I have installed the dagfix version and everything worked fine. I have 10 rx 580 8gb Armor OC and 1 rx 580 8gb red devil GS and it takes around 1700W with bios modding and core voltage to 860 (~330 MH/s. Now i have a question if it is possible to adjust the mvddc, because i belive that it is mor undervolting possible by reducing the memory voltage too around 900. So how is this possible with smOS? I have done the setting in the miner config, but it didn't worked. What else can i do?
I didnt bringed memory undervolting feature to not make this more harder than it is now.
Accually memory undervolting can save about 1-2 watts per gpu. So i guess it isnt worth it !
Only thing that came to my mind is to make overvoltimg in memory which COULD make memory work more stable on very high overclocking.
Accually i am thinking about this but i still am gathering some more informations.
If you want to mess with it then you could manually edit one script and add static memory undervolting by editing:
root/utils/oc_dpm2.sh file
change line
/root/utils/wolfamdctrl -i $x --core-state $coreState --mem-state $memoryState --core-clock ${coreArray[$i]} --mem-clock ${memoryArray[$j]} --volt-state $coreState --vddc-table-set ${coreVoltArray[$i]} #--mem-state $memoryState --mvdd 950
to
/root/utils/wolfamdctrl -i $x --core-state $coreState --mem-state $memoryState --core-clock ${coreArray[$i]} --mem-clock ${memoryArray[$j]} --volt-state $coreState --vddc-table-set ${coreVoltArray[$i]} --mem-state $memoryState --mvdd 950
Or 1000 or whatevery you want
If anyone will have results such as "i saved 5 watts with memory undervolting" or "i make it more stable with 100 MHZ more and now gpus is making 0,5MH/s or something - just let me here know and other people.
If this will really make sense then i will implement it. If it will save 1-2 watt then there is no point right ? I am not as much eco friendly - in other case i would not be mining at all

I set the cvddc to 850 and mvddc too 900 in the file you set. Cclock is at 1200 and mclock is at 2150. Everything runs stable and i can say that its much more cooler know. I also recognized that i have 50 Watts less power drain because of the slower rotation of the fans. 50-62℃ at 40-64% rotation. I didn't get anymore MH/s.
I will try to set mvddc to 850 or around this, to get much less watt consumption with the same MH/s.
