Voltage Offset is a special value that mostly needs to be added to custom mods.
Offset is basically value that will be undervolted from default values.
So for example offset -125mv will substract -125mv from all dpm levels in core level.
This is little difficult but i have some guys that are doing this for me.
Pascal is in deed profitable in dual mining.
Last time i checked it took like 10-15% more wattage.
It didnt lowered any eth mining speed.
And by mining pasc profit was like 20% bigger. IS still is.
check this for example by using my command
claymore-eth miner and this command:
-wd 1 -r 1 -epool stratum+tcp://79.98.144.28:8008 -ewal 0xa35b062b4d386e148dba1417e16b82d9ca1d360d -esm 0 -epsw x -allpools 1 -mport -3333 -dpool stratum+tcp://pasc-eu1.nanopool.org:15555 -dwal 86646-64.442a5627fbc295c2.$rigName/

Yep, normally without undervolt offset 6x470 would take like 1000 wats, mine with custom bios mod are taking about 750 watts with ETH only.
But with ETH+PASC its more 10-15% but it is different thing.
Anyway, offset is the thing thatforces card to take less watts under linux.
Normal undervolting (changing values in polarisbios editor) doesnt work under linux. It works only under windows.
