Graphics card firmware for the NITRO+ RX580 with 8 GB of Hynix video memory, dumped with the dual-BIOS switch in the right-hand position. Because the two positions hold different images, flash this one only to the matching switch setting. The archive is a 153 KB RAR intended for recovering a card that shows artifacts, no output or bad behaviour after a failed mod. Use a programmer on the BIOS chip or a flashing tool, check the memory vendor printed on the VRAM chips first, and back up the original image.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
