFull](../../includes/ssmanstudiofull-md.md)]  
 Use the two server memory options, **min server memory** and **max server memory**, to reconfigure the amount of memory (in megabytes) managed by the [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] Memory Manager for an instance of [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)]. By default, [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] can change its memory requirements dynamically based on available system resources.
