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.

I know that speed range should be 52-57 but I've found that I can go as low as 50 when I have a problematic chip, see this for example
