PC falls into bootloop despite being plugged into integrated graphics, after flashing ex-mining RX580 BIOS

[khorrect]

Hey all,

So for the whole day, I've been having problems with my ex-mining RX580, where I hard crash at random times into different colours depending on the page I crash on. I've tried multiple solutions like using just the driver from Windows Update, using an older version of Adrenalin, using the LATEST version of Adrenalin, using AMD Catalyst (note: I also uninstall each driver using DDU before installing the next one). But none of the methods worked...

I came across a video where this guy used ATIFlash/AMDVBFlash to flash his BIOS. Initially, I tried the CMD method but was too dumb to figure it out, so I managed to get my hands on the .exe version and flashed the BIOS.

The .exe was from here:
Post in thread 'Trying to force flash bios using CMD on sapphire rx470' https://www.techpowerup.com/forums/...ing-cmd-on-sapphire-rx470.284015/post-4553409

Unfortunately, after restarting, my PC wouldn't post. So I plugged my monitor into my integrated graphics (with the GPU still plugged in), but it still wouldn't post. I then removed my GPU, and it posted! So I tried the same method again, but with another monitor plugged into my GPU instead (there was another video of a guy posting into BIOS and changing a setting to use integrated graphics instead). But to no avail, it didn't work, and fell into a bootloop instead.

I'm looking to sell this PC soon, so I'm trying everything to fix this GPU before I purchase another second-hand one to replace it. Here's my GPU-Z screenshot:

The BIOS I tried to flash:

Sapphire RX 580 VBIOS

4 GB GDDR5, 1366 MHz GPU, 1750 MHz Memory

My PC specs:
CPU: i5-3470
MOBO: MSI B75MA-P45

The bios I got from VGABIOS matched the GPU clock and Device ID too. Do let me know how to fix this!

EDIT: I realised now that I probably flashed the wrong BIOS, because the memory I have on the GPU is Samsung, but the BIOS is Elpida. My memory clock is also 2000, but the BIOS is 1750.... T_T I think I just need help with identifying the correct BIOS to flash, and also help with booting through integrated graphics with the GPU plugged in, then all should be well, right?

Hello.
In order to narrow the search for the right BIOS for your card, we will need more pictures:
- Labels from your card
- GPU-z > advanced tab and from drop down menu you will choose memory timings

Hi! I bought the card without the backplate on it. My latest development is me flashing this BIOS instead (after managing to change a setting in the BIOS and somehow exiting the bootloop):

Sapphire RX 580 VBIOS

4 GB GDDR5, 1366 MHz GPU, 2000 MHz Memory

But just in case I flashed the wrong one again, here's a screenshot of my memory timings:

Pictures of the part number and sku stickers on the side of the gpu heatsink by the pcie blade are needed, also a picture of a ram chips white alphanumeric characters is needed to make 100% sute of what we are dealing with...

Alright guys update:
I tried installing the latest Adrenalin but it still crashes into random colours and flickering.

I also managed to find some stickers on the GPU! But where do I find the RAM chip though?
