Where to get the 64 bit Raspberry Pi OS image for Pi 4 / 400

Pi 64bit OS - Forum Post
Pi 64bit OS – Forum Post

Last year a official 64 bit version of Raspberry Pi OS was released. There have been 3 versions of the image released with the latest one just having came out April 9th 2021.

It can be a little tricky to find and I’ve been asked in the comments here before on the site where to find it so I figured it was time to write a quick guide!

Hardware Used

Raspberry Pi 400 Kit
Raspberry Pi 400 Kit

The Raspberry Pi 400 kit includes everything you need for a full Pi 400 desktop build. The Pi 400 is the fastest Raspberry Pi ever released and comes in the form factor of a keyboard!

Raspberry Pi 4

The Raspberry Pi 4 is available in different memory configurations all the way up to 8 GB. It’s about the size of a credit card and uses an extremely low amount of power making it ideal for all sorts of projects and ideas!

Pi OS 64-bit Image Location

All the beta 64 bit Raspbian images released can be seen at this URL:


You’ll see a directory listing like this:

Pi 64bit OS Images - Directory
Pi 64bit OS Images – Directory

Click on the folder for the latest image available (4-9-2021 at time of writing).

Pi OS 64-bit Image File

The contents of the image folder we selected in the previous step will look like this:

Pi 64bit OS Images - Subdirectory
Pi 64bit OS Images – Subdirectory

The only file most of you will be interested in is the zip file. That contains the entire 64 bit image compressed to a size of about 1 gigabyte. Click the zip file to download it!

Once the download has completed extract the zip file which contains a .img file. In Linux we can extract the file sometimes by just right clicking in the GUI or from the command line using the command:

unzip 2021-05-07-raspios-buster-arm64.zip

If it says you don’t have the unzip utility you can install it with sudo apt-get install unzip. Extraction will take a few moments/minutes on the Pi and then you will end up with the raw .img file in the directory you ran the unzip command. This is the file we will write to our storage!

Writing 64-bit Image to Storage

The recommended way to write the 64 bit image to your storage device is using the Raspberry Pi Imager tool. This works with both SD cards and USB attached storage devices like SSDs/HDDs.

Using this tool for the first step (Operating System) we scroll to the very bottom to select “Use custom”:

Raspberry Pi Imager - Step #1
Raspberry Pi Imager – Use Custom

Once you select this option a prompt will open. From here you can select the .img file we extracted earlier and write the image!

Benchmarking / Testing Storage

Once you’ve booted up you can verify your drive’s performance using my storage benchmark with:

sudo curl https://raw.githubusercontent.com/TheRemote/PiBenchmarks/master/Storage.sh | sudo bash

If you search for the model of your drive on pibenchmarks.com you can compare your score with others and make sure the drive is performing correctly!

21 Dec 2021 : There seems to be a problem with the screen drivers for Pi4 with the latest version of bullseye. I downloaded 2021-10-30-raspios-bullseye-arm64.zip and wrote the card – when I booted the pi, it did some stuff (resized and rebooted, showed the rainbow flash) and then booted to a black screen – never to return.
The magic foo is here on reddit.

In the config.txt file, adjust dtoverlay=vc4-kms-v3d to be dtoverlay=vc4-fkms-v3d
The extra ‘f’ gets the device to use the old driver
No doubt that this will get fixed in time, however for now this may well be of some help to someone..

Cant believe I had to search for this info, it’s utterly ridiculous that 64bit is not the default, let alone not even an option in the recommended installation tool!

The info is appreciated, thanks.

very, very useful
it is bizarre there arent proper forums free from the political nutjobs censoring everything covering things like this. It is getting harder and harder to find information and for normal people to communicate.

I might add – the terminal commands to format and write the image would be useful, so that dependence on the RP SD imager and downloading it isn’t required – Then you don’t need to rely on having a working internet connection – which in some situations (physical, corporate, etc) is a real limiting factor.

You can actually just load the .zip file into the imager – no need to unzip it first.
