This has to do with the software compatibility which is by far the biggest reason to upgrade to 64 Bit OS.Įxcept in RPI boards and embedded computer systems, the 32-bit OS version is used nowhere. So now the 64 bit OS gives you the ability to use full onboard RAM for a single process. But in some cases like data processing, where one process could use more than 3 GB, you definitely need 64 bit OS. So for most applications that you run on Pi boards, RAM is not an issue. So things are good as long as you are not planning to do heavy work on the system. But most of the processes do not require more than 3GB of RAM like using Chromium browser. Note: The limitation of this “ Large physical address extension” method is that any single process cannot use more than 3 GB of RAM. That’s why by upgrading to 64 Bit OS you can save the hassle of implementing these weird hacks. Only by using the “ Large physical address extension” method, you can do so. Then memory is not an issue as 32 bit OS can address 4GB of memory easily.īut if your board has more than 4GB of RAM, then 32-bit OS would not be able to address more than 4GB of space. If you have 32 bit OS installed on the board that has less than 4 GB of RAM. Should I upgrade to Pi 64-bit OS? IF your board has more than 4GB of RAM However for the majority of day-to-day applications like web browsing, booting and documentation there’s not much difference in speed. For example: running 4K videos on 64 Bit is much more stable and smooth. Yes, the 64-bit OS is indeed faster, performs better, and consumes less power than 32-bit OS. So addressing 8 GB of RAM is a piece of cake using this method. Using a Pi OS method called “Large physical address extension” which allows a process on ARM 32 bit to access up to 1TB of RAM. Technically it’s not possible but here’s how to do it: ![]() How to address more than 4GB of RAM using a 32-bit Pi OS? Hence a 32 Bit OS is limited to 4GB of Ram irrespective of the 64 Bit architecture of the new RPI boards. This is calculated by this formula: 2^32 = 4GB. How much memory can 32-bit OS address?Ī 32 Bit OS or architecture cannot address more than 4GB of RAM. The 32 bit OS is still compatible with every single RPI board ever made and will continue to do so for the upcoming years. Whereas older boards like Pi Zero, Zero W, RPi 1, and RPi 2 do not support 64-bit OS as they have a 32-bit architecture. This 64 bit OS is compatible with only the newer generation RPi boards that have 64-bit architecture: RPI 3, PI 4, Zero 2W, and RPI 400. Which Pi boards are compatible with RPI 64-bit OS? It runs on those Rpi boards that have Rpi’s 64-bit architecture. Raspberry pi 64 bit OS is the updated and enhanced version of the 32 bit OS. That's why this version of the OS is called Raspberry Pi OS and not Raspbian.( learn more) What is RPI 64-bit OS? Note: The RPI 64-bit OS is not based on Raspbian. Manually install the 32 bit version of Chrome on 64 bit Pi OS.Are there any issues with RPI 64-bit OS?.How to address more than 4GB of RAM using a 32-bit Pi OS?.Which Pi boards are compatible with RPI 64-bit OS?. ![]()
