I have a rooted mytouch 3g with CM6RC2. I installed SetCPU and autodetected frequencies. The max it will run at is 576Mhz. I created a setcpu.txt file with the same frequencies it autodetected, but also added a few more with higher frequencies, however setcpu won't run past 576Mhz. Is this the highest I can go or do I need to input specific frequencies in the setcpu.txt file?
