The psp was downclocked to 266 Mhz to save battery life. Homebrewers found a way to clock it back to its original intended 333Mhz. Would it be a problem to actually overclock the processor beyond the standard 333Mhz? I know the processor would heat up a little more and eat up more battery, but what would occur if you actually did it?

i dont know what it would do but i think it wouldnt like break it or anything like u said

It would'nt, it would just cause futher stress to the internal battery and cause the owner to purchase a new battery...
there isnt much point unless you play from the charger, and i never think they wont make beyond the max Mhz which is 333mhz.

What is it exactly that you wish to achieve from this?

First I would love to see you even attempted to overclock it. What would you use? It will be harder then overclocking your CPU in your desktop.

It was just a thought. I was thinking maybe there was some sort of application for it. For example, some emulators. They may not run some games at full speed on 333mhz, but why not try upping the processor speed to make up for it. You never know, something might just come along and a little extra power from the processor might help.
