dont bother with custom bios.

smOS  allows  settings  similar to msi afterburner  that will save you money.
you are new  get used to mining  first.

If you expand try using the same exact card and purchasing a bios from Eliovp
every card needs a different bios.




I don't both with custom bios I use smOS here are my settings for first card.

I save due to the 1    vs 5 or 6 or 7  in the power stage
I set the core at 1100 vs 1242
I left memory stock at 1650
these two cards are ms rx 470  red  led gaming model





all my rigs  various cards  all can do powerstage 1  which saves money
this is all you need to know  for now
