Hi, sorry to disturb you again, is necessary to recompile CGMiner to pass voltage controls?
Cheers W_M
from the code it looks like you need to if you look in the dash_init() in driver_btm_DASH.c the voltage with the stock FW is never set.
listed out the changes now for you.

its literally just custom voltage and slowing the fans so far
I have not tried this your FW, could your FW reboot if there is a "xxxx" error on the board? or MH / S (RT) reduced? If so, then too good.
If you develop it well, even if you charge a fee (just get one, I'm willing to support it). Do not like Blissz, charge life d3, I hate it
haven't implemented this yet maybe some time soon
I am moving to San Diego so my development may be limited in the near future
