Today I found this.
It shows how to give a powerbook more voltage, and increase the clock.
Nice find. I like their overclock database. Few familiar nicknames there.
Nice. Too bad I don't know how to solder anything.
Cool! If I knew how to solder and how to determine what voltage to change it to, it would be cool to bring my 1.67GHz to 1.92GHz or 2.0GHz. Unless it would render it unusable.
I'll pass, I am on my PB 1.67 HR. It's quite fast and stable, seldom would I hear that the fans kick in, I don't see a need for me to OC it.
Nice find though.
Have the same one. Was thinking the same as you
I just love my PowerBook. I stick with the old apps. I think the old apps works great. For word processing which what the most that I do today, making equipment user's manual, diagnostic manuals and sorts, the old Appleworks is great. Not so graphics heavy and way, way much fluid than Pages or Word for Mac. I don't miss the newer apps at all.
The memory footprint of Leopard is also smaller compared to Lion or ML. For the things I do on this notebook, the horsepower is more than enough. So there is no sense for me overclocking it, with so little to gain except for the bragging rights. I want it cool and quiet.
I attempted this on my 12", but OS X still shows the speed at 1.5 GHz.
I used a pencil to jump two contact points on the rear board, which should have brought the speed to 1.58GHz; could the reason that did not work be that the CPU is the 7447A, and not compatible as it said on macxtrem? I jumped the resistor based on a hunch that it is the MSB_PLL.
The jumped resistor is the grey one to the right.
Does anyone with a 17" have photos of the lobo?
Me personally, I would have to agree with Nameci.. I wouldn't bother.. 1.67 Ghz is fast enough for my needs.. No need to bother with micro soldering.. if Rabidz7 wants to do this let him do it.. but personally, its not going to make a difference.
1.67 to 1.8 is only about 10 percent or less difference.. a PATA SSD would be a much better choice.
Long time no hear.. Has the Mac Pro forum been too much for ya? Welcome back to PowerPC, Dude! I like your iCan avatar..
Still love my cheese grater 6-core.. but love my PPC machines much more.
Agree - the Daystar 2.0Ghz 'upgrade' for the PB 1.67 was fraught with overheating issues so to my mind that more or less proves it's a bad idea. Your main bottleneck on a late G4 is memory bus bandwidth (166Mhz).
You can only do so much on the processor and then you'll be frying it. And even if you reached your theoritical speed, wobegong is right about the bottleneck on the RAM speed. It is lying trying to force a gallon of water on a 3/8" tube. Not so good.
Once again, I have ditched my core 2 duo macbook for my 1.67 PB HR/DLSD. Keyboards are awesome, just awesome, hires screen. For the things that I do in the office the horsepower is just enough.
I am not even using the crap that is MSWord. Appleworks all the way baby, much more fluid and intuitive, minus all the eye candy. Stuff for serious writing.
To the OP just keep the emac, boot it once in a while just to charge the PRAM battery. Who knows it might be iconic someday and you can sell it double of what you bought it.
I've always hung out in both places they're not mutually exclusive
I have a 12" 1,5ghz last revision powerbook and want to overclock it also.
Please post/message me if you succeed.
I still wait for parts so I can do all my planned mods at once.
Meanwhile take a look here, maybe this forum/user can help us.
this guy succeeded overclocking his 1,5ghz 12" to 1,67ghz by just moving some jumpers.
My guess is that you could actually overclock it more if you would solder sth and do sth with voltage.
Why yours still shows 1,5 i do not know but maybe you should have done it to 1,67.
someone commented this on the other forum of your first link:
1.75Ghz wasn't stable anymore and crasht the system. 1.67Ghz works great!
Good luck to all of you who's gonna do it as well
Gamoul! - 30/10/2005
1.75 can't work because it is a decimal multiplier, but you can try 1.83."
hope you succeed soon and I will need some help soon also cause I do not know know yet which jumpers should be moved to where...
