Bios mod in RX 570 8 GB

[Mesquitask]

Hello guys, forgive my English, I'm from Brazil, I recently got an RX 570 8GB, it worked perfectly but I found it strange in the rotation of the fans and the bios when pulled by PolariosBiosEditor and GPU-Z, they show totally strange information, looking for real bios of similar cards, I found one from the Sapphire RX 570 8 GB BIOS
(Pulse Mini ITX) https://www.techpowerup.com/vgabios/213125/sapphire-rx570-8192-190411 which apparently could be her, as the memory matches. My plate doesn't have any sticker, so I can't identify its brand.

Taking a look, it has the filename of sam8g.bin, searching on Google I found a bios similar to it.

AMD RX 570 8 GB VBIOS

8 GB GDDR5, 1150 MHz GPU, 1950 MHz Memory

Any tips on how to find the correct bios?

Hello.
In order to narrow the search, we need the following pictures :
- GPU-z main screen
- A picture from labels from the card (front and back of pcb)
- A picture from memory chips (close-up picture with good light) - for this you need to open the card

Hi, I'm not at home right now and I can't send a photo of the GPU-Z, here are some photos I took, as soon as I get there I'll send better photos.

The Gpu doesn't have any label that says its manufacturer, there was just a label that I ended up accidentally removing and it said: "RX 570 8Gb 2048SP". I got this GPU as a gift, I contacted the previous owner so he could see where he bought it but the product link no longer exists and Aliexpress only listed it as RX 570 8Gb Black without mentioning the manufacturer, I sent a print of a similar model that I found on the internet.

It really has 8GB of VRAM, I tested it in some games and when it reaches 5GB or more it doesn't show any artifacts or crashes.

OK.
So indeed you have Samsung memory chips. I can confirm now that you have Samsung FB chips and you have 8gb.
OK.
I need now the pictures from GPU-z.

Hello, sorry for being late, here is the photo of GPU-Z

When I click on Lookup, it redirects me to a generic RX 570 bios

Hello.
The only BIOS i got that matches your card details is the next one.
It is also from a Chinese brand and also a rx570 with 8GB with Samsung FB memory chips.

Thank you very much, I will test, is there any possibility that it won't show video even with compatible memories?
It also has 3 display ports, 1 HDMI and DVI-D

I found this bios here, would it work?

Hello.
Before anything else, you MUST save your current BIOS.
Then you can play as long as you like with new BIOS-es.
Cheers

Ok, I'll test the bios you sent, if everything goes well I'll get back here.

I put the bios you recommended, but the AMD software only recognizes the fan at around 80%, I had to use MSI AFTERBUNNER to leave the default low, how can I fix this?

 

[Imperator]

Well, i would suggest to use DDU and clean the old driver from Windows.

Then Download the driver (or use the one you already have downloaded).

Unplug system from network

Reinstall the driver

Replug the network.

Test it again

 

[Mesquitask]

I did that, it didn't work, I tried flashing it in safe mode and reinstalling the driver again, it didn't work, I went back to the old driver and it's like this:

I'll try another bios to see if it works, I found this one.

Good news! The bios that I sent previously worked perfectly, now the clock and fans correspond correctly to the board, removing that Adrenaline bug. Thanks a lot for the help.
