iBook G4...speedup?

#1 Fri, 23 May 2008 - 04:39 68kMLA

I have an iBook G4 1.07ghz/80gb HD 5400rpm/ 768mb RAM/ Tiger. I'm wondering is there any easy way to overclock it to say 1.2-1.5ghz? I have a utility to keep the fan running at all times. If it can be overclocked, I'd prefer it to be with software. Thanks!

The only software OC I know of was for the IBM G3 FX processor used in the 900mhz ibooks

Why? What do you need your G4 to do that a small over clock is needed?

well I love the game doom 3, i get anywhere from 1-20fps....60 when i stare at a wall in the game. The problem begins when a monster shows up....from a nice 30fps it drops to 5 and it lags so bad. I know its a graphics card problem because this game requires 64mb and my iBook only has 32, but I know that a few extra mhz to the CPU will make it at least 3-10fps faster. Thanks!

Just find a newer iBook G4 logicboard and do the swap

. Unless you know how to overclock with solder.

I have a friend who knows how to overclock with soldering, all I was saying was that I prefer to use software but if its not possible, I guess soldering is the best/only way.

Unless you believe you can overclock by a big enough factor to make the pain and risk worthwhile, I don't recommend doing it. The ibook is one of the biggest PITAs to work on. Given that the BGA problem seems incompletely solved, performing any operations that flex or otherwise put mechanical stress on the motherboard seems ill-advised.

Whatever you decide to do, I wish you good luck!

:?:

First, there's no way you're going to get 1.5GHz out of that CPU, and you would be extremely lucky to get 1.2GHz. I doubt that it's possible.

Second, yes, it will involve soldering, and there's no guarantee of success.

Third, given that the GPU failures are at least in part caused by heat, pumping extra heat into that machine is a really bad idea.

Fourth, given what you say above, why are you even bothering?
