Overclocking

Raspberry Pi 400

The Pi 400 already runs at a factory 1.8 GHz, which is significantly faster than the 1.5 GHz of the 4B. We can take it a step further, however, and clock speeds of 2 GHz without any throttling. This is primarily thanks to the Pi 400's massive internal heatsink, which works quite well.

Get started by adding one of these to your /boot/config.txt file.

Running Ubuntu on your Pi? Check /system-boot/config.txt instead.

First Timer: 1.9 GHz

arm_freq=1900
over_voltage=4

Recommended: 2.0 GHz

arm_freq=2000
over_voltage=5

Performance: 2.1 GHz

arm_freq=2100
over_voltage=6

Danger Zone: 2.2 GHz

arm_freq=2200
over_voltage=8
force_turbo=1

Warning: the force_turbo bit will void your warranty!

Raspberry Pi 4B

Since the 4B runs at 1.5 GHz, it's wise to start around 1.8 GHz, instead of 2+ GHz right out the door. Active cooling is a mandatory requirement for overclocking the 4B. You will experience throttling almost immediately without adequate cooling.
