Okay I may grab one or two  of these.  I am interested in under clocked results.  

so is anyone running freq 187.5  with 0.685 volts?       if so what do you  get for hash rate watts/ power numbers and fan speeds?


better yet has anyone done freq 175 with 0.670 volts?  if so what do you get for hashrate watts used and fan speed?

TIA

Ask and yea shall receive (at least sometimes!):  http://puu.sh/d3BqI/ad9aaf7d23.png - 187.5 at 0.685V.

This is my best config, you can leave 2 front Fans. machine temperature not higher 50 celcius. fan speeds around 3000rpm.
you can find my J7 problem with this way.
if your chain 1 (J7connector is chain1) has higher temperature, you must to check voltage and J7 cable. probably chain1 feeding higher voltage, not our setted voltage. This problem is my nightmare. i am working on it.
