I have a server with 8GB physical memory, and I wanted to expand the memory from 2GB(default) to 6GB using AWE, so I did this: 1. added /PAE in boot.ini 2. sp_configure 'show advanced options', 1 RECONFIGURE GO sp_configure 'awe enabled', 1 RECONFIGURE GO sp_configure 'max server memory', 6144 RECONFIGURE with override GO 3. shut down and restarted SQL Server When I run exec sp_configure 'max server memory (MB)' It returns - Name Min Max Configure_value Run_value max server memory (MB)421474836476144 6144 And, it appears that Max server memory is still 2GB rather than 6GB that I requested. However, Configure and Run values are all 6GB. What do these two value mean? Should Max show 6GB instead of 2147483647. What did I do wrong in this setting? Any input would be greatly appreciated. Thank you very much.
