I dont now if anyone noticed the "freezer trick" in this video posted above,
https://youtu.be/F6L9hCQ4OhY ,I had some parts of it tranlated by i russian speking friend, and it turned that some hashboard problems can be detected by freezing the board, and there after run it.
I took the hash board board (0) from the T17, that droped off or didn't start, that on irregular bases, (in awesom showing ...4 of 30 asic...) and put it in the freezer for a couple of hours, and it felt stable there after, now on day 2, been minning normal and also starts normal on multible power cycles.
So how is the frozen hashboard doing now? I know the freezing trick works on weakening the adhesive and make the heatsink easier to remove, not exactly sure how it would help to make it stick harder!! I would love to hear more from other members, NFW and wndsnb can perhaps shed some light on the subject.
