User-space memory subsystem tester

Memtester stress-tests the memory subsystem of your operating system and computer. It repeatedly writes different patterns to all memory locations, reads them back again, and verifies whether the result is the same as what was written. This can help debug even intermittent and non-deterministic errors.

Memtester runs entirely in user space. This means that you don't need to reboot to test your memory, but also that it's not possible to test all of the RAM installed in the system.

It can also be told to test memory starting at a particular physical address.


Install the latest version of memtester as follows:

guix install memtester

Or install a particular version:

guix install memtester@4.6.0

You can also install packages in augmented, pure or containerized environments for development or simply to try them out without polluting your user profile. See the guix shell documentation for more information.
