To test that the RAM is working correctly, the memtester package can be installed:
sudo apt update && sudo apt install memtester
Check how much RAM is available with the free command:
free
This produces the following output:
total used free shared buff/cache available Mem: 945292 64212 609464 696 271616 824816 Swap: 102396 0 102396
In the above example, 824MB are available. To test those 824MB two times, run the following command:
sudo memtester 824M 2
- If the command gets killed by the OOM killer, try testing a smaller amount of RAM.
- To test more than 3GB of RAM, a 64 bit version of Raspberry Pi OS must be used.
- To increase the amount of available RAM, close all other programs. You can also boot the Pi in console mode (
sudo raspi-config, choose options1,S5, andB2) to test the maximum amount of RAM possible.
