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

Also -i show Test Fail any idea how to solve it ?

Start off with white sticker pics from the back of the card or on the side of the heatsink, then remove the heatsink and get a pic of a ram chip

Also -i show Test Fail any idea how to solve it ?

I program bios from Sapphire Rx 6700 10GB id matched and also have Micron memory and now I cannot go back, I have original bios

I changed bios due in 3D Mark this GPU worked fine but in games I only have iGPU option, and I cannot find solutin to force this GPU as primary.

Currently GPU-Z show blank values and 0Mhz and Amd drivers not see GPU

Buy yourself an SPI flasher and use it. Amdvbflash won't let you flash as it can't detect the card properly.

This is what BIOS chip looks like. Keep in mind that it doesn't have to be on the back of the PCB, it can be on the same side GPU and VRAM are as well.

 

[Rabit]

Any chance to force flashing via Amdvbflash or any other software ?

If not I need desolder bios to flash it via SPI Flasher I try once clip but was rubish and I throw it away

 

[tomcug]

I flashed the RX 6650 XT today with the CH341 programmer and a clip, was a smooth process. I doubt you can force Amdvbflash to program your card, I'd just go for the physical flasher. If it doesn't work, then there's something wrong with clip's contact with the BIOS chip. Just keep reapeating until it works, eventually it must.

 

[Rabit]

Ok Flashed after 3 third attempt looks like P25Q80H chips require erase before write otherwise they making errors.

Remove bios form GPU board solder to adapter, plug to SPI programmer, program it test for bios integrity, de-solder from it and solder back to GPU, Working now

But still I not solved my initial issue with GPU only detected in 3Dmark and not in games.

Afaik ver 5.0 supports up to rx 7900

Afaik ver 5.0 supports up to rx 7900

Probably issue with bios chip P25Q80H even with SPI I succeed after third attempt, when I first full erase it.

 

[Rabit]

Any idea how to force to work in games ?
This is mining GPU no display port * GPU chip have laser off sense pin for detection if monitors is plugged on all ports, I know because I put all smd *( even freaking 0201) and display port on board and not worked and only after this I notice I been fooled due all data signal pins are still connected and have correct resistance values :/

Are you talking about an actual cryptocurrency mining model or is this a gaming card with a modified BIOS?

If it's the former, depending on how it presents to the system you may be able to use Windows' graphics settings and assign software to it:

If it's the latter, don't poke around the hardware, just flash the original VBIOS back. Anything else you do may permanently damage the hardware (and it's already beat up by its former miner owner).

 

[Rabit]

This is actual mining card and under windows I not have option to change only see iGPU
Amd drivers see it as RX 6700 but on sticker model is X080
3dMark see it as Rx 6700
in amd drivera even if I chose in game option Rx 6700, it still using iGPU

Is your performance in games poor? Maybe it's just a visual error that it shows your iGPU there. I assumed your display is plugged into the dedicated card, right?

Ok Flashed after 3 third attempt looks like P25Q80H chips require erase before write otherwise they making errors.

I always erase the chip before flashing. Not sure what chips need it, what don't, so it's just safer that way.

 

[Rabit]

This card do not have display outputs :0 This is mining dedicated one X080

Just buy a new GPU that's meant for gaming and be done with it...

Buying New GPU is lazy and wasteful option, all my PC parts excluding SSD and PSU has been purchased as used or not working example bend pins CPU and mainboard missing trace and few SMD take me some time to fix it for me PC hardware is hobby I feel joy when i save PC part from landfill end

Give me time to research

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

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?

I would repurpose this for folding@home. There's plenty of people here that might be willing to trade you something for it.

Well clearly this card wasn't worth it. Use it for compute tasks like BOINC or F@H and get an actual consumer GPU for games.

I do not know even one guy who do folding@home.

Maybe but this still look like driver lock due if working in 3DMark is possible to find work around.

Tons of people on TPU do it. This forum has a huge community for crunching

Hm.... interesting I seen post a guy who used this same GPU in Razer Core X Chroma for Gaming without any issue.

Ok source?

Fyi creating multiple threads relating to the same problem is against forum guidelines

No guarantee you will ever get the mining gpu working for gaming, besides its bricked

Source is Local Online Market OLX similar to gumtree site and seller claim that used it in that way not English site, also this is not this same guy that I get my GPU
