overclocking(rpi v1):

  • arm_freq: Frequency of ARM in MHz. Default 700.
  • core_freq: Frequency of GPU processor core in MHz. It has an impact on ARM performance since it drives L2 cache. Default 250.
  • sdram_freq: Frequency of SDRAM in MHz. Default 400.
  • over_voltage: ARM/GPU core voltage adjust. [-16,8] equates to [0.8 V,1.4 V] with 0.025 V steps. Default is 0 (1.2 V). Values above 6 are only allowed when force_turbo or current_limit_override are specified (which set the warranty bit).

więcej mocy z USB:

I know the following:

  • Setting max_usb_current=1 sets the available current over USB to 1.2A (default is 600mA)
  • This can help if you have a decent power supply (2A, at least) and need to power something like a small external HDD or something that needs 300+ mA.
  • This feature is only available on the B+ and Pi model 2 (at the time of this writing)
