Question Flash BIOS on this GPU ?

[Adry1989]

I have a little problem.
I bought a used MSI 6800 XT Red Devil GPU.
The first owner has messed with it's BIOS and now when I load Windows I lose the DVI signal.
So I would like to re- flash the correct firmware.

The first question:
The GPU has a switch for oc mode and silent mode ... do I need 2 BIOS?

The second question:
How to find the right firmware when there are many firmwares for the same GPU model?
If there is a wrong firmware on the GPU, how to find the right one?

Look at VRAM, it could change within same model GPU.

Hi thanks for the answer.
On the GPU i have oc and silent mode with a switch.
So do I need only one firmware, or this GPU needs two firmwares?

Hello.
Most important AMD partners (Sapphire, XFX, ASUS, MSI and ASrock) make some models with switch.
That is a hardware switch that allows the user to choose what version of the BIOS they will use during boot .
That means BEFORE starting the computer you will move the switch to the desired position and only after that you start your computer.
Depending on what position you chose, it can be "silent" or "performance"
Both BIOS-es are original, they are made by the producer and they are "tuned" by them accordingly.
Well. in real life many cards were used for mining and BIOS-es were modded by people.
In case one of them was "modded" or in some cases both are, you must reflash that BIOS with the original one.
Well, the procedure is not that hard but the user must pay attention to the steps in order to succeed.

Thanks friend. From the GPU packaging box can I find the specification and the correct firmware information?

 

[Imperat0r]

Usually yes, but in some cases is not enough.
To be sure you will need the following pictures.
Load them here using imgur service:
https://imgur.com/?third_party=1

1 - a picture from labels from the card (plus in case you still have it the labesl from the box)
2 - a picture from GPU-z main screen
3 - a picture from GPU-z > advanced tab and from drop down menu you choose memory

That will help us to search for the exact producer, model, ID and memory code.

HI, GPUZ show probably the vga with wrong fw of old proprietary, then it is much difficult to boot the pc and go to windows, freeze or no dvi signal
I attached the photos of box and vga

Hello.
Based on the picture you provided, we have a problem:
Your card for sure it was not made by MSI.
Actually you own a PowerColor RedDevil RX6800 XT
Please check the following link and description and confirm me if your card is this :
https://www.techpowerup.com/gpu-specs/powercolor-red-devil-rx-6800-xt.b8379

And here you have the producer web page:

https://www.powercolor.com/product?id=1606210302

If indeed you have this card, please ask them on support page to provide you the exact BIOS-es for your card and i will help you to flash them.

Hi, i have asked to Power colore for the BIOS but they answer It Is not good. If you have a problem you must contact the seller for Rma they do not send the BIOS of VGA.

 

[Imperat0r]

Pffff.
Ok in this case i will put here a link to another user that we helped.
He had the same card as you and in the link you will find both bios-es: silent and performance

Very unfriendly answer you got from them
I can't believe they did it this way.
And i presume you do not have warranty left at your card in order to initiate RMA procedure?

 

[Adry1989]

I have asked to Power color.
Yes now i have not warranty.
Now i have send email to asrock and amd, I waiting for the answer.
ps the files in post, later a search
are

https://www.techpowerup.com/vgabios/232342/232342

https://www.techpowerup.com/vgabios/234240/234240

they are for a amd rx 6800 xt

 

[Imperat0r]

They are for 6800XT yes.
But they are for your exact model : Power Color Red Devil 6800 XT
So basically if you don't receive from Power Color your BIOS, then you have them here in link above

 

[Adry1989]

You are very kind. One question in gpuz the screen of VGA give memory micron but the rom It Is Samsung memory... Now i do not now if there is a wrong Fw ok on It.

 

[Imperat0r]

then i should search for micron. I will post them here.
I don't have that gpu-z picture.
Would be nice if you can post it here.

Here you have the bios:

Hi, I have taken the 2 rom …

Now the problem

I would to use

amdvbflash_win_3.31

But

If I start the pc

With dvi plug in 6800 start and when load w11… it gives me black screen

If I plug the dvi in integrated vga of mb… I have black screen only from to start

I believe that the pc starts but or I lost the signal video or the signal do not start from mb but start from vga

hello.
start the computer with the video card 6800.
enter in the BIOS during boot.
There you will choose what video card will be used (onboard or 6800).
Only after that you will restart computer and this time you will use as the main video card the onboard one.
