Indeed was to agressive, but only for the highest frequencies.... This is the table (i hope) most stable so far.

Not so undervolted at higher frequencies but still saving some juice and heat at the lowest. Btw great kernel kamma and thx for implementing this feature in it, it´s awesome.

Are u planning to release a new one soon?

I´ve been stressing the CPU in almost every frequency and so far so good.... i cross my fingers... :P
