Are you on windows 20h2?

I am having the same error on my RX570 on a new machine. Did you find a resolution to this. My card works after driver install but if I reboot it kills it.

[Plushka]

bought my rx 580 a week before and having the same issue

[benman2785]

mh, reinstall windows please

if error persist - check if your RX 580 is actually a flashed RX 480 - as this would need a patcher to allow your GPU to run...
did you bought your GPU used?

[WhoAreYou]

This didn't happen to me until 20h2. Different bios are out there all over. Sometimes that is the issue.

I reinstalled Windows. Still happens on install. In October I was able to install my monitor driver it gave me more features, its freesync.

Now they won't let me install it. There putting to much security in the system. I don't feel like admin of my own computer anymore.

Hi, I have that problem and I bought it used and recently I found out that my GPU is flashed rx480. You said I will need a patcher and I don't know what that is. So if you could please help me this problem is killing me and I need my pc to normally for work. Thanks!

[benman2785]

read what i posted (the link with the patcher)

it alters the driver to allow bios-flashed GPUs 

[Tmuka]

Hi I tried using Patcher but unfortunately, it didn't work, it might be because I usually try only amd 580 drivers and this is 480 flashed. Should I try downloading 480 drivers? Thanks!

I have same problem on saphire pulse radeon rx5600xt but no blue screen dont know what to do with it.

Mobo aorus b450 elite Ryzen 5 3600.

This is hapening after any driver instal.

@wasago 

oem1.inf = driver OEM profiles fails

1. run DDU in Safe-Mode to clean old driver
2. reboot and install latest driver (from AMD - not OEM)
3. reboot and test again

@the RX480 to RX580 guy - you could also find the correct bios and flash it back to orginal state - then you dont need the patcher

[wasago]

This is after ddu and driver instal from amd site.

This is happening from begining of owning this pc.

Its prebuild one year old.

@wasago 

as i said: something that your OEM (HP/Dell etc) did is causing a problem.

i would recommend you save your data external and reinstall windows.

i cant rule out an hardware defect - but i am more convinced its a software problem.

so as i said - please install a fresh windows

and again: in oem1.inf are OEM profiles of the company that built your pc.
it is not neccessary for your hw-driver

[wasago]

Thx older driver instalation have diferent oem error like oem46.inf and oem9.inf

But card working ok. on some drivers sometimes gets driver time out but only in opengl games.

[benman2785]

use latest working driver

or simply do a win10 re install

also: dont OC your GPU and maybe flash back orginal Bios

[benman2785]

???

1. run Windows in SafeMode
2. install Driver - DONT REBOOT
3. run patcher
4. reboot - it should work

if it didnt work:
1. run DDU in SafeMode
2. clean old drivers
3. reboot into safe-mode
4. install latest AMD driver
5. reboot into safe-mode
6. run patcher
7. reboot into windows and disable Auto-Driver-Install

if your RX480 is flashed to a RX580 you need to run the patcher when the driver is installed - otherwise it cant work
DONT update driver after patcher was run - if you want new drivers: download them, install them in safe-mode and patch in safe-mode

ps: my RX460 2G is patched to a RX460 2G with all shaders (so its a RX560 now) - i need to use the patcher and it works fine!
