Question How to flash an RX480 Into RX580

Hello, I just bought a Sapphire Nitro+ AMD Radeon RX480 8gb. The card came with corrupt Vbios causing error code 43 even though it was supposedly refurbished, so I reflashed a non-corrupt version of the original bios using AMDVbiosflashwin. Now the GPU works great, however more performance for free is always appreciated, so I would like to turn this card into an rx580 8gb. Since this is a good 480 model, It should handle 580 clocks correct?

When I try to flash a 580 Nitro+ 8gb bios to the 480 using AMDvbiosflashwin the program throws a ssid error. I read to use atiwinflash in command prompt to force the 580 bios on the card, however, ATIwinflash says it cannot find any ATI discrete cards in the system. How do I fix this?

I am using atiwinflash -f -p 0 RX580.rom in the command prompt where RX580 is the new bios file and 0 is my primary GPU (rx480). It brings up a flashing message but says it cannot find any ati GPU.

What can I do to fix this?
Here is my card with current bios and driver version shown: View: https://imgur.com/a/EvyZFGX

you shouldnt flash a 580 bios to a 480 you should edit a 480 bios to the same clocks as a 580 and increase voltages slightly
flashing a 580 bios wont enable more shaders and will most likely brick your card, but editing a 480 bios to 580 clock speeds should work.

No, there’s no warranty the RX480 will work at RX580 speed.

Instead of flashing the BIOS, why not simply overclock the card in Wattman? Much safer and easier...
