Pocket Hack Master speed configuration guide

by Anton Tomov on Aug 21

Speed settings are an essential part of Pocket Hack Master's successful configuration. A speed setting is a set of parameters used to fully describe a unique combination of CPU, memory, display and other peripheral clocks.


Different processor families have different set of parameters. In our example we will be configuring a device with an Intel XScale Bulverde PXA270 processor. The Speed configuration module of Pocket Hack Master is used to configure the speed settings.


In this guide I will show you how to configure the speed settings in Pocket Hack Master.


importantIt is highly recommended to fully backup your device before configuring Pocket Hack Master speed settings. A full backup will take less than 5 minutes and will help you restore your device in case you attempt to apply a speed setting that is not stable. In case your device locks up during speed configuration try a soft reset. If that does not help your only option will be restoring from the backup.


Start Pocket Hack Master. Launch the Speed configuration module: 


Start the Speed configuration module


Inside the Speed configuration module you will see the default list of suggested speed settings for your processor:


Speed configuration module


Each entry in the list represents a CPU speed setting. The first column shows the CPU speed for the given speed setting in MHz, a check box used for selection and a status icon. Below is a description of the possible icons:


Unknown speedUnknown. The speed setting has not been tested yet. 

Stable speed Stable speed. The speed setting has passed the stability tests.

Unstable speed Unstable speed. The speed setting has failed the stability tests and cannot be used.

Favorite speed Favorite speed. The speed setting has passed the stability tests and has been configured as favorite.


Pocket Hack Master requires each speed setting to be tested before it can be actually used. Testing includes burn-in CPU stress tests and a number of benchmarks.


There are two reasons for that requirement - one is to guarantee that the speed setting will not cause a lock up when used and the other is to determine the performance of the speed setting. Pocket Hack Master benchmarks the overall CPU integer performance (MIPS index in the table) and the RAM performance (Memory index in the table) for each tested speed. The combined index from those two benchmarks is called combined Speed Index (SI index in the table). The higher the SI value of a speed setting is the faster the device will be when the speed setting is applied. The Scaling module of Pocket Hack Master uses the SI values to determine which speed setting to use.


The remaining columns are CPU specific. In our example the columns describe the parameters of an Intel XScale Bulverde PXA270 speed setting:


  • Bus - the bus clock in MHz. Bus speed has great impact on the overall device performance. When possible avoid using speed settings with different bus speeds as this introduces additional stress on all peripherals of the device.
  • RAM - the RAM clock in MHz. The greater the RAM clock the faster your device will be. RAM clock has higher impact on the overall device performance than the CPU clock. Increasing the RAM clock by just 10% will make your device much faster than increasing the CPU clock by 20% for example.
  • LCD - the LCD clock in MHz.

Choose the speed settings you wish to test by checking their check boxes:


Select speed settings to test


Tap Test to instruct Pocket Hack Master to test all selected speed settings:


Tap Test to start the stability tests 


TipLeave your device on A/C power while running the tests and disconnect it from your desktop computer in order to achieve maximum accuracy in the tests. Do not touch the touch screen or press any hardware buttons while the tests are running. If the device locks up during the stability tests perform a soft reset and restart the application - Pocket Hack Master will remember the speed setting that caused the lock up.


After the tests are complete you will be returned to the Speed configuration dialog and all speeds that passed the tests successfully will change their icon:


Tested speeds will change their icon



In case you experience too many lock ups even with the default speed for your device (in our case the 624MHz setting), try disabling the device built-in scaling to see if that will improve stability. To do that, close the Speed configuration module to return to the main Pocket Hack Master launcher. Tap the Edit menu, then choose Settings and navigate to the Advanced panel. Check the check box saying Disable built-in scaling:


Disable built-in scaling

TipMany device manufactures include a simple form of scaling in their devices to improve battery performance. Unfortunately the built-in OEM scaling often conflicts with Pocket Hack Master and causes lock ups. Only disable built-in scaling if that improves the stability of Pocket Hack Master. Selecting the option to disable built-in scaling when there isn't a conflict between Pocket Hack Master and the OS will only consume more power and therefore shorten battery life.


After you have tested the speed settings you wish to use in Pocket Hack Master you need to "tell" Pocket Hack Master which ones you would like to actually use. To do that you have to mark these speed settings as "favorites". Use the stylus and tap and hold on the desired speed setting until a context menu opens up. Choose Favorite then Set:


Set favorite speeds


Note how the speed setting changed its icon to a yellow start (meaning it is a favorite speed now):


Set favorite speeds


Proceed and mark the remaining tested speeds as favorites as well:


Set favorite speeds


Only speed settings that passed the stability tests can be marked as favorites. Even if a speed setting passed the stability test it won't be available to the remaining Pocket Hack Master modules and therefore you won't be able to use it unless you mark it as favorite.


Now the configuration of the Pocket Hack Master speed settings should be complete. You can test more speeds or change the favorites any time you want by running the Speed configuration module again. In my next guide I will show you how to use advanced speed configuration techniques and also will give you some hints on how to configure specific processor families.

Mr. Tomov:

I finally found the energy and time to run the speed test and I have submitted my results. I am running the test a second time to check my results, but I followed your instructions to the letter. I hope they are helpful. I love Wizcode and wish you had 100 products in your library smile
