Building a few rigs and need advice on all this custom GPU bios stuff

[coinbeast]

I am building 3 rigs soon and it's only a matter of time before I want to tweak them to get the best hash rate that I can. I have never built a GPU rig before and all this custom bios stuff is a bit daunting to me.

What is the purpose of a custom bios? What can you do with a custom bios that you can't do in an overclocking tool?

How will this affect my cards when it comes time to re sell them?

How do I find out which type of memory my cards have?

MSI Radeon Armor RX 470 4GB

and

SAPPHIRE NITRO Radeon RX 480 4GB

I intend to use SimpleMining OS to run all of my rigs


Thanks everyone

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
