help about primepower

(asic_designer): no i used switching activity 0.1 to 0.9 then also the percentage of switching power is less.
1)In my design 4000 registers are there and they are consuming most of the total dynamic power. Even if i gave 0 switching activity dynamic power shown by prime power is high and it is mainly internal power..... plz tell me what to do
2) can any one tell me how to apply clock gating in primepower actually i used the command present in the prime power manual
then also no change power.
