Topic: Bricked RX 570 - page 2. (Read 502 times)

I wonder how would they find out that the BIOS was modded. 'Cause you know, the GPU is not showing anything .
Maybe someone can explain how the warranty providers find out about the BIOS mod?

I'll try this when I get home. Heading out now for a couple of hours.

1. Unplug the bricked card.
2. Use DDU to delete the amd drivers in safe mode.
3. After a restart windows installs the Microsoft standard drivers.
4. Turn off and plug the bricked card.
5. Now, if you are lucky, you can flash an other BIOS to the card.

It was overclocked to 2250MHz, but it was running fine for a month OC'd, and it was running fine for a week with the modded bios and OC'd. Temperature was also below 60.

Normally if you mod the bios you void the warrenty (I think). However, if the un-modded bios also doesn't work either the card is just bad (or you OC'd it too much).

That is what I did. I've switched back and forth between the modded and unmodded bios both when the PC was on and off, and it's the same result. The fans don't spin and the GPU isn't detected by Windows 10. The only sign of life is the Sapphire logo is flickering weakly.

It's still under warranty, but what's the policy regarding a flashed bios? Would they even be able to tell, given the card can't even power up?

I've personally found that the Nitro+ 570s can be a bit touchy with BIOS modding. I have one that will NOT take a bios mod, no matter what process I use.

Well, if you cannot get it to boot with a flip from BIOS switch I don't believe it's the BIOS that is causing that.

Once again:
1) Turn off your PC
2) Switch to UNMODDED BIOS
3) Boot your rig
        
     Does your GPU show signs of life?


Yes) Congratz!                               No) Possible hardware problem, if under warranty return it

Same issue still even after flipping the bios switch. Fans on the Sapphire RX 570 aren't spinning and it's not being recognized by Windows 10.

Turn the computer off, flip the bios switch to the setting where it will boot.

Turn the computer on.

Once on, flip the switch again. It is ok to flip while it is running.

Flash the bios back to stock and try to mod the bios again.

Sorry, I'm a bit confused. Do you mean flip the bios switch while it's off, then boot into windows on the second bios, flip the switch back to the one that isn't working while its on and flash it back to stock?

And yes, I used Polaris Bios editor and the one click timing. Does that matter?

Disconnect all the cards except for the Sapphire RX 570 Nitro+ 8GB.

Flip the bios switch. Boot into windows. Once booted into windows flip the switch. Flash the bios with the stock bios.

Did you use the Polaris Bios editor (latest version)? If so, did you just click the one click timing button in the bottom right?

Obviously, you want to better performance of mining card, didn't think out of the question, the default is actually very good, so can prolong life, reduce power consumption, I also with before, and then found that time can use came to hang out in fact play with

I flashed my Sapphire RX 570 Nitro+ 8GB about a week ago and it was working fine and was the only card in my franken-rig. Yesterday though, I changed my PSU (from 600W to 650W) and added a second Sapphire RX 570 to my rig, which was running on the stock bios. Upon start up, the fans on both cards were spinning very fast, and eventually the fans and lights on the modded card stopped working and it's not powering up at all now, while the unmodded card is working perfectly fine. I also had the PSU plugged into a watt meter, and it didn't go above 250W, which makes sense since the cards weren't under load.

Some things I've tried to fix this:
1. Testing the PCI slot with another card (which worked), and putting the bricked GPU into another rig (which didn't work)
2. Running ati pixel patcher
3. Running "atiflash -f -p 1 stock.rom" to flash the card back to stock, but I get an error message saying "adapter not found"

I'm now looking into flipping the bios switch, but I'm not sure if there's something else I should try. A lot of people have mentioned flashing/reflashing the card, but I don't know how that would work considering the card won't power up at all, which is why I wasn't surprised I got the "adapter not found" message.

Does anyone have any suggestions before I try to RMA this thing? If I flip the bios switch and it works, is there any way for me to reflash the other bios back to stock? Any help is appreciated.
