How to Change CPU Speed on iR Shell

Though the Sony PSP is an effective handheld in its own right, using home-brew software on an "unlocked" or "hacked" system can enable greater functionality. IR Shell is software designed to replace the standard PSP interface, the XrossMediaBar (XMB). It is geared toward power users, who are able to work with a less structured home menu that performs actions in fewer button presses. Additionally, iR Shell enables several features missing from the XMB, such as multitasking, infrared code transmission, navigation of storage devices, and control of the system's CPU speed. By changing CPU speed, you may designate your preferred balance between processing power and battery consumption.

Instructions

- 1
  Boot your PSP and run iR Shell from the game menu. This is only necessary if IR Shell is not already configured to run automatically.
- 2
  Navigate to the CPU icon from the iR Shell main menu. The appearance of the icon may vary depending on the display theme you have chosen, but it will always be located on the fifth column and second row, beginning from the bottom-left corner. The default icon depicts a microprocessor.
- 3
  Press the X button on the icon to cycle through various CPU speeds. By default, the PSP is set at 222 MHz. Each press takes you to the next highest setting until you reach the upper limit, after which you begin from the lowest setting. Starting from default, one press will take you to 266 MHz, two to 333 MHz, three to 100 MHz, and four puts you back where you began, at 222 MHz.

  Choose the speed most appropriate for the task at hand. For example, if you are using your system as an MP3 player, you could lower the speed to 100 MHz to save power. If you want to play a game and listen to music at the same time, you could increase your speed to 266 or 333 MHz to ensure that your game and music player can function simultaneously without any loss of performance.
