Ik dacht dat dit juist de cpufreq uitzet?

WARNING: Setting any of the parameters which overvolt your Raspberry Pi can set a permanent bit within the SOC and your warranty is void. Warranty will be voided when you use force_turbo or current_limit_override or temp_limit>85 together with over_voltage>0.[2] So If you care about the warranty, do not adjust voltage.
The latest kernel has a cpufreq kernel driver with the "ondemand" governor enabled by default. It has no effect if you have no overclock settings. But when you do, the arm frequency will vary with processor load. Non default values are only used when needed according to the used governor. You can adjust the minimum values with the *_min config options or disable dynamic clocking with force_turbo=1. [3]
Overclock and overvoltage will be disabled at runtime when the SoC reaches 85°C to cool it down . You should not hit the limit, even with maximum settings at 25°C ambient temperature. [4]
Moet je dan niet handmatig de overvolt instellen?
“None” “700MHz ARM, 250MHz core, 400MHz SDRAM, 0 overvolt”
“Modest” “800MHz ARM, 300MHz core, 400MHz SDRAM, 0 overvolt”
“Medium” “900MHz ARM, 333MHz core, 450MHz SDRAM,
2 overvolt”
“High” “950MHz ARM, 450MHz core, 450MHz SDRAM,
6 overvolt”
“Turbo” “1000MHz ARM, 500MHz core, 500MHz SDRAM,
6 overvolt”
