With its quad-core processor, the Raspberry Pi Zero 2 W already brings an enormous efficiency increase over the older, single-core Raspberry Pi Zero and Zero W. However there’s free, further efficiency buried inside your Raspberry Pi Zero 2 W in the event you’re keen to overclock it? Overclocking any mannequin of Raspberry Pi is a straightforward job. All we have to do is edit a config file and you may achieve, in our expertise, as much as 400 extra MHz (maybe extra) over the 1-GHz inventory pace.
We’ve written up to now about the advantages of overclocking a Raspberry Pi 4 particularly, however the strategies under will solely work on the Raspberry Pi Zero 2 W.
Earlier than you start the method of overclocking your Raspberry Pi Zero 2 W, just remember to have satisfactory cooling. At minimal, you must have a warmth sink on the CPU and chipset, however a fan such because the Pimoroni Fan Shim is best. Word, in fact, that whereas unlikely, it’s additionally potential to wreck your Pi in the course of the course of.
The best way to Overclock a Raspberry Pi Zero 2 W
1. Connect a fan or heatsink to the Raspberry Pi earlier than powering on.
2. Replace the accessible repositories after which improve your Raspberry Pi Zero 2 W. This can guarantee we have now the newest software program accessible.
sudo apt replace && sudo apt dist-upgrade
3. Open config.txt for enhancing. It’s discovered within the /boot listing.
sudo nano /boot/config.txt
4. On the backside of the file make a brand new line and add the next to overclock the Raspberry Pi Zero 2 W to 1.4 GHz and set the GPU to 700 MHz.
#Overclock 1400 arm_freq=1400 core_freq=525 over_voltage=6 gpu_freq=700
5. Save the file by urgent CTRL + X, Y then ENTER.
6. Reboot the Raspberry Pi Zero 2 W. If the Raspberry Pi fails in addition, energy off the Raspberry Pi Zero 2 W, take away the micro SD card and insert it into one other laptop. Within the BOOT partition edit config.txt and verify your settings. You could want to scale back the overclock by 100MHz as a way to boot.
7. With the Raspberry Pi Zero 2 W booted to the desktop, open a brand new terminal window. To see the present CPU pace of the Pi up to date each second use this command.
watch -n 1 vcgencmd measure_clock arm
When idle the CPU pace shall be sub 1 GHz. If we had been to open an online browser or one other heavy utility corresponding to Wolfram, then the CPU pace would improve to satisfy the demand. If we want the pace increase to be all the time on we are able to add an additional line to config.txt which forces the CPU to run on the highest pace.
#Overclock 1400 arm_freq=1400 core_freq=525 over_voltage=6 gpu_freq=700 force_turbo=1
Nonetheless, permitting the CPU to lift and decrease its frequency ends in much less warmth and energy use than having it on the most clock operating always.
