any A4 specific settings yet fellas?
for the moment i use Voltage(mV)(500-850): 826, Ore 1 Speed 1200mhz, difficulty 8192
hashspeed on A4 : 258/260mh/s
hashspeed on website: 220 mh/s
MAXIMUM ! 
Yup I can't seem to push about 2000 mh/s when each one can produce 275 (10 units), should be around 2700 total... similar sort of % missing - is that
