As per SQL Server Books Online topic "Managing AWE Memory"  
  
Use System Monitor (Performance Monitor in Microsoft Windows NT® 4.0) to retrieve information on SQL Server memory usage and available memory.  
  
Task Manager does not provide accurate memory usage  
  
information for AWE.  
  
Therefore, the memory quoted for sqlservr.exe is NOT correct.  
  
To obtain the correct amount of SQL Server memory usage, you can use the Total Server Memory (KB) performance counter,  
  
activated through System Monitor, or select the memory usage from sysperfinfo.  
  
For more information, see Monitoring Memory Usage.  
  
Also, make sure that the MSSQLServer service account has been assigned the "Lock Pages in Memory" privilege on both nodes.
