VBIOS image for a NITRO+ RX580 8 GB card with Samsung memory, read with the BIOS selector switch set to the right. Memory timings in a video BIOS are tied to the VRAM vendor, so a Samsung-memory card needs a Samsung image like this one. Supplied as a 153 KB RAR, it suits repairing a bricked card or undoing a failed mining or overclock mod by reprogramming the SPI chip. Check the markings on the VRAM chips, note the switch position, and keep a copy of the existing firmware.
