Seeing how well the voltage hacks works on your boards I will include them in armbian (even though I still get crashes on my own board with only this 75mV hack, even though way less).
But not upstream (I am close to sending the eMMC fix upstream, I only need to read the backlog there anew to avoid too much back and forth so the patch is up to the standard). at least until I sort out why they work (I was told to try them by a board designer that told me there was a design issue with the voltage regulator which I am not up to sort out. But I checked other rk3399 armbian boards'schematics and as far as I understand they have the same design. So either all of these boards are broken and are somewhat stable for an unknown reason (maybe less stress on the big CPUs) or I misunderstood what was wrong with helios64 hardware. I need to talk to an hardware engineer.
Also I try to sort out a few other issues with other softwares and hardwares. And a few other issues. But I expect to have those in for mid October, maybe earlier.
Depending on your use case try kernel 6.6.8, 6.1.71, and 5.15.93 (download links are provided here).
Armbian built kernels 6.6.x (x>8) are all unstable.
