Whats the end all limiting factor when overclocking? The highest I can set my EVO to run is about 1190MHz...anything higher, and it gets caught in the boot loop. However, according to setcpu, it looks as if I can theoretically overclock higher than this. Meaning that there is extra room on the slider to increase it. I have also heard of phones getting up to 1500MHz! (I dont know if they are EVO's). So, what is the limiting factor that causes my phone to start becoming unstable at increased MHz speeds? is it the kernel?...the ROM?.......something else?
