You can use the inline manual to get more details:įor example, free shows the amount of memory in octets by default, but you can switch to megabytes with: In general, the only thing you’ll look at are the “used” and “available” columns.Īlso, note that “free” is the main command, but many options are available. Available: Rough estimate of how much memory you have available for new tasks.The cache is used to keep data frequently used by the system. Buffers/cache: both are used by your system to improve performance.īuffers are temporary memory used while transferring data from one storage to another.Shared: memory size used by several processes simultaneously.Used: how much memory is used (total – free – buffers – cache).Then you have a bunch of columns, that aren’t necessarily easy to understand, so here are some definitions you need to know: There is one line for memory use and another line for swap use. “Free” gives an overview of the memory and swap usage of a Linux system, detailing it in several columns: total, used, free, etc. If you want to get the same information in command lines, the corresponding command is “free”. On Raspberry Pi OS Lite, there is no graphical tool.

You can also choose to show the main command or the full command line with all the options to get a better idea of which application is using most of your RAM. These are disabled by default, but it might be essential to enable them to get a real overview of the RAM usage. You can show or hide the tasks from the root and other users.

Grab your free PDF file with all the commands you need to know on Raspberry Pi!Īnyway, in this tool, a few options are available under the “View” submenu. “RSS” stands for “Resident Set Size”, which is an indication of how much RAM is allocated to that process, so basically how much RAM the process uses. You can sort the tasks list by clicking on a column title. Above that, Linux will start using the swap partition on your disk, which is generally way slower than the RAM ( more details about the swap here). So, around 10% of RAM is being used, and I have plenty of margins.Ĭonsider that any computer will start to slow down when the RAM used is over 80%, so try to keep it below this threshold. A total of 3793 MB is detected as available on the system, and 441 MB is currently used. In this example, I’m using a Raspberry Pi 4 with 4 GB of RAM. The RAM usage is shown on the right, with the currently used amount of memory and how much RAM is available. Once open, you get a direct overview of the CPU and RAM usage on your Raspberry Pi. It’s the easiest way to check the current RAM usage on the Raspberry Pi. On Raspberry Pi OS with Desktop, a task manager is available under Accessories in the main menu. 5 Ways to Check RAM Usage on Raspberry Pi Task manager The first third of the book teaches you the basics, but the following chapters include projects you can try on your own. It’s a 30-day challenge where you learn one new thing every day until you become a Raspberry Pi expert. If you’re looking to quickly progress on Raspberry Pi, you can check out my e-book here. I will then answer a few common questions about memory usage on Raspberry Pi.

In this article, I will share 5 ways to check the RAM usage on your Raspberry Pi and explain how to analyze the results. In a terminal, the command line “free” can give you an overview of the memory status. With a desktop interface, the easiest way to check the current RAM usage is to use the task manager. That’s why it’s important to keep an eye on your Raspberry Pi’s RAM usage. Recent models have options with up to 8 GB of RAM, but this isn’t the case for all models (most are limited to 1 GB or less). One of the main limitations of Raspberry Pi boards is the amount of memory available.
