Overclocking the PiBoy DMG

Overclocking the PiBoy DMG



Figure 1: The config.txt file showing the location of the overclocking settings.

The Raspberry Pi at the heart of the PiBoy DMG can be easily overclocked for better performance with certain demanding emulators. All that's required is a quick change to some settings in a text file that can be edited on any computer. Continue reading to learn how to overclock your PiBoy.
1. Remove the micro SD card from your PiBoy DMG.
2. Insert the card in to a card reader attached to a computer. Your computer may have a built-in card reader, if not, an external card reader is needed.
3. Using your computer's file browser, open the contents of the SD card. The volume will be labeled "boot".
4. Open the file "config.txt" in a text editor of your choice.
5. Locate the entries "arm_freq" and "v3d_freq". If they are commented out with a "#" character, delete the "#" character. "arm_freq" is the CPU clock speed and "v3d_freq" is the video chipset clock speed.
6. The number following the entires are the clock speed in MHz. These can be set to the desired clock speed by changing them. The maximum frequency for the CPU is 2147 MHz and the maximum for the video chip is 750. Some firmware versions may not work with higher clock speeds, so you may need to experiment. At CPU clock speed of 2000 MHz is the ideal balance of performance and power consumption.
7. Save your changes to the "config.txt" file and safely remove the SD card from your computer.
8. Insert the SD card in to your PiBoy and power it on. Once the system is up and running note the power consumption in the on screen display while idle and while playing games to make sure it's to your liking. If power consumption is too high repeat the above steps but with a lower CPU clock speed.
