 - **VM Committed**: This value shows the overall amount of virtual memory (VM) that SQL Server has committed (in KB). This means that memory used by the process is backed by physical memory or less frequently by page file. The previously reserved memory addresses are now backed by a physical storage; that is they're allocated. If Locked Pages in Memory is enabled, SQL Server uses an alternative method to allocate memory, AWE API and most the memory isn't reflected in this counter. See [Locked Pages Allocated](#Locked Pages Allocated) for those allocations. For more information, see [VirtualAlloc(), MEM_COMMIT](/windows/win32/api/memoryapi/nf-memoryapi-virtualalloc#:~:text=Meaning-,MEM_COMMIT,-0x00001000).
 
-- **Pages Allocated**: This value shows the total number of memory pages that are allocated by SQL Server database engine.
+- **Pages Allocated**: This value represents the amount of memory, in kilobytes (KB), used by the memory pages that are allocated by SQL Server database engine.
 
 - **Locked Pages Allocated**: This value represents the amount of memory, in kilobytes (KB), that SQL Server has allocated and locked in physical RAM using the AWE API. It indicates how much memory SQL Server is actively using and has requested to be kept in memory to optimize performance. By locking pages in memory, SQL Server ensures that critical database pages are readily available and not swapped to disk. For more information, see [Address Windows Extensions (AWE) memory](/sql/relational-databases/memory-management-architecture-guide#address-windows-extensions-awe-memory). A value of zero indicates that the "locked pages in memory" feature is currently disabled and SQL Server uses virtual memory instead. In such a case the VM Committed value would represent the  memory allocated to SQL Server.
