Am I the only one who's noticed the new PDF on Bitmaintech's website with step-by-step instructions on how to solder capacitors directly to each hashing board....
"Guideline for soldering Capacitors to S2 hash board to fix chip disabling issue"
eek.... happy long weekend to me...
That sucks

.
Factory defect on this batch or engineering oversight? How many blades are in an S2? 4 caps per blade need to be added if I understand correct?
Maybe half the chips are disabled, and this + a 2nd PSU is part of bitmains post about being able to OC each S2 to 1.8-2Thash cheaply?
