Use a custom firmware for S9s, do not meddle with things you do not understand (that tends to end badly for people).

Hello dear fellow Miners,

I am trying to understand how I can change global voltage and frequency on my Antminer S9s using the cgminer API. I have been able to monitor all kinds of things, change pools etc. but I don't quite understand the documentation clearly.

Could somebody provide me an example?

I believe the command below (from the documentation at: https://github.com/ckolivas/cgminer/blob/master/API-README) might be what I need?

Code:
ascset|N,opt[,val] (*)
               none           There is no reply section just the STATUS section
                              stating the results of setting ASC N with
                              opt[,val]
                              This is only available if ASC mining is enabled

                              If the ASC does not support any set options, it
                              will always return a WARN stating ascset isn't
                              supported

                              If opt=help it will return an INFO status with a
                              help message about the options available

                              The current options are:
                               AVA+BTB opt=freq val=256 to 1024 - chip frequency
                               BTB opt=millivolts val=1000 to 1400 - corevoltage
                               MBA opt=reset val=0 to chipcount - reset a chip
                               BMA opt=volt val=0-9 opt=clock val=0-15
                               MBA opt=freq val=0-chip:100-1400 - set chip freq
                               MBA opt=ledcount val=0-100 - chip count for led
                               MBA opt=ledlimit val=0-200 - led off below GHs
                               MBA opt=spidelay val=0-9999 - SPI per I/O delay
                               MBA opt=spireset i|s0-9999 - SPI regular reset
                               MBA opt=spisleep val=0-9999 - SPI reset sleep ms
