[Q] cpu frequency automatically set to 800 mhz while overclocking cpu.

Set cpu or any other cpu application automatically set my cpu at 800mhz while i set 1400mhz max. And 1200mhz min. In ondemand governor or any other governor.
When i set any criteria of frequeny in which minimum mhz is higher than 800 mhz than it comes down to 800 mhz and stays there .Why ?

I tried set cpu,no frills cpu,cpu adjuster,rom toolbox lite.one by one i tried each app but problem is same in each case :/
