Has anyone tried iCook on a ibook 900mhz. It is a program that overclocks the G3 750 fx. I overclocked my computer to 1.1 Ghz but it is unstable. Is this normal? Should i even be using this program?

Advice from people who have used it before would be appreciated.
 
Not worth it

Especially if it is unstable. Overclocking is for geeks who want to take a chance at frying their chips just to get a little bit more power, not for people who like their computers as they are or don't want a broken Mac. You could damage your Mac by using this program to speed it up.
 
I'm all for overclocking if you know what you're doing....but for macs it's a little more sketchy. It's a lot harder to replace a g3/g4/g5 than it is to replace an intel or amd processor.
 
i too would advise against overclocking by 200MHz on a g3 but 100MHz should be fine I am runing my 600MHz ibook at 700MHz with no problems all it dose is that the fan comes on more often I have also overclocked my cube's dual 450MHz g4 to 500MHz with no problems.

you should always overclock in the smallest possible increments and test stability and temperature if possible and as soon as you get a kernal panik freeze ect just take it back one step. (or if you are adventurous you could step the core voltage up but thats what fry's your cpu so dont do that unless you are adding serrious cooling.)
 
overclocking is overrated. i few hundred MHz won't make a huge difference in most applications. but will generate more heat and cause your fan to come on a lot more.
if you want a faster computer, buy more RAM and/or a faster harddrive. that will probably make a bigger difference than a couple hundrend megahertz. and it won't make your machine less stable or run the risk of burning up your processor.
 
dont knock it unless youve tryed it it gives a good FREE poformence boost and my setup is compeatly stable

if it works for a bit at 1100MHz it will be stable at 1000MHz
 
Thanks guys,

I will probably keep it at 1000 mhz when running Halo. The good thing about this app is that when you restart, the overclock disappears so i don't have to worry about turning it off. I have the fastest ibook G3 they ever made so there isn't much i can do to make it faster. I could install a new hard drive but that costs more than it is worth. This was a free 100mhz.

Wrong! But thanks for posting :D

It depends on the "original" speed of the proc and the apps you are using. Going from 600mhz to 800mhz makes a bigger difference than going from 2.0ghz to 2.2ghz. It also depends on the apps you use. For a while I had my P3-800 OC'd to 933 and I didn't notice any speed increase. Of course all I do on that machine is word/internet/e-mail so it's not like I was taxing the CPU to begin with. Now, if I spent all day encoding video, or something like that, then they OC might shaved some time off that.

3 or 4 years ago OC'ing could really get you "something for nothing" but these days it's more about doing it because you enjoy it and not because the extra speed makes a dent in your day-to-day computing tasks.

overclocking can be usefull when you have an expensive cpu and a cheap cpu but if you buy the cheap cpu plus a gaint heatsink/fan watercooling set/peltier combined with some voltage tweaks and you could get the cheap cpu runing at expensive cpu performence at the same temperature with maby just a bit more noise.

the main reason macs are not usually overclocked is beacause they generally require soldering on the cpu daughter card which the average joe cannot handle. However on pc's all you have to do is alter the bios to change the system bus which in turn is multiplyed to make the cpu speed, but on macs there is no such bios controll so you have to change the bus multiple by soldering tiny resistors
