## Raspberry Pi Configuration Settings
##
## Revision 14, 2012/10/22
##
## Details taken from the eLinux wiki
## For up-to-date information please refer to wiki page.
##
## Wiki Location : http://elinux.org/RPi_config.txt
##
##
## Description:
## Details of each setting are described with each section that begins with
## a double hashed comment ('##')
## It is up to the user to remove the single hashed comment ('#') from each
## option they want to enable, and to set the specific value of that option.
##
## WARNING: Setting the following combination of parameters will set a
## permanent bit within the SOC and your warranty is void.
## over_voltage>0, and at least one of the following:
## force_turbo=1
## current_limit_override=0x5A000020
## temp_limit>85
##
## Overclock settings will be disabled at runtime if the SoC reaches temp_limit

## Overclocking Settings
##
## ARM, SDRAM and GPU each have their own PLLs and can have unrelated
## frequencies.
##
## The GPU core, h264, v3d and isp share a PLL, so need to have related
## frequencies.
## pll_freq = floor(2400 / (2 * core_freq)) * (2 * core_freq)
## gpu_freq = pll_freq / [even number]
##
## The effective gpu_freq is automatically rounded to nearest even integer, so
## asking for core_freq = 500 and gpu_freq = 300 will result in divisor of
## 2000/300 = 6.666 => 6 and so 333.33MHz.

## Details taken from the eLinux wiki
## For up-to-date information please refer to wiki page.

## Description:
## Details of each setting are described with each section that begins with
## a double hashed comment ('##')
## It is up to the user to remove the single hashed comment ('#') from each
## option they want to enable, and to set the specific value of that option.
##
## WARNING: Setting the following combination of parameters will set a
## permanent bit within the SOC and your warranty is void.
## over_voltage>0, and at least one of the following:
## force_turbo=1
## current_limit_override=0x5A000020
## temp_limit>85

##
## ARM, SDRAM and GPU each have their own PLLs and can have unrelated
## frequencies.

## frequencies.
## pll_freq = floor(2400 / (2 * core_freq)) * (2 * core_freq)
## gpu_freq = pll_freq / [even number]
##
## The effective gpu_freq is automatically rounded to nearest even integer, so
## asking for core_freq = 500 and gpu_freq = 300 will result in divisor of
## 2000/300 = 6.666 => 6 and so 333.33MHz.
