How to Overclock HTC Evo 3D to 1.8GHz

HTC Evo 3D LogoLast time we saw on how you can root your HTC Evo 3D and now we will see on how you can increase the processing speed to a whopping speed of up to 1.8GHz. So, by doing this you can enjoy the status of most fastest Processing Speed phone for your HTC Evo 3D. Though this has been the case with the other devices as some other phones like Samsung Galaxy S2 GT I9100 as well as the Motorola Xoom tablet too has experienced the tweaked increase in the Processing speeds than the printed processing speeds. So, in the due course of this article we will see on how you can increase the processing speed from the default Speed of 1.2GHz to a whopping of up to 1.8 GHz.

If you are thinking that this may spoil the phone then you just go to thin over this thought as many other forums have said that it’s a stable thing and processor behaves in a comfortable manner which is a great news as if processor was unstable at high speeds then it would either get Overheated which could even lead to the bursting of the device but it’s not the case as it successfully gets overclocked without any such danger.

Its highly recommended to proceed if and only if you know what you are doing, please don’t proceed ahead for the instructions if you are a normal user and don’t know anything about the Overclocking as this may even prove fatal for your phone in which case we should not be held responsible for any manner. Also, you are requested to follow the below mentioned procedure strictly as they are mentioned or else you may brick the phone.


Disclaimer: Overclocking your phone is always a risk! Please know what you are doing before trying this. The kernel module is licensed under the GNU GPL and comes with no warranty. The relative safety of overclocking similar ARM processors to such speeds and voltages is generally known, but we can’t be held responsible if you damage your phone with this hack.

Pre Overclocking instructions:

  • Before you proceed, ensure that you have backed up all your contacts, smses, messages and other data which you feel that it’s important as in an unlikely event if all your data gets corrupted then you should be in a position to retrieve all of them back. It has been found many times that this step is just neglected by most of the users but it’s highly recommended to follow this step. It might be time consuming but it will be very useful just in case if you lose the data in your phone.
  • Once done with the backup, you will have to ensure that your phone is left with the charge of at least 50% as anything below that can be a  hazardous thing as the phone might get turned Off in the process of overclocking which is not good and will be then a tedious job to recover the device from there. The more the battery life, the better will be the performance of the phone.
  • After this you will have to ensure that the HTC Evo 3D device is rooted, if the device is not rooted then it might damage the device seriously as all the HTC phones as of now comes with the Boot loaders and to get away with that a temporary root method has been found out which needs to be followed.
  • After checking that the device is rooted successfully, you are ready to proceed for the instructions to overclock the phone up to 1.8GHz. You will have to download the below list of files which are mentioned so that it will be useful for the process of Overclocking.
  • Please note that the appropriate Kernel modes in your phone, if you are not sure about the version then it can be checked at the path of /proc/version where the version will be listed. All you need to find is the local version which will be followed by the version number and will be something like gb7a86da or say gcb1cf83.
  • Just in case if there is any different “ko” version then you will have to edit the same with the below file name using the hex editor, though its bit tricky thing to do but it works. All you need to do is to just replace the “gcb1cf83” with the version which your kernel source has in place.

Procedure to Overclock HTC Evo 3D to 1.8 GHz:

  • Ensuring that you have rooted your HTC Evo 3D phone with the Fre3vo method, you will now be able to run the rooting applications. Please note that just in case if you lose the temp root apps due to the path file /system/bin/su then you will have to re root the device as that means that the root access have been revoked.
  • Now, after this you will have to choose a desired frequency as well as voltage on which you wish to set the phone on, but ensure that it has to be a multiple of 54 MHz. Like if you wish you can set 1512 MHz as it’s a multiple of 54MHz. The maximum will be 1782MHz which is a 54 * 33.

Set CPU Speed

  • After this you will have to push the kernel module into your HTC Evo 3D phone which can be done with the help of the command,

adb push 8x60_oc.ko /data/local/tmp/8x60_oc.ko.

  • With the help of the “SetCPU”, you can set the maximum frequency to 432 MHz and to a minimum of 384 MHz. After this, just go to the home screen and then press the power button and wait till 8-10 seconds as it takes time in loading the kernel with the command which is given below which basically replaces the scpll_l_val with the value you got above and the vdd_uv with the voltage you want (in micro volts). The valid command and the correct one for reaching to 1.8GHz,

adb shell insmod /data/local/tmp/8x60_oc.ko scpll_l_val=33 vdd_uv=1375000

  • Please note that if you don’t specify any parameters then the module defaults to a maximum of 1512 MHz which is nothing but to the 1250000 Micro Volts. Just in case if it crashes down, then you will have to install the kernel again and then reboot to try the same again as since it’s a dual core phone processor, the second core will be active and which doesn’t mean that  it has been over clocked successfully but the settings will be unstable which is a cause of concern.

  • No, again get into the Set CPU after which it will auto detect and will choose the new maximum frequency. All you need to do is to just set the frequency again and then it will be turning into the stable as scpll_l_val and vdd_uv will catch up and will turn on the first core as well.

That’s it, some of the users even claimed that it had clocked to a maximum of around 2GHz as it all depends on the kernel on which you are On. Last but not the least do let us know if you face any issues while overclocking as we will try to solve the issue or fix the problem as soon as possible.
