For rx580 this thing got no use, my opinion. You have allredy stripped firmwares all over the net, why you would use this for 580 This has use for Vega cards because you dont have other option
So that you can experiment with live values instead of BIOS modding every time?
I'm sure those selling the modded bios are annoyed by this, it also keeps warranty's in place.
Not having to mod a bios and worry about warranty etc is a big plus. Now that this is available I have another reason to bite the bullet and try linux.
