This is not correct. 

What you need to understand from the warning is that:

   a - your system will use more memory than if you didn't have the warning
   b - your system might run slower than if you didn't have the warning

Your system WILL STILL RUN CORRECTLY.  This is only a performance 
warning, NOT an error.

Please see my other message for clarification.
