Memtest

memtest86 is a testing software for RAM.

Installation⚑

apt-get install memtest86+

After the installation you'll get Memtest entries in grub which you can spawn.

For some unknown reason the memtest of the boot menu didn't work for me. So I downloaded the latest free version of memtest (It's at the bottom of the screen), burnt it in a usb and booted from there.

Usage⚑

It will run by itself. For 64GB of ECC RAM it took aproximately 100 minutes to run all the tests.

Check ECC errors⚑

MemTest86 directly polls ECC errors logged in the chipset/memory controller registers and displays it to the user on-screen. In addition, ECC errors are written to the log and report file.
