Im not entirely sure, but I'd say that chip 38 is dead and since they are chained any chips beyond it will not function.
I have a h-card with chips 7-16 inclusive which are dead, chip 16 barely hashes setting its speed at 50, but throws a ton of miso-errors.

During the night, the half-dead card got worse, now it is at 5 GH/s with a little more than 1/4 of the chips still mining.
I've already removed auto-tuning, but it had no effect, even chips that yesterday night were mining now show 0.
This afternoon I'll start visually inspecting all the cards to see if I have soldering defects.
