Yess the GPU is second hand.
The previous owner claimed that he only game with the card but I think it was used for mining
For it to be defaced like that yes. The chip is definitely a 6600
Anyways grab the latest bios from the link above and follow this guide 100%, do not skip any steps:
Get the latest version of AMDVBFLASH/ATiFlash
https://www.techpowerup.com/download/ati-atiflash/
Then follow this:
For RX 5000-7000 Navi Series and I believe Vega Cards, maybe Fury...
AMDVBFLASH
Versions 3.31-5.0.567
Follow these steps carefully:
1. Open your "C:" drive in Windows, create a new folder, call it atiflash.
2. Extract the contents of amdvbflash_win_5.0.567.zip to the "C:\atiflash" folder (make sure everything is in C:\atiflash and not another folder)
3. Find the bios file you downloaded and rename the bios file to r6600.rom
4. Move your bios r6600.rom to the "C:\atiflash" folder
5.Open the atiflash folder, double click AMDVBFlashDriverInstaller.exe and allow it to install
YOU MUST INSTALL THIS FOR AMDVBFLASH TO WORK, YOU CAN UNINSTALL IT USING THE EXACT SAME .EXE
6. Open the start menu, type cmd, when cmd.exe appears right click it and hit "Run as administrator"
7. At the command prompt type in cd\ and press enter until only C:\> is on the screen.
8. Type in cd/atiflash and press enter, you should see C:\atiflash>
9. At C:\atiflash> type in amdvbflash.exe -i to identify your card with a 0, 1, or 2
10. At the C:\atiflash> prompt type in
amdvbflash.exe -p 0 r6600.rom -fa -fp (or 1, 2)
(there is a space between amdvbflash.exe and -p, a space between -p and 0, a space between 0 and r6600.rom, a space between r6600.rom and -fa, and a space between -fa and -fp)
Press Enter.
Follow directions on screen and if flash is successful exit the command prompt and restart, windows should show up on monitor
