Hello

I am new here so please bare with me.

I have a SOYO RX 5700 XT with a problem. It doesn’t POST and doesn’t let me use the PC, even if I use the integrated graphics of the CPU. I have to set it to IGD in ‘Initiate Graphics Adapter’ and enable ‘IGD Multi-Monitor’ in the BIOS, then I can enter Windows normally.

After that I launched GPU-Z and got this (picture). I thought it was a driver issue, so I removed the drivers using DDU and installed new ones. During installation, it reaches between 50% and 80%, then the PC freezes and a blue screen appears (picture). After that I had to force shutdown because it was stuck.

When I powered it on again, this time it freezes at the Windows logo, and I have to force shutdown again. This keeps repeating until I go into Safe Mode and remove the drivers using DDU. After that, I can enter Windows normally again.

I repeated this process with different drivers and the same thing happens, except with version 21.10.2 which reaches 89% then crashes.

I thought maybe it’s a BIOS issue, so I flashed it with a PowerColor BIOS (I know I should use a SOYO BIOS but none of them would flash). The result in GPU-Z stayed the same, only the BIOS version changed from
017.001.000.068.00000 to 0.17.001.000.068.015207 to 017.001.000.049.00000.

Windows after it detect the card as a "Microsoft Basic Display Adapter" will attempt a Driver update on it's on and when that happens the pc becomes sluggish and freeze permanently and I also have to force a shutdown and the same thing happens but sometimes the automatic repairs do a fix its on by deleting some of the drivers and windows return back but gpu-z still display the same thing.

As a last attempt to diagnose it I launched the PCIE render test to see what it could give me and the test started but it was so slow like it was running in 4 fps and the gpu was getting hotter it reached to 92 degrees Celsius (Probably because of the bad thermal pate that I used).

Also, the back of the card is not hot, only slightly warm around the GPU core and VRAM. It’s not a power issue because I tested with an HD 7970 and HD 5850 and it works fine. I’m also sure the card is installed correctly.

I put the card to the repair shop and he did a reball to it (the gpu chip the vram all passed the test) and the technician said the card put an image for about 1 second it went back to how it was and he managed to flash the original bios back but its still the same but now whenever I try to install drivers the system just freeze and no BSOD pop up and I should add that for some reason when I open the amdvbflash program the card will display 8192mb memory in gpu-z and when I shut the program it will go back to 0mb.

Any help will be greatly appreciated, I want to know what the problem and if there is a fix I am really heartbroken.

1) Did it stop posting or it was like that from the get go?
2) Did you keep the original vbios?
3) Can you provide a closer picture of the vram?

1) Yes and No it didn't boot when I first got it but after some power on and off cycle it posted and the whole time it didn't crash at all but after shutting the pc down it went back to what it was like but this time it didn't post again
2) Yes I still have it
3)will this suffice?

The re-balling probably cause more harm than good!
He did not diagnosed the card correctly, he did not identified the issue, he just reballed it, and hoped it will work after that, but it did not.
Now you have the original problem, that you still not know anything about, and you have probably further problems caused by the reball.
I think you need a new card.

Gently wash off the old thermal paste with alcohol, apply new (a little) and install the radiator back. You need to try to flash the card.

The subsystem ID for this one doesn't match mine do I proceed?

Yes.
atiflash.exe -i

atiflash.exe -s 0 backup.rom

atiflash.exe -p -f 0 252008.rom

Upd.

amdflash.exe -fv -fp -p 0 252008.rom

The -fv option ignores the fact that the older version is newer, and -fp ignores the fact that the P/N version is different.
 
Yes.
atiflash.exe -i

atiflash.exe -s 0 backup.rom

atiflash.exe -p -f 0 252008.rom
can you please provide the full code in cmd so I don't make any mistake

Moment..

Create a FreeDOS USB stick using Rufus, then boot from the USB stick not in UEFI mode but via CSM / Legacy BIOS mode. Download version for DOS AMDVBFLASH 4.68 . This is guaranteed to work.

amdflash.exe -fv -fp -p 0 252008.rom

Successfully

Flash, restore and do not touch vbios in the future.

Is there any video I can watch so I can't screw up?
 
There is no video. The situation is difficult, but not a stalemate.

Ask what you don't understand?

Put version 2.93 on the flash drive - it will correctly perform forced writing without errors to empty or third-party subsystem identifiers.

Do I just dump the whole folder in or just amdvbflash.exe?
 
Moment..

I will prepare the file now and you will flash it..

Let's change the version, it's for Windows
do I do the same as I did before and dump the amdvbflash 482kb into the freedos usb?
