In the screenshot I can see that the voltage is set to 1,15V.
I'm using the same HEX miner version (1.0.0.3) and I'm unable to set 1,15V for my HEX16A2 - the maximum I can set is 1,00V.
How can I set the desired voltage?
Ok, I was able to force a setting of more than 1,000V: I opened hexminer.ini and changed "1,000" to e.g. "1,100". This did the trick.
