After bios flash I bricked GPU and cannot flash back due in AMDVBFLASH I getting Invalid GPU Index

Youre going to trust that as a source? Lmao, fyi you have all the data needed to put a bios on your card

I have zero experience with GPU switching on desktop, no idea if this can work. Out of curiosity, does the RX 6700 really work in 3DMark? What's the score of let's say Time Spy?

It works just fine.

Dude, he already reflashed his card.

Stock settings Max GPU power Draw in GPU-z 138W, GPU max temp 55C hotspot 69C also fan curve annoying idle 1400 rpm Load 2150 RPM , also my test rig is suboptimal like single single Chanel 2400Mhz ;)

GPU score is fine I guess, I have 11400 with a "normal" RX 6700 and Core i9-10900K + fast memory so you're only 10% behind. However, how to make it work in games? No idea from me, maybe someone else has something to say.
 
Thanks for help guys, I mange find solution


This register tweak add switchable GPU option that is present in laptops to desktop now my mining GPU work in all games.
 
Congratulations that you found a solution.
 
Now I sell 5600x and Rx 5700 from my main rig and replace it for 5600G and X080*( Rx 6700) or try add second gpu to be display output.

Give me time to research

1002 **** **** E445 is part of the bios number you need

Your card


2132 Boost core 2000 ram

1002 73DF 1DA2 E445

Sapphire Pulse 6700 10GB bios



This is all we have here.

You may need to contact Sapphire tech support for a correct bios. Let this be a lesson in not buying mining cards and expecting to game on them, they don't have the necessary provisions on the pcb for displays and are cost prohibitive from adding those components.

You need to follow this procedure precisely

Go here and get the latest amdvbflash which is version 5.0.567

https://www.techpowerup.com/download/ati-atiflash/

Then

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 r6700.rom

4. Move r6700.rom to the "C:\atiflash" folder

5.Open the directory/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 -unlockrom 0 (or 1, 2)
(there is a space between the e and -unlockrom and 0)(0 is the number zero)
press enter and you will be prompted that the "ROM Unlocked"

11. At the C:\atiflash> prompt type in
amdvbflash.exe -p 0 r6700.rom -fa -fp

(there is a space between amdvbflash.exe and -p, a space between -p and 0, a space between 0 and r6700.rom, a space between r6700.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
About it I get Unknown Option: unrecognised option '-unlockrom', even after I restored bios looks like amdflash not support mining GPU correctly and initial flash work by accident and corrupted bios

I change bios to original Rx 6700 and UV 1.03V OC +15%TDP

Disregard unknown option message there is a driver in 3.31-5.0.567 that must be installed to unlock the gpus do it can be flashed
 
I get myself entire box of this GPUs now * Price was soo good that I cannot resist I bought them ALL from miner ;)
Now try AMDVBFLASH on new batch and I still getting Invalid GPU Index any solution to flash them via software or I need use my soldering iron and flash them via CH341 ?
