Hey doktor,
I just picked up a VisionTek Reference RX570 4GB and it shows up as "unknown bios" with your tool (yet works fine in others). I'd like to modify the voltages with it (essentially hardcode into the bios a VDDC offset). I've looked all over and nobody seems keen on sharing how to do it (or write a tool for one).
would you be able to help me out? I would be happy to tip.
I've uploaded my BIOS here:
