## 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
