Overclock iPhone and iPod Touch CPU Speed

by Chris on May 12, 2010

As you all know Apple has limited the performance of all processors of our iPhone and iPod Touch. So the processors on the devices are not fully exploited, but with overclocking it is very much possible, but only on jailbroken iPhone firmware. The processor of the iPhone 3G is indeed 600MHz, but Apple has limited it to 412 MHz only likewise for iPhone 3GS instead of 833 MHz it is allowed to operate at 600.

After overclocking iPhone or iPod Touch your iDevice will be faster and more efficient. We stress however that the operation is dangerous and might brick your iPhone too. In order to unlock the functionality, follow our guide to overclock your iPhone.

Steps to Overclock or increase CPU Speed of iPhone and iPod Touch

Step 1. Navigate to System/Library/System/System Configuration/PowerManagement.bundle/

Step 2. You will see a file named “com.apple.SystemPowerProfileDefault.plist”

Step 3. Instead of editing, you are just rename it to “SystemPowerProfileDefaultbak.plist” so the device does not recognize it.

Step 4. Do a reboot and you overclock your iPhone.

Increasing the clock speed would degrade the CPU’s lifespan and is therefore not recommended. Do at your own risk. We will not be held responsible for bricking your iPhone or iPod Touch.

    The true way to overclock is to edit the fstab file in /Private/etc. This is where you can manually set the clock speeds for when your iphone is in sleep mode and while you use it.

      I hate people who pick on newbies and try to destroy their devices.  fstab is the filesystem pointer (“tab”) file, and changing one byte of it will prevent your device from booting and most likely require a full restore to fix.

        Your comment is entirely incorrect. Not only is my iPhone 3G is clocked at 600mhz while editing the Fstab file and some .Plist files. But I’m running WD 5.1 as well. You may know what the fstab file is for, you still don’t know what the f.u.c.k you are talking about.

        • Levi Cowan

          thank you StanTek. I’ve got my iPod 4g clocked to 1GHz (200 MHz over apple’s config) and I’m going higher. the ARM Cortex-A8 manufacturer’s site says it can go higher than 1 GHz

          • Pingas

            I’m running my iPod touch 4th gen at 1.2 GHz with virtual ram. :P

      • android kicks your ass

        I used fstab to overclock my ipod touch 2g to 700mhz, I love it!

      Rastermany is an A.S.S. Editing this file will render your device unbootable. Nerds like him should G.A.F.L. and stop picking on unsuspecting users.

    hej

    my iphone clock reports 412 mhz however my iphone does appear to run 50 times better after the hack my iphone is full 16gb of info eventhough ur clock dosent report it u’ll notice it if u had a filled device ……

  • Pez_Hater

    Go to the terminal or SSH to the device and type sysctl hw.cpufrequency and see what it reports. My iPhone 3g still reports 412 frequency. I don’t think this works at all. No changes in the benchmarks and the terminal still reports the same clock speed.

  • Pez

    I wouldnt do it, all it does is just tell the iphone to ignore the power management feature which means it will always run at the default clock speed even in sleep mode so your just wasting battery.

    There is however a proper way to overclock the cpu where you actually put in your own clock speeds.

    • Chris

      Ok, how do you enter in your own clock speeds?

    • Pez_Hater

      OK FUCKER if you are so smart then how do we do it………….That is what I thought, you are full of shit.

    • Tjliverpool

      Can you tell us how?

    • ENMAR68

      So Pez…can you tell us how to put in our own clock speeds?

  • Alexandru_q

    doesn’t work.all bullshit….

  • matt

    okay i am in the com.apple.SystemPowerProfileDefaults.plist so what do i have to change to increase the cpu? right now i am running at 532MHz, i am using a ipod touch 2g 4.0 jailbroken

    This doesn't work.
    CPU Clock Speed is a hardware setting.
    NOT in a configuration file.

    Renaming or editing this file has absolutely no effect.
    If you don't believe me, do a CPU benchmark before and after you rename the file.

    Or even better, use SysInfoPlus to see that the CPU speed is still the exact same.

    • Apple Loves you

      Actually you can. From iOS 2.0 to 2.1 apple overclocked the iphone from 400 Mhz to 412

    • ass

      The processor runs 200 mhz underclocked for batterylife

    is it true that iphone 4G will be release on july ?
