I guess I'm just very unlucky, ordering 50gh and receiving 45gh..
I changed i to I, d to D, in every possible way, no way to turn on 38 or any later chip..
Thank you guys for your help, I will try to fire up the 2nd masterboard with the faulty hcard and another psu, but my hopes are already crushed.
Right now its hashing with 20gh, what the..
Have you checked for bad soldering on that particular board? Also the underside of the M-card?

EDIT: especially the I/O pins shorting on that chip 38 would match that behaviour (if you can locate it?)
