Can a buck converter provide variable voltage depending on the clock the miner is set at? Some people said by underclocking it raised their efficiency and that should not happen unless the voltage is variable to an extent or there is more efficiency loss at higher speed.

If it is tied into the main controller then it could be adjusting the voltage, until someone traces the circuit / makes some measurements we will not know.

But agreed as we have all discovered just changing the clock frequency and leaving the voltage the same leaves the efficiency virtually the same. What sort of improvement to efficiency have people seen?

I look forward seeing whether or not the people who said you could underclock to increase efficiency were right. I did not say anything then because i'm not sure its untrue. Maybe they think raising efficiency is just lowering hashrate/clock/consumption.

But we'll see, i think phil or whoever gets a B8 to do test before me will do it, if not i will test it when i receive mine in a week or two(?).
