If you can't run it faster than 100 MHz, then there may be other timing issues in your design.  Have you created a .sdc file and performed timing analysis?

The numbers in the document don't really matter.  What matters is that your design meets timing requirements for the device, which is what timing analysis is for.  Again, do you have a .sdc file?  Did you perform timing analysis to see what path(s) might be failing timing?
