Video BIOS for a Radeon RX 570 4GB graphics card; the name gives no brand, board code or memory vendor. Such a VBIOS is reflashed to the card's SPI chip to recover from a corrupted or failed firmware, using a programmer or a flashing tool like amdvbflash. Memory type and timings must suit the installed VRAM, so check the memory chip make on the card and the board code before writing. Always save the existing image first, and confirm the file size fits the chip.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
