Just like the others you go to miner configuration with in it advanced settings. Once you go there the freq and voltage can be changed.
Advanced warning overclocking voids warranty.
Problem is I can't find any values to overclock to...
IE what is voltage for 275?
Checked chip spec sheets for values, almost blew up miner.
you want your voltage brought up to 760 or update to the latest FW then play with Freq settings after that update has set yout voltage to 760 before that these machines are very unstable with any over clock
