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?
There are a plenty of Polaris cards of different producer without any available bios and then the WX-x100 series (amd pro cards) which are not compatible with the timings one click or available on internet. Having a tool like this one available for Polaris cards would be a great advantage, at least for a wx-5100 owner like myself

If this card works under Linux, then the information about the memory and timings may reside in the driver sources. The vbios is also on the card, just a matter of dumping it, as for whether any tool can recognize structures or not, thats a different story.
