An endless loop of make && make clean. The second test is memtester. I ran it for 20 passes for either 1.6GB or 2.6GB. sudo memtester 1600m 20 I have a dedicated microSD card for each test.

Both Manjaro Phosh and Arch Linux ARM come with multiple u-boot bootloaders that let you change the RAM interface speed. I tested at the highest 624MHz and worked down to slower speeds if there were errors. The results: 3 of the boards time travel. This seems to be a side ef
