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.

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

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?

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?

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.

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.

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

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.

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?

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).

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.

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.

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

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

I'd like to know this as well. As far as I can tell, the only thing working is the LED lights, and just barely.

Seems like not a Bricked issue for me but a dead card.

If its not totally detected by your motherboard bios and your OS then its time to RMA it.

This is what I'm thinking as well. I mean the whole card worked fine for a while even after flashing it. It's just when I changed the PSU and added another card (same model) that it died.

I've also gone through the motherboard BIOS on two different computers and haven't been able to see my GPU anywhere.

Did you modded your own bios or downloaded from the internet and flashed to your card ?

I didn't download a bios. I just used the one click timing patch on Polaris and then programmed the modded bios using atiwinflash.

I had a similar experience with my XFX 290 reference series. Hot air gun has brought back my XFX 290 to live. Covering other part using aluminum foil except for a card processor, heat it using Hot Air Gun with a distance between 50cm and temperature 300 degrees (Celcius). My hot air gun has two different temperature (300 and 600). (this is the last thing you can do). If your card still under warranty, just RMA it.

am playing around with this bios card using Hawaii bios editor causing this card dying.  >:(

Did you ever figure out what caused this? Maybe in my case it had something to do with two of the same cards with different bioses being booted?

One thing I actually forgot to mention before was that the riser this card was connected to wasn't working (no lights flashing and the card wasn't detected in windows). Could a faulty riser somehow damage a GPU?

Looks like I'll be RMA'ing this card. First time I've ever had to RMA anything, and it's been quite a headache.

Did you ever figure out what caused this?
In my case, Am just playing around with my R9 bios then am doing something wrong I think.

Maybe in my case it had something to do with two of the same cards with different bioses being booted?
It can be. You do the right way to mod your bios card. But may massive OC causing it or else there something wrong with the electricity, loose socket riser when mounted on PCIe that causes friction, also can break your card.

Looks like I'll be RMA'ing it.
Good choice.

So it looks like the card is powering up now. The LED light is on and the fans are spinning at full speed but the card is still not detected. Given this info, is there anything else I should try before RMA'ing?

I've tried connecting different risers to the card, connecting it directly into the PCI slot, change the PSU leads to the card, flipping the bios switch back and forth, but none of that has worked.

Good progress.


Fans spinning at 100% means the card is not detected and Power On Self Test on your rig didn't finish.
Try this few steps:

Resetting your CMOS
Remove your RAM and Plug it again.
Remove your card then plug it again (better put it directly to PCIe 16X socket)

Then tried to boot again using your card.

If you're certain it's bricked and next step is RMA, then try the paper clip trick. Scary, but worked on mine (flashed the wrong bios)...

Oh yeah, 1+8 method right.  ;)
But may OP card still under warranty, better didn't do physical tweak.

This method used jumper method, connecting a foot IC chip number one and eight. Number one is the one under a small hole in the IC. And number eight is at the opposite end of the number one when we draw a slash of the number one.

one question, Is the jumper should be connected when powering up GPU? I have one dead RX480 reference card and will probably try this out

Would be good if you want to try this method, And please give us an update after.

Yeah. Requires about 6 hands, but you bridge those two poles with a paperclip or similar (I used a stiff wire), then boot. Obviously, you expect an explosion and smoke, but when you get the contact correct it boots up and you can then reflash the correct stock bios. Loads of tutorials online, but it did work for me...

I've tried this but it still isn't working.

My card is still under warranty, so I'd rather not try this.

tried this, totally not worked on my reference card, It seems its really dead, already sent to my supplier for warranties and guess what, they don't ask if its modded or not.. Lol ;D

Good choice.


You are the lucky man.
