Segfault with GCC in Armbian [Solved].
To continue this story of over and under clocking memory for stability. Here is a graph showing the relative memory bandwidth of the Rock64 with different memory clock speeds.

Again both of the Rock64 single-board computers I have seem stable with the memory clock set to 400 MHz. Since the errors at 786 MHz are intermittent, my guess is the memory could still go a little faster, perhaps 600 MHz or even 666 MHz.
Does anyone know how to make uboot files which initialize the memory at 600 or 666 MHz?
