What could be the reason for not having further low chi square value (better agreement) in my refinement result?

I have tried every combination of parameter changes and after that i have a poor chi square value. I can't get it lower any further. I know there have been a lot of discussion about Rietveld...

Why CHi^2 is reducing if I divide the intensity by a constant factor?

I was refining my XRD data in FullProf. Highest intensity was 400000. The fitting was good but still the Chi^2 value is very high (0.174E+04) I divided the intensity by some constant factor (say...
