Bios seems to be based for a XFX card since the configuration header is XFX_POLARIS20_D00034_XL_GDDR5_8GB\config.h
But boot string is conflicting: D00033 580S A1 GDDR5 256Mx32 8GB 300e/300m

The following bioses have boot string D00034 with Samsung K4G80325FB support
i did a bit of some testing and the first one worked at least for now it has. I haven't seen it crash or do artifacting yet and i only did a stress test for 2 minutes. However drivers work both on sonoma and windows :D. I did try the 2nd and third one you sent and the 2nd one worked but with driver code 43 and the third one didnt even work at all and just didnt give me a display. the fourth one i havent tried since first one seems to be doing its job.
