I have heard that after the Optimus's processor is overclocked to a stable clock speed, it will become "accustomed" to that specific clock speed after a period of time. So, the processor can be overclocked even further after this period of undisclosed time has passed whereas beforehand it would have been unstable.
For example, I were to set the Optimus's clock speed to 748 Mhz in the beginning because the phone would occasionally crash at anything higher. After, say, a few weeks have passed, is it possible to clock it up further to 767 Mhz and then after that clock speed has been used for a long duration, clock it up still further. (I'm sure there is a limit to this if it is true, though.)
