sorry i didn't see your other questions because you edited your post... undervolting doesn't work, smartreflex already does this as far as it can go anyways. you don't have to do that incept stuff again, just open the app and it will work from now on. I suggest increase the speed as much as possible without boosting the voltage. If you didn't get to at least 1175 give it a small voltage boost. Boosting the voltage a lot to get to 1400 is not a good idea.
