Dual 1.2 Ghz PowerMac

[Onyxx]

this is very good news. it means that the new appollo chips do run significantly cooler than the older chips. Did you read that he will "maybe try some thermal paste"!!! the guy isn't even useing any paste and he is achieving a 200mhz overclock. I'm smelling a chip with the capabilities to be overclocked pretty damn high, or maybe those are just the silicon fumes playing with my head

Looks good to me. Lets see him boost that sucker up to 1.4 then we'll see just how efficiant these chips are.

i've got a question!

Beyond overclocking computers does anyone know of any sites that deal with cosmetically altering your mac? i'm talking mostly of the new white ibooks! mine got seriously scratched up and i wanna know what type of customizations are out there to make these things look cool?

1.2ghz is a big ask as it is. My DP1000 was only alive for a few seconds at 1.2 but it is fine at 1067. I know someone else who seems to have killed his DP1000 trying for 1.2 ghz. I will be very surprised if many people have success with a 1.2ghz clock.
Beware the silicon fumes.

How do you know so many people that have this machine? And how do you know so many that have overclocked them? I mean, do you just buy new machine at every release or what?

I think you guys should get that internal water cooling system. Then we will see some serious overclockin.

new tibook ibook over clocking

hey, i have the 667 mz powerbook and i was wondering if there was a safe way to upgrade these to they dont melt or something. Also my friend has an old ibook and i want to get ti to work faster so how do i do that and the same for the new ibook

I buy every new model (really big smile).

With the current single processor models sharing the same heat sink as the DP, there is plenty of headroom for overclocking them.

Putting too much time or money into overclocking doesn't make sense to me. I just wait 3 months or so and the new faster model comes out

I wouldn't recommend it unless you can afford to spend big bucks if it goes wrong.

Laptops have little headroom for overclocking.

That said, it seems that most if not all rev1 400mhz Titanium G4s are capable of running at 500mhz (very easy mod see: http://www.voelker.com/service/void/powerbook/) and it may be that the new 550mhz model will run at 667/133.

A 400mhz rev1 Titanium is quite a nice little bargain when running at 500mhz. We have tried taking a 400 to 550 (I'm an optimist) but it was not stable.

Portable Ovens

When you purchase any portable computer and use it for a long time with the Hard Drive running, it is guaranteed to get very hot. I have a Firewire iBook 466 and it gets rather hot after working with Appleworks on it for hours.

By changing the configuration of the entire motherboard to hoard up a few extra megahertz is all of four things:

(1) It is risky.
(2) It is time consuming.
(3) It is extremely difficult.
(4) It requires the upmost of your patience.

If you are successful, you can go a little faster, but not by a whole lot. If you are unsuccessful, always visualize this message: Congratulations! You have voided your warranty and your Mac is doomed! Please insert 6000 quarters to play again!

If anything, overclock your Mac if absolutely necessary. And don't overclock portables by much because they can overheat and become a portable oven.

By the way, if you are looking to overclock a G3 Powerbook, do not go to far with it. According to my dad, Apple was trying to create a Leather G4 Powerbook (same casing as the Powerbook G3) at 500MHz, but the case melted. (Neat, huh?) This could happen to you if you take one of these portables and overclock them severely.

There is one that has skins for the G3 blue and white forward (anything that is in that style case). You can check them out at http://www.AppleSkinz.com/...I believe that they are working on skins for laptops too. I remember reading at another site about making the same towers side pannels clear so that you can do anything you like to them on the inside and colorize them. You can always take the pannels off, paint them up, or add graphics and then put them back on.

I just hope that Apple does something different for the next generation (not using the Gn label) tower. I know that I would like something that looks different. That way, you can tell just by looking at them that they are different.

Peace

(1)It can be risky but less so if you know what you are doing
(2) Sometimes as little as 10 min's
(3) The rev 1 Titanium 400-500mhz clock requires moving a single resistor
(4) If you get it wrong, definitely.

Some Macs have better overclocking potential than others. The single processor Quicksilver models have excellent potential and can often be taken up to the speed of the model above (eg:800-933) with no problems.
The rev 1 Titanium 400 is probably a 500mhz G4 underclocked to 400. The rev 2 Titanium 550 has the same 133mhz main board (and PC-133 RAM) as the more expensive 667 but is underclocked to 100mhz. The CPU may well also be a 667 but I have yet to confirm this.
Don't overclock a Mac that has not tested stable for several weeks prior.
Don't overclock a Mac if you don't have excellent soldering skills and good eyes. It's better to pay a tech to do the work for you and get it right.
Observe all antistatic precautions. Static can kill your Mac!

Woah! Reading way too much into it... In all likelyhood, since Apple's DP models were introduced, Apple decided to use the same heatsink on the single processor as they do on the dual because its cheaper to build, ship, stock, and install one type of heatsink on all models, than to shave a few centimeters of cheap aluminum and have to maintain a seperate stock, seperate part numbers, blah blah blah.. businesses reuse things all the time to save engineering and overhead costs. I wouldn't assume there was more headroom on the dual just because the single shares the same heatsink.. that could be a very bad assumption.

As for the guy who said he would put Apple Care on his computer and then up the speed because if it blew up Apple Care would take care of it.. Apple Care does not cover modifications made to a computer.. if they smelled an overclock job, I guarantee they would charge every penny as if the policy didn't exist.. It's in their terms of coverage that they don't warantee modified or tampered equipment or upgrades not installed by an authorized Apple Service Center..

As for overclocking itself, I think in moderation it's fine.. I overclocked my iMac 500 to 550 and it's ran for months without problems. I haven't had the balls to try 600 MHz, but hey, 10% gain was 10% gain ya know..

Overclock your iMac G3

Dead on target Xapplimatic... If you compare two or three different G4 towers of the same generation, you will see shared components. It does make good business sense to use as much between the line as possible.

Just as is done in most vehicles. Just like how some SUV's share items with trucks.... it makes more sense to alter them slightly and put different bodies onto them.
