It's time to overclock 2G, 3G iPhone

    Since iPhone 3GS has 600Mhz CPU and 256 RAM, it's matter time when developers will make apps for 3GS spec which means slow games/apps for us 2G, 3G users. I can see some games will be super slow and some apps will not run properly on puny 412Mhz. Maybe least we can do is to overclock(or de-underclock) it to 612Mhz so we can expend our phone's life a little bit.. Is there a way to actually do this?? Do you think it's hardcoded? :mad:

    a 200mhz overclock on a cellphone CPU will most certainly fry your phone.

    Even if you could overclock it by 200Mhz, it wouldn't be as fast as the 600Mhz Cortex-A8, and the GPU still wouldn't support OpenGL ES 2.0.

    Overclocking it will just make it really hot and drain the battery.

    Im sure most developers wont make apps exclusive for the 3Gs' specs, if they did they would be seriously limiting their market and that would be bad for their business. They will probably make apps that work for 3G but they will run better on the 3Gs. For example, The Sims probably wont crash at all anymore on the 3Gs:p

    An 200 mhz cpu overclock would certainly put massive amounts of cellular radiation into your brain and cook you from inside out.... But anything for better games!!! ;)

    Totally agree. But all I want is the option to overclock ONLY while it's attached to a charger, that way I won't forget to turn it off and have it run out when I get to uni.

    But it'll have to happen eventually. Two years in the tech industry is pushing it, especially when your are a company like Apple who is constantly trying to push the envelope. I bet futureproofing probably delayed the iPhone from the market by atleast a few years, especially considering considering the screen and multi-touch. I'll give a little bit of leway to first gen owners such as myself but come 2010, it'll be a little unreasonable for customers to expect a three year old phone to scream on every program available. You won't be able to please anyone in this arena, because one camp will say "oh the iphone's graphics are lame its not really a gaming device" while the other camp is saying "customers are complaining that their 3-4 year old devices aren't running the latest games while the previous two iphones have SLI graphics and 2 gigs of video ram available!"

    The processor in the iPhone/iPhone 3G and 1st gen iPod Touch are underclocked to 412MHz. So, essentially, you're not really "overclocking" the processor since it never really was clocked to its native speed to begin with.

    I can vision the current ARM processor bumped to 600MHz to result in a significant decrease in battery life and possibly cause other internal timing/bottleneck-related issues. I'm beginning to wonder if the real problem with slow transitions and framerate isn't with processor speed, but rather the performance of the GPU.

    Apple push the envelope on technology?

    Not in a while my friend, not in a while...

    I have to disagree with you here. I currently own a g1. Originally clocked at 254mhz and is now overclocked to 528mhz and working on 715mhz. So its deffinatly possible! Especially with a linux based firmware it should be fairly simple.

    Uh, you are completely full of **** sir. I say I want to see proof of this.

    umm considering that the CPU is not the antena not going to cause that problem.

    Now heat would be a problem. the 200 Mhz over clock is just under a 50% over clock. That will easily overload the heat sink and fry the chip.

    Sure, go ahead. See what happens to your battery life.

    Proof. I have 2 G1's and the dev community for it far exceeds this place. We wanted to clock our processors to there full potential, so it was done. Everyone here just bitches and moans about it, we aren't trying to overclock the iPhone, just set it to what its capable of. And with a name like MasterDev you should have known how easy it was to tweek the G1, or atleast Google it and see if it was done already instead of making yourself look uninformed. Woah look here is a app that does it automatically without any coding knowledge.

    First university coding class = 47 years ago
    Several years ago, I had a Samsung i730 WM smartphone, which normally ran around 520MHz. With a third party utility, I set it to overclock to 700MHz when it needed to do a lot of work, and otherwise to go very slow. It got flaky though if left too high, too long.

    As for the iPhone, people found generic specs off Samsung's website for certain chipset families, and reported the highest numbers they found... whether or not they have any meaning for the actual chip that Apple used.

    Since Apple custom marked each chip, we cannot know for sure what they were really rated at.

    One thing for sure, it's a lot cheaper to take the batch that only tested to 412MHz. Why pay for the extra testing and rejects at 600MHz unless you have to?

    Yeah that's one downside....with my PSP being overclocked from 133mhz to 333mhz (there was an option for 366, oh god) I had about 3 hour battery life...God knows what an iPhones battery life would be like...I would imagine about 1:30 in airplane mode no joke.

    This is retarded. HTC Dreams are clocked at 528mhz out of the box.

    Well, i remember the old OC'ing days, so opened up my iPhone, pulled our a #2 pencil, but couldnt find the dots to connect on the processor, now I got a brick...
