Bor mitt i Stockholm. Ska prova via Linux och den här guiden.
HOW TO FLASH LC REF VBIOS ON XTXH CARD
1. make LINUX USB Liveboot
1.a Download and Install RUFUS (https://rufus.ie/en/)
1.b Download and burn UBUNTU (https://ubuntu.com/download/desktop)
2. Download XTXH LC Ref Bios from TechPowerUp (can be put inside the same Linux boot USB)
3. Download AMDVBFLASH LINUX Version from TechPowerUp (can be put inside the same Linux boot USB)
4. Insert USB with Ubuntu
4.a Boot from USB and inside Ubuntu select the option that says "Try Ubuntu" (https://ubuntucommunity.s3.dualstac...49a92ce6373041a7f8f50ddf6495f8ac539ad275.jpeg)
5. Inside Linux take AMDVBFLASH and the BIOS from the USB and put it somewhere easy to reach.
5.a Put the rom inside AMDVBFLASH folder
6. Inside the AMDVBFLASH folder, right click and click Open Terminal.
7. Inside terminal run $ sudo amdvbflash -i
7.a This should bring all the GPUs you have installed, there's a number behind everyone of them ,if you have only 1, the number will probably read #0
8. Run this command inside terminal: $ sudo amdvbflash -p 0 biosnamehere.rom to flash
Reboot, load up windows and this should work. I would strongly advise only doing this with double bios cards otherwise you might **** this up and get a bricked card and have to use external flasher.
If it doesn't work or you have any doubts, let me know.
