so i installed v4 yesterday and it is working great, it was running 800mhz for a while, then all of a sudden it goes down to 600mhz. so i reboot the phone and it does the same thing. for whatever reason i cannot go any higher than 600mhz. i am using setCPU and that is what it's saying. anyone know what is going on? is this something normal? i did some quick searching but didn't come up with anything at all.
