I have an iBook w/ Mac OS X 10.5.8 and 768 MB mem. What should I put as my options on Aticellerator? my preferences now are 209.25mhz Processor and 182.25mhz Memory with AGP Mobility Radeon 9550 graphics.
 
Overclock until it crashes or artifacts, then put it down ~5% and stress test. If pass, keep it, if fail, lower another 5 percent, repeat.
 
What are you using your iBook for? Why the need to overclock the GPU? More ram would help you since you're running Leopard.
 
I'm going to hazard a guess and say that if this is for gaming, your CPU clock speed will be limiting gaming performance. Then quite probably memory before GPU speeds come into play.

I'd say you'd be limited by the VRAM first before anything else, the last rev. PowerBook had 128MB of VRAM while those iBooks still had 32MB.
