Mid-05 12" iBook G4/1.33 CPU PLL Resistors?


Well-known member
I have a few of these iBook G4s, and I'd like to take a swing at overclocking them a smidge (or underclocking for better battery life, perhaps?)

I found this forum post from 2010 regarding an 800Mhz iBook G4 overclock, but this model does not have PLL resistors in the same place. Below is a photo of the under-CPU region of one of the boards in question, where I would expect to find such resistors. I have yet to find a schematic for this board, but that would quickly answer the question.
