at lower voltage it will draw more amps for same performance

I think you are wrong. There is no DC/DC converter "inside" the chips Grin

Yeah, i was trying to say something else here Roll Eyes

and too bad avalon did not include some dc/dc reg inside the chips , i spend fortune just for dc/dc controllers Grin

Any way IMHO chips are really power hungry, interested to see that they can "eat" 4+ amps with ease ( @~1.5 - 1.7gh/s ) Cheesy

About i2c i am newbie in that field, i start with mcu's codes and so on ... when i start to work on first miner with bitfury chips, But i think that the i2c lines need to be in pull up, and as much as i know that worked with k16 klondike boards and not changed here at all.

how do you connect boards on raspberry ? hubs ?

@BigJRepairs why do you think you need pull down resistor on SCL/SDA lines ?

@Ostenbacken your code works ok with my boards, but i have 4 chips only at the moment on boards, there is very low error rate, about 1% - running for 8 hours approx @ 1V 1400mhz but i have some wierd situation when i build code and program chip with that .hex, i have higher error rates and simply it just not working like your compiled hex. need to see what is wrong there, i have installed mplabx 2.00 and xc8 1.30, but on 1.85 and xc8 1.20 everything was the same ... so its working but not good. Huh

I hope i will get boards at monday so i will try everything i can before assembling boards. Will post results here ...

Cheers,
