I want to put the /3Gb switch but the AWE switch must be desactivated?

RMQ: in the Best Practice Configurations section you do not specify when AWE switch must be activated.

Follow the instructions at http://searchsqlserver.techtarget.com/tip/Configuring-SQL-Server-memory-settings. You may also want to take a look at the current memory usage using the DBCC MEMORYSTATUS command: http://support.microsoft.com/kb/907877/en-us Vikas,
