i penciled the resistor to about 1230ohms.
Should I have done that or go lower?
I was able to do 1.18k Ohm... I've been steady at around 33Gh/s.
I tuned down to 1.165k, getting around 35Ghash, and 33Ghash/noncerate at the pool. Amazingly, chip #13 which was running at ~300mhash with tons of errors now works just fine.
